A show stopper when in bloom.
1m x 1m
This deciduous bulb grows to 50cm x 50cm in the sun. It is frost resistant. The sprays of pink flowers occur in summer and it is a show stopper when in full bloom. As it occurs in wetlands and along our rivers so it is suitable for a bog garden or near a water feature. Burning in winter promotes flowering. If you have clay soil then dig in lots of organic compost as they are heavy feeders. The name is derived from the Greek 'diorama'=a funnel which refers to the shape of the flower.
