Description
Celosia argentea cristata or Cockscomb 'Triangle mix' features a beautiful palette of warm shades ranging from yellow to red, orange and salmon pink. Their unique crested flowerheads are long-lasting and don’t fade over time making it an excellent cut flower, ideal for dried floral arrangements. This highly original, extravagant annual will bring stunning autumnal hues to flower beds and borders. Easy to grow in a sunny location in well-drained, cool soil.
Native to tropical and temperate regions of America and Asia, Celosia argentea ssp. cristata is a perennial herbaceous plant of the Amaranthaceae family. It is commonly known as Cockscomb or Woolflower due to its strangely-shaped flowerheads. This short-lived, frost tender plant is often grown as an annual in colder climates; it enjoys plenty of sun and rich, cool, well-drained soils. 'Triangle mix' brings together several fabulous varieties for an explosion of harmonious colours when in bloom, from soft pinks and oranges to bright yellows and reds. The flowering period begins in July and generally extends until September, sometimes until the first frosts depending on the sowing date. Plants measure approximately 70 cm tall when in full bloom. The single, unbranched, ridged stems bear long, triangular light green leaves with occasional reddish or purplish colouring. At the end of the stem is held a compact, fan-shaped flowerhead with a wavy, velvety appearance. It consists of tiny, petalless flowers with coloured bracts. Each inflorescence measures up to 20 cm in diameter and can last up to 8 weeks. After pollination, seeds are formed which germinate easily in light soil.
Cockscombs are spectacular flowers that bring a dramatic, extravagant note to arrangements and perennial flower beds. They look fabulous on the patio or balcony when planted in large pots or containers. They enhance the modest blooms of daisies and combine well with delicate cosmos flowers and starry blues asters. They look sensational when planted in groups of 3 to 5, surrounded by a carpet of low-growing ground cover plants such as Cerastostima plumbaginoides, Alyssum sempervirens or Ajuga reptans. Celosia is an excellent cut flower – avoid overfilling the vase and make sure to change the water often to prevent stem rot.

Planting and care
Direct sow from March to May in loose, well-prepared soil. Scatter the seeds in furrows, 2-3 mm deep. Leave 30 cm between each furrow. Water regularly to maintain soil moisture, especially during dry spells. Alternatively, sow in pots or seed trays at a temperature of 20-25°C. Use good quality sowing mix and cover with a fine layer of compost or vermiculite. Keep the soil moist but not soggy and make sure to give the seeds enough light to germinate. Germination takes 3-15 days.
When the plants are strong enough to handle, transplant them into pots. When all risk of frost is over, they are ready to be planted out in their final location.
Celosia is a heat-loving plant that likes nitrogen-rich soil. Choose a sunny spot in light, enriched soil. Make sure to not overwater the plants as this can cause root rot.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
