|Cardiocrinum giganteum (syn. Lilium giganteum)|
Propagation can be from autumn sown seed the plants taking around six years to flower. Offsets can be removed from the side of the flowering crown which dies in October and grown on or left to develop in situ giving an element of naturalisation.
In this month's RHS magazine I was interested to read about the new temperature guide to RHS hardiness ratings, all very interesting. The article made it clear that the RHS were going all out for the retailers to publicise the guide to the general public to encourage better understanding. Good luck with that then!
