Description

A clump-forming crocosmia that sends up arching stems packed with orange-red, tubular flowers with a yellow throat in mid to late summer. The sword-like foliage adds structure through the season, while the blooms bring strong colour when many borders start to fade. Plant in groups for best impact in mixed borders, gravel gardens or large containers. Crocosmia grows best in soil that stays moist but drains well; water in dry spells for better flowering. Give it full sun or light/partial shade (it may flower less in deep shade). Over time the corms can multiply into a clump, which you can divide to keep it tidy or to spread around the garden.

Also known as: Crocosmia, Montbretia, Crocosmia × crocosmiiflora ‘Carmin Brillant’, Crocosmia ‘Carmin Brilliant’ (alternate spelling), Crocosmia ‘James Coey’

Key Benefits

• Mid to late-summer flowering for weeks of vibrant colour.
• Orange-red blooms with a contrasting yellow throat.
• Clump-forming habit – great for repeating through borders.
• Works well in full sun or light/partial shade.
• Moist but well-drained soil gives the best flowering performance.
• Excellent vertical texture from sword-like foliage.
• Great for mixed borders, “tropical-style” planting and large containers.
• Can be divided every few years to refresh clumps and create more plants.
• Reliable perennial in many UK gardens (see growing info below).
• Supplied as dormant corms – easy to plant and store briefly if needed.

• Pack size: 10 corms
• Flower colour: orange-red tones with yellow throat

Pollinator friendly: Crocosmia flowers are nectar/pollen-rich and are known for attracting bees and other pollinators in summer. Butterfly visits can vary by garden and weather, but this is a strong choice for adding late-season forage.

Best companions to plant nearby (great colour + shape contrast): Dahlia tubers, Canna rhizomes, Gladiolus corms, Agapanthus, and Alliums for earlier interest. Salvias also pair beautifully for a long summer display.

Growing Information

• Flowering time: mid to late summer
• Height: approx. 50–80cm (can reach around 1m in flower)
• Position: full sun to partial shade (avoid deep shade for best flowering)
• Soil: moderately fertile, humus-rich, moist but well-drained

Planting Guide (simple steps)

1. Plant in spring once the soil is workable and frost risk is reducing (typically from March onwards).
2. Choose a sunny or lightly shaded spot with moist, well-drained soil.
3. Plant corms about 10cm deep, spaced 7.5–10cm apart (plant in groups for a clump effect).
4. Water after planting, then keep lightly moist during dry spells.
5. After flowering, allow foliage to die back naturally to feed next year’s corms.
6. Divide congested clumps every few years to maintain strong flowering.

Good to know

• This cultivar has the RHS Award of Garden Merit (AGM).
• Crocosmias do best where soil retains some moisture in summer (very dry soil can reduce flowering).
• The name “Crocosmia” comes from Greek words linked to a saffron-like scent from dried flowers.
