Crocosmia 'Babylon' (Montbretia)
Crocosmia 'Babylon' produces large orange-red flowers with warm yellow throats on arching stems, adding movement and bold colour to mid and back borders in late summer. The flowers are loved by pollinators and make strong cut stems too.
Reaching an established height of around 80–100 cm, crocosmia forms clumps of sword-like foliage and throws up branching sprays of bloom. It’s a reliable perennial that provides colour right into early autumn.
Plant corms in spring in full sun or light partial shade, in soil that is fertile and moist but well-drained. A sheltered position helps stems stay upright and extends the flowering display.
Water in dry spells during active growth, and feed in late spring for best flowering. After flowering, remove spent stems if desired, but leave foliage to die back naturally to feed the corms for next year.
Ideal for prairie-style borders, cottage gardens and large containers, crocosmia pairs beautifully with grasses and late-summer perennials.
