Gardeners' Notes:

Leopard Lilies grow wild in Northern CA. They can be found in bloom in the shadier areas around the foothills in mid summer. They are plentiful in parts of a nearby wilderness park that are not often frequented by humans, and can be found in sandy loam soil in part-sun to full-shade areas. I've always seen them near the creek, but not necesarily in moist soil. I think they prefer the higher humidity found near the creek, as Northern CA is very hot and dry in the summer months when they are in bloom, but the soil I have found them growing in is not particularly moist. I have not tried to transplant them from the wild, but I do know a nearby native plants nursery often has them for sale. The flowers are amazing and a photograph cannot do them justice :).

I believe this lily is highly endangered in it's native Californian habitat.
I planted some out last year- after handling all those oriental bulbs, it's weird to see the stoloniferous ones produced by these turks cap types! They get half day shade in an underplanting situation and seem to be happy enough, though some say this is a temperamental beast. They flower from a very small size which is great!
Just fabulous once they're established and monstrous, with huge candelabras of bicoloured, spotted blooms, and freely offsetting too.
If you can get hold of it, give it a try. Lily societies often have them for sale.
*Update- There are apparently many varieties of this species and Ive been trying to work out which one I h... read more
