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.

The trumpet shaped flowers have a powerful fragrance, attracting plenty of pollinating insects, before they are replaced by interesting oblong seedpods in late summer.
