Description

Cosmos 'Double Click Snow Puff' is a spectacular selection featuring fully double, pompom-like blooms on strong stems. The pure white flowers are occasionally suffused with a delicate hint of blushed pink. They appear all season long on tall plants, ideal for cutting! Easy to grow and effortlessly romantic, Cosmos thrive in light soil in a sunny position.

Cosmos bipinnatus is a tender annual plant native to Mexico and the southernmost part of the United States. It belongs to the Asteraceae family alongside Dahlias and daisies, featuring the characteristic inflorescences known as capitulums and very fine, feathery foliage. 'Double Click Snow Puff' quickly forms large clumps, about 90 cm tall and 50 cm wide. Flowering starts in June-July, 60-90 days after sowing, and lasts until October (or the first frosts). The flower heads measure about 7 cm across and are made up of several layers of petals arranged around a golden central disc. The fully double flowers are pure white, sometimes displaying a gentle shade of blushed pink. Cosmos are a magnet to foraging insects and butterflies, including the monarch butterfly. The finely cut, cloud-like foliage resembles fennel leaves and is delicately scented. Flowers are followed by blackish, spiky seed heads (achenes).

Cosmos is an easy-going, rewarding annual that can single handedly fill a sunny slope, border or flower bed. It is perfect to animate romantic or cottage style gardens. Easy to grow even by beginners, this adorable plant with its feathery green leaves and naive flowers bring light and airiness to heavier blooms such as Dahlias. It combines well with perennial sage, Verbena bonariensis and chrysanthemums until the first frosts. It is particularly useful in new gardens mixed with poppies, love-in-a-mist or cornflowers. Its pretty blooms have a long vase life and are ideal for cutting.

Planting and care

Sow Cosmos seeds from March to May, at a depth of 3mm (0.1 in), in a fine compost and cover the seeds with a very fine pinch of vermiculite. Place the seed tray in a mini greenhouse at a temperature of 18-25°C or wrap it in a polythene bag. Keep the soil moist but not waterlogged.

Light promotes germination, which occurs 7 to 15 days after sowing. When the seedlings are large enough to handle, transplant them into individual pots with a diameter of 7cm (2.8 in).

Cultivate them in cooler conditions until the plants are sufficiently developed to be planted outdoors. When all risk of frost has passed, gradually acclimatize the plants to outdoor conditions for 7 to 10 days.

Plant them in full sun, in a moist, well-drained soil, spaced 45cm (17.7 in) apart. Pinch the tips of the shoots on each stem, during transplantation, to encourage branching and the production of numerous flowers.

Cosmos prefer a soil pH between 6 and 8.5, corresponding to the soil of their native habitat, the alkaline regions of Central America. They prefer full sun but tolerate partial shade. These plants are drought-tolerant once established, they are not prone to diseases but can be targeted by aphids. Spontaneous seedlings are common but not always true, without becoming invasive.

Planting & care advice

  1. How to sow cosmos

Cosmos are easy-to-grow, long-flowering annuals (Cosmos bipinnatus, Cosmos sulphureus) ideal for borders, beds and pollinator-friendly gardens. Follow these steps for reliable results.

When to sow
- Sow under cover: 4–6 weeks before last expected frost.
- Sow outdoors: after all risk of frost has passed and soil has warmed.
- In mild climates: sow in autumn for early spring display.
- For continuous flowering: sow every 2–3 weeks until early summer.

Seed preparation and soil
- No special pre-treatment required; seeds can be sown dry.
- Choose well-drained, moderately fertile soil. Cosmos prefer lean to average soil; very rich soil encourages floppy growth.
- Position: full sun for best flowering.

How to sow
- Surface-sow or cover very lightly: press seeds into soil or cover with about 2–5 mm of compost or soil.
- Spacing: thin/plant out to 20–30 cm (8–12 in) for tall C. bipinnatus; 10–15 cm (4–6 in) for compact C. sulphureus.
- Germination: 7–21 days at around 18–24 °C; keep soil just moist until seedlings establish.

Practical care
- Watering: keep moist while seedlings establish, then water sparingly—cosmos tolerate drought and too much water reduces flowering.
- Feeding: little or no fertiliser; a light low-nitrogen feed encourages blooms without excessive foliage.
- Pinching: optional. Pinch growing tips when plants reach about 10–15 cm to encourage bushiness and more flowers, but note pinching delays first blooms slightly.
- Support: stake taller varieties in exposed sites to prevent flopping.

Maintenance and problems
- Deadhead spent flowers regularly to prolong bloom period.
- Pests/diseases: generally trouble-free. Watch for slugs on young seedlings and powdery mildew in humid, overcrowded conditions.
- To save seed: let heads dry on plant until brown, then collect seeds and store in a cool dry place.

Quick tips
- Sow directly where plants will flower to avoid root disturbance.
- Use succession sowing for long season of colour.
- Mix varieties for different heights and colours to create natural, airy displays.

With minimal attention, cosmos will reward garden with abundant, long-lasting flowers attractive to bees and butterflies. Tips
