Cardiocrinum giganteum

Giant Lily, Lilium giganteum

This astonishing hardy perennial makes a fascinating talking point. The tall stems of the Giant Himalayan Lily tower to 2.5m (98") or more in an awe-inspiring display. With maturity Cardicrinum giganteum is topped with a crown of white Lily-like blooms from June the July. The trumpet shaped flowers have a powerful fragrance, attracting plenty of pollinating insects, before they are replaced by interesting oblong seedpods in late summer. The Giant Himalayan Lily may take 3 or more years to flower but is well worth the wait.

This fascinating plant is monocarpic, meaning that it dies after flowering - but don't be put off, it leaves behind offsets that will flower in 3 to 5 years time. Cardiocrinum giganteum is a most unusual plant that will add a real focal point to lightly shaded exotic gardens and woodland borders. Height: 250 cm (98"). Spread: 45cm (18").
