Cosmos Double Click Rose Bon Bon

Pink cosmos bipinnatus ‘double click rose bon bon’ closeup | i fleur

Cosmos ‘Double Click Rose Bon Bon’ is a tall, romantic garden cosmos prized for its fluffy rose-pink flowers. Unlike the simple daisy-like blooms most people associate with cosmos, this cultivar produces a mixture of fully double and semi-double flowers, creating a ruffled appearance that can resemble small pompons or loose garden roses.

The flowers are especially useful for cutting. They grow on long, slender stems above finely divided, feathery foliage, making ‘Double Click Rose Bon Bon’ an excellent choice for cottage gardens, cutting gardens, mixed borders, and informal summer plantings.

It is also surprisingly easy to grow.

Like other Cosmos bipinnatus cultivars, ‘Rose Bon Bon’ thrives in sunshine and well-drained soil without demanding rich fertility or constant attention. In fact, overly fertile soil can produce enormous leafy plants with fewer flowers.

For gardeners who love pink flowers but want something more unusual than a standard single cosmos, ‘Double Click Rose Bon Bon’ is one of the most attractive choices in the Double Click series.

🌺 What Is Cosmos Double Click Rose Bon Bon?

‘Double Click Rose Bon Bon’ is a cultivated variety of Cosmos bipinnatus, commonly called garden cosmos or Mexican aster.

The species is known for tall, branching plants with exceptionally fine, thread-like foliage and large daisy-shaped flowers.

The Double Click series takes the familiar cosmos flower in a different direction.

Instead of producing only one ring of broad ray florets around an exposed yellow center, Double Click plants produce additional layers of florets.

Individual flowers can therefore range from:

Semi-double
Loosely ruffled
Anemone-like
Fully double
Pompom-like

That variation is part of the cultivar’s charm.

Do not expect every flower on every plant to look completely identical. Some blooms may have dense centers, while others retain a more open cosmos appearance.

🌹 What Color Is Double Click Rose Bon Bon?

The flowers are best described as rose pink.

Depending on flower age, sunlight, growing conditions, and individual variation, blooms may appear:

Medium pink
Rose pink
Blush rose
Deeper rosy pink toward the center
Slightly softer as the flower ages

The color is strong enough to show clearly in a border without becoming as intense as magenta or cranberry cosmos.

It combines especially well with white, lavender, blue, burgundy, and softer pink flowers.

🌸 What Do the Flowers Look Like?

The main attraction is the unusual double flower form.

‘Rose Bon Bon’ produces blooms approximately 2 to 3 inches across with multiple layers of ruffled rose-colored florets.

Some are extremely full.

Others are semi-double with a visible central disk.

This means a single plant may produce flowers that look slightly different from one another.

Against the plant’s delicate fern-like foliage, these densely textured blooms appear even fuller.

That contrast—fluffy flowers above airy foliage—is one of the features that makes Double Click cosmos so useful in cottage-style planting.

🌿 Double Click Rose Bon Bon vs. Regular Cosmos

Traditional Cosmos bipinnatus flowers are usually simple and daisy-like.

A typical flower consists of broad outer ray florets surrounding a yellow central disk.

‘Double Click Rose Bon Bon’ has been selected for a much fuller form.

Feature	Regular Cosmos	Double Click Rose Bon Bon
Flower form	Usually single	Semi-double to fully double
Color	Depends on cultivar	Rose pink
Texture	Simple, daisy-like	Fluffy and ruffled
Height	Varies widely	Roughly 3–4 ft.
Cut flower use	Excellent	Excellent
Garden style	Meadow, cottage, informal	Cottage, cutting, romantic borders

Both are easy annuals, but ‘Rose Bon Bon’ offers considerably more flower texture.

📏 How Tall Does Double Click Rose Bon Bon Grow?

Expect mature plants to reach approximately 3 to 4 feet tall.

Johnny’s Selected Seeds lists plants around 42 to 46 inches tall, while the Royal Horticultural Society describes ‘Double Click Rose Bonbon’ at about 90 centimeters, or roughly 3 feet.

Differences like these are normal.

Final height is influenced by:

Soil fertility
Water
Spacing
Light
Climate
Growing-season length
Whether plants are pinched
Wind exposure

Rich soil can produce particularly tall, leafy plants.

For most garden planning, treat ‘Rose Bon Bon’ as a tall annual rather than a compact bedding flower.

📐 How Wide Does It Grow?

Individual plants branch as they mature and can create a substantial airy mass.

Spacing them approximately 9 to 12 inches apart works well for cut-flower production and dense garden displays.

Plants grown farther apart tend to develop thicker stems and more branching room.

Closer planting can help neighboring tall plants support one another, but excessive crowding may reduce airflow.

Give them enough room to branch without isolating each plant so much that wind becomes a greater problem.

📅 When Does Double Click Rose Bon Bon Bloom?

Flowers generally begin appearing in summer and can continue until frost if plants are regularly harvested or deadheaded.

Johnny’s lists approximately 75 to 90 days from seed to maturity.

Actual flowering time varies with:

Sowing date
Soil temperature
Sunlight
Summer temperatures
Transplanting
Plant stress

Plants started indoors may establish earlier than direct-sown plants, although cosmos grow quickly enough that direct sowing remains very practical.

Once flowering begins, regular cutting can keep new buds developing for months.

❄️ Is Double Click Rose Bon Bon an Annual or Perennial?

It is an annual.

The plant germinates, grows, flowers, produces seed, and dies within one growing season.

Frost ends the season in climates with cold winters.

That does not necessarily mean you will never see cosmos in the same location again.

Cosmos bipinnatus can self-sow where conditions are favorable.

However, seedlings arising naturally the following year may not all reproduce the exact same highly double rose-pink appearance, particularly when other cosmos cultivars have been growing nearby.

☀️ How Much Sun Does Rose Bon Bon Cosmos Need?

Plant it in full sun.

At least six hours of direct sunlight per day is a good target, with longer exposure usually producing stronger flowering.

Insufficient sunlight can contribute to:

Taller, weaker stems
Leaning plants
Reduced flowering
Less compact branching

Cosmos are naturally suited to bright open spaces.

A sunny cutting bed, cottage border, vegetable-garden edge, or open flower bed is ideal.

🌱 Best Soil for Double Click Rose Bon Bon

One of the best things about cosmos is that they do not require rich soil.

Average, well-drained garden soil is usually sufficient.

University of Illinois Extension specifically recommends well-drained soil with relatively low fertility for garden cosmos.

This may seem surprising because gardeners often assume flowering plants need large amounts of compost and fertilizer.

Cosmos can react to excessive fertility by producing lots of lush green growth at the expense of flowers.

A moderately lean soil often creates a better balance between stems, foliage, and blooms.

🚫 Don’t Overfertilize Cosmos

More fertilizer does not necessarily mean more flowers.

This is especially important with a tall cultivar such as ‘Rose Bon Bon’.

Too much nitrogen can contribute to:

Excessively tall plants
Floppy stems
Dense foliage
Delayed flowering
Fewer flowers

If your garden soil already grows vegetables or annual flowers successfully, additional fertilizer may not be necessary.

Container-grown plants are different because nutrients gradually wash from the potting mix. Even then, fertilize lightly rather than treating cosmos like heavy feeders.

💧 How Much Water Does Double Click Rose Bon Bon Need?

Keep seedlings reasonably moist while they establish.

Once mature, cosmos tolerate occasional dry conditions better than many thirsty annual flowers.

Water deeply when conditions become genuinely dry rather than constantly keeping the soil saturated.

Overwatering can encourage:

Excessive foliage
Weak growth
Root problems
Fewer flowers

Plants in containers require more frequent watering than those growing in the ground.

During extreme heat, check plants regularly rather than relying on a fixed schedule.

🌱 Growing Double Click Rose Bon Bon From Seed

Cosmos are exceptionally easy to grow from seed.

You have two main options:

Start seeds indoors.
Sow them directly into the garden.

Both methods work.

Starting indoors can provide slightly earlier plants, while direct sowing eliminates transplanting and requires very little equipment.

For a large cutting garden, many growers use both methods to spread out flowering.

🪴 When to Start Rose Bon Bon Cosmos Indoors

Start seeds approximately 5 to 7 weeks before you plan to transplant outdoors.

Use a light seed-starting mix and cover the seeds only lightly.

Provide bright light as soon as seedlings emerge.

Avoid starting too early.

Cosmos grow rapidly, and seedlings held indoors for excessive periods can become large and difficult to manage.

The goal is to produce healthy young transplants—not mature flowering plants inside the house.

🌡️ Cosmos Seed Germination Temperature

Johnny’s recommends germination conditions around 68–72°F.

Under appropriate conditions, seeds often germinate within approximately 7 to 10 days.

Maintain moderate moisture during germination.

Do not saturate the seed-starting mix.

Once seedlings emerge, strong light becomes essential.

Warm temperatures combined with insufficient light can quickly produce thin, stretched plants.

🌱 Direct Sowing Double Click Rose Bon Bon

Direct sowing is one of the easiest ways to grow this cultivar.

Wait until the danger of frost has passed and soil has warmed.

Johnny’s recommends direct sowing once soil temperature is above approximately 60°F.

Other extension recommendations for garden cosmos commonly suggest waiting until soil is around 65°F.

Sow seeds shallowly and cover them lightly.

Keep the upper soil consistently moist until germination occurs.

Once seedlings become established, they need considerably less attention.

📏 How Deep Should Cosmos Seeds Be Planted?

Cosmos seeds should be planted shallowly.

Approximately ¼ inch deep is sufficient.

Deep planting can delay or reduce germination.

You can make a shallow furrow, distribute seeds, and lightly cover them with loose soil.

For indoor seed starting, press seeds into moist seed-starting mix and add only a thin covering.

🌱 How Far Apart Should Rose Bon Bon Cosmos Be Planted?

Aim for approximately 9 to 12 inches between plants.

This is particularly useful when growing them for cutting.

Wider spacing can encourage thicker stems and broader individual plants.

For a decorative cottage garden, spacing does not need to look rigid.

You can arrange plants in loose groups while maintaining enough room for airflow.

Remember that a tiny seedling can eventually become a plant roughly 3 to 4 feet tall.

✂️ Should You Pinch Double Click Rose Bon Bon?

Yes, pinching is useful.

Removing the central growing tip while plants are young encourages them to branch.

More branches can mean:

More flowering stems
Bushier plants
A better cutting habit
Less dependence on one main stem

Allow seedlings to establish first.

Once plants are several inches tall and growing actively, remove the upper growing tip just above a set of leaves.

Side shoots will begin developing below the cut.

Pinching is not absolutely necessary, but it is particularly useful when growing cosmos for bouquets.

🌿 Does Double Click Rose Bon Bon Need Support?

It can.

The cultivar can grow more than 3 feet tall on relatively slender stems.

Plants may lean or topple after:

Heavy rain
Strong winds
Thunderstorms
Excessive fertilizer
Growing in partial shade

Johnny’s specifically notes that tall cosmos may benefit from horizontal support netting.

Penn State Extension also recommends grid-style support for cosmos.

In a home garden, simpler methods work too.

You can use:

Stakes and garden twine
Peony rings
Horizontal flower netting
Neighboring plants for support

Installing support while plants are still small is much easier than trying to rescue flattened mature plants.

🌬️ Where Should You Plant Tall Cosmos?

Choose an open sunny location but consider wind exposure.

A site that receives strong afternoon thunderstorms or constant wind may benefit from nearby structural support.

Good locations include:

Against a loose fence
In the middle or back of a cottage border
In a dedicated cut-flower row
Among other tall annuals
In a sheltered sunny courtyard

Do not hide the plants completely at the back of a bed.

The double flowers deserve to be visible.

🌸 How to Get More Double Click Cosmos Flowers

The most important technique is simple:

Keep cutting the flowers.

Cosmos are classic cut-and-come-again annuals.

Removing flowers prevents the plant from putting all of its energy into mature seed production.

That encourages additional buds and branches.

For maximum flowering:

Give plants full sun.
Avoid heavy fertilizer.
Pinch young plants.
Harvest flowers frequently.
Deadhead flowers you do not cut.
Water during significant drought.

A neglected cosmos plant can still flower, but a regularly harvested one generally remains productive much longer.

✂️ Deadheading Double Click Rose Bon Bon

Deadheading is strongly recommended.

Johnny’s specifically notes that deadheading is necessary for continued summer flowering.

Once a flower declines, cut the stem back rather than merely pulling off the faded petals.

Follow the stem down to a healthy branching point or developing bud.

This produces a cleaner plant and encourages useful new stems.

If you want to save seed, allow selected flowers to mature late in the season while continuing to deadhead the rest.

💐 Is Double Click Rose Bon Bon a Good Cut Flower?

Yes—this is one of its strongest uses.

The cultivar was selected in part for cut-flower production.

It provides:

Long stems
Romantic rose coloring
Unusual double flowers
Airy foliage
Good bouquet texture
Repeated harvests

The blooms can look almost like miniature peonies when fully double.

They combine especially well with simple flowers because their ruffled texture provides contrast.

✂️ When to Cut Double Click Cosmos

For fresh flowers, Johnny’s recommends harvesting when the petals are just beginning to open but have not yet flattened completely.

Do not wait until an aging flower has been fully open in the garden for several days.

Cut stems early in the morning or during another cool period when plants are well hydrated.

Use clean snips or pruners.

Cut deeply enough to obtain a useful stem for arranging.

Deep harvesting also encourages the plant to produce longer replacement stems from lower nodes.

💐 Flowers to Pair With Rose Bon Bon Cosmos

Rose-pink double cosmos are remarkably easy to use in bouquets.

Good companions include:

Zinnias
Snapdragons
Dahlias
Celosia
Ammi
Bachelor’s buttons
Gomphrena
Basil flowers
Sunflowers
Ornamental grasses

White flowers soften the rose coloring.

Burgundy and cranberry flowers create a richer late-summer palette.

Blue and lavender flowers provide cool contrast.

For a romantic arrangement, combine Rose Bon Bon with white and blush flowers plus delicate foliage.

🌸 Double Click Rose Bon Bon in Cottage Gardens

This cultivar looks particularly natural in a cottage garden.

Its tall stems and feathery foliage create movement rather than a stiff block of color.

Plant it among:

Zinnias
Coneflowers
Salvias
Snapdragons
Nicotiana
Dahlias
Black-eyed Susans
Verbena

Allow plants to weave slightly through neighboring flowers.

The formal-looking double flowers contrast beautifully with an informal planting style.

🎨 Double Click Rose Bon Bon Color Combinations

Rose pink is remarkably versatile.

Rose Pink and White

Soft and romantic.

Try white cosmos, white zinnias, or pale snapdragons.

Rose Pink and Burgundy

Rich and sophisticated.

Double Click Cranberries makes an obvious companion.

Rose Pink and Lavender

Excellent for cottage gardens.

Lavender salvias and verbena can provide vertical contrast.

Rose Pink and Yellow

Bright and cheerful.

Use yellow zinnias, black-eyed Susans, or sunflowers.

Rose Pink and Green

Let foliage become part of the design.

Cosmos’ own fine green leaves already provide an attractive backdrop.

🌺 Rose Bon Bon vs. Double Click Cranberries

These two members of the Double Click series share similar growth habits but offer very different colors.

Rose Bon Bon produces medium rose-pink flowers.

Double Click Cranberries produces much darker cranberry-colored blooms.

Both generally reach approximately 42–46 inches under the growing conditions reported by Johnny’s and produce semi-double to fully double 2- to 3-inch flowers.

Planting them together creates a beautiful tonal combination ranging from pink to dark berry.

🤍 Rose Bon Bon vs. Double Click Snow Puff

Double Click Snow Puff produces white double and semi-double flowers.

Rose Bon Bon provides the pink counterpart.

Together they can create a particularly effective romantic cutting garden.

White flowers also make the rose tones appear stronger when viewed from a distance.

Add Double Click Cranberries and you have a simple three-color planting of white, rose, and deep cranberry.

🌸 Rose Bon Bon vs. Double Click Bicolor Pink

The names can sound confusing.

Rose Bon Bon is primarily a solid rose-pink selection.

Double Click Bicolor Pink produces more obvious variation and bicolored pink effects.

Choose Rose Bon Bon when you want a consistent rosy palette.

Choose Bicolor Pink when you prefer more visible variation among the flowers.

Both can be mixed successfully in an informal cutting garden.

🌿 Does Rose Bon Bon Cosmos Attract Pollinators?

Cosmos bipinnatus is widely recognized as a useful flowering plant for bees, butterflies, and other pollinating insects.

However, there is an important consideration with double flowers.

Extra petals or ray florets can make the flower’s central pollen and nectar resources less accessible than they are in an open single cosmos.

Rose Bon Bon plants may also produce semi-double flowers with more accessible centers, but gardeners whose main goal is pollinator support should consider growing some single-flowered cosmos alongside Double Click varieties.

That approach provides both the ornamental appeal of double flowers and easy-to-access open blooms.

🦋 Using Cosmos in a Pollinator Garden

Instead of planting only one cultivar, combine Rose Bon Bon with single-flowered Cosmos bipinnatus varieties.

This creates:

More flower forms
Greater visual diversity
More accessible flowers
A longer, fuller display

You can also combine cosmos with zinnias, native asters, coneflowers, mountain mint, and other flowers suited to your region.

A diverse planting is generally more useful than depending on a single ornamental cultivar.

🌡️ Does Cosmos Tolerate Heat?

Cosmos are warm-season annuals and generally handle summer conditions well.

However, extreme heat can slow flowering in some climates.

Missouri Botanical Garden notes that Cosmos bipinnatus may slow considerably during very hot and humid late-summer weather.

Plants often improve again when conditions moderate.

Keep them watered during prolonged drought, but avoid responding to hot weather by saturating the soil every day.

💧 Is Rose Bon Bon Drought Tolerant?

Established garden cosmos have useful drought tolerance.

Young seedlings still need reliable moisture.

Recently transplanted plants should not be allowed to dry severely before their roots establish.

Mature plants can handle short dry periods, particularly in the ground.

Flower production may decline during prolonged drought, so water when dry weather becomes significant.

The goal is resilience, not deliberate stress.

🪴 Can Double Click Rose Bon Bon Grow in Containers?

Yes, but this is a tall cosmos, so choose a substantial container.

A tiny patio pot is not ideal for a plant approaching 4 feet tall.

Use:

A large container
Drainage holes
Quality but not excessively rich potting mix
Full sun
Stakes if necessary

Container plants require more frequent watering than garden-grown cosmos.

Avoid extremely high-nitrogen liquid fertilizers, which can produce enormous leafy plants.

If you mainly garden in containers and want a very compact cosmos, a dwarf cultivar may be easier to manage.

🌱 Does Double Click Rose Bon Bon Self-Seed?

It can produce viable seed and is listed as open-pollinated.

However, seed saving comes with an important caveat.

Cosmos can cross-pollinate with other compatible Cosmos bipinnatus plants growing nearby.

If several varieties flower together, seeds collected from Rose Bon Bon may produce offspring with different colors or flower forms.

Even without obvious crossing, double-flowered characteristics can show some variation.

Seed saving is therefore fun if you enjoy surprises.

If you need plants that closely match the named cultivar, purchasing fresh seed from a reliable supplier is more predictable.

🌱 How to Save Rose Bon Bon Cosmos Seeds

Stop deadheading a few healthy flowers near the end of the growing season.

Allow the flower heads to mature and dry on the plant as much as weather allows.

Cosmos seeds become long, narrow, dark structures radiating from the center.

Collect mature dry seed before it falls naturally.

Allow harvested seed to dry thoroughly indoors before storage.

Store it in:

A paper envelope
A labeled seed packet
A cool location
Dry conditions
Darkness

Always label the cultivar and year.

If other cosmos varieties were nearby, add a note that the seedlings may not come true.

🍂 What Happens to Rose Bon Bon After Frost?

Frost usually ends the plant’s life.

Once plants are killed by freezing temperatures, pull them or cut them at ground level.

Healthy plant material can be composted.

If you want volunteers next year, leave a few mature seed heads before cleanup.

If you want greater control over next year’s planting, remove seed heads and start again with purchased or saved seed in spring.

There is no underground crown that needs to be protected through winter because this cultivar is an annual.

🦠 Common Cosmos Problems

‘Double Click Rose Bon Bon’ is generally easy to grow, but potential problems include:

Powdery mildew
Gray mold
Stem canker
Aphids
Leafhoppers
Caterpillars
Wind damage

Good spacing, full sun, and reasonable watering reduce many problems.

Avoid constantly wetting foliage late in the day when disease pressure is high.

The most common “problem” in home gardens may actually be excessive growth caused by rich soil and fertilizer rather than pests or disease.

🌿 Why Is My Rose Bon Bon Cosmos Tall but Not Flowering?

The most likely causes include:

Too Much Fertilizer

Excess nitrogen encourages leaves and stems instead of flowers.

Too Little Sun

Cosmos flower best in full sun.

Starting Too Early

Large plants kept indoors for too long can become stressed.

Very Hot Weather

Extreme summer heat can temporarily slow bloom.

Excessive Water

Constant irrigation can encourage lush vegetative growth.

If the plant looks enormous and perfectly green but produces few buds, resist the temptation to add more fertilizer.

🌬️ Why Is My Cosmos Falling Over?

Tall cosmos can become top-heavy.

Common reasons include:

Strong wind
Heavy rain
Excessively rich soil
Too much water
Insufficient sunlight
Lack of support

Use stakes, twine, or horizontal netting if needed.

Pinching young plants also encourages branching and can create a sturdier structure.

Plants in exposed locations may require support even when grown correctly.

🌸 Why Are My Rose Bon Bon Flowers Not Fully Double?

This cultivar naturally produces a mixture of fully double and semi-double flowers.

A flower that displays part of its center is not necessarily defective or mislabeled.

Variation in doubleness is characteristic of the Double Click series.

Growing conditions and individual plants can also influence flower appearance.

If you require perfectly uniform florist-style flowers, cosmos may provide more variation than highly controlled greenhouse crops.

In a garden, that variation adds character.

🌸 Is Double Click Rose Bon Bon Worth Growing?

Cosmos ‘Double Click Rose Bon Bon’ is an excellent choice for gardeners who want an easy annual with the appearance of a much more elaborate flower.

The plant itself retains everything that makes garden cosmos useful: airy foliage, quick growth, tolerance of relatively lean soil, a long flowering period, and simple seed propagation.

The flowers are where it becomes special.

Instead of ordinary single cosmos blooms, Rose Bon Bon produces layers of rosy florets that can look fluffy, ruffled, and almost peony-like. Some flowers are densely double, others semi-double, and that slight variation gives a planting an informal romantic quality.

It is particularly worthwhile for a cutting garden.

Plant a row in full sun, pinch the young plants, provide support before they become tall, and begin harvesting as soon as flowers start opening. The more consistently you cut and deadhead, the longer the plants can keep producing new stems.

Just avoid pampering them too much.

Cosmos do not need rich soil or heavy fertilizer. Give Rose Bon Bon sunshine, drainage, modest water, room to branch, and regular cutting instead.

By midsummer, those tiny spring seeds can become 3- to 4-foot plants filled with rose-pink double flowers—and they can continue producing bouquets until frost finally brings the season to an end.
