Fritillaria imperialis

My success with F. imperialis is growing it under a Russian Medlar tree.
It has been there for twenty years and flowers every third or fourth year. I believe the soil is kept dry by the tree roots.
Other places I have tried it have been a failure.
Jane has got it. Needs to be dry in the summer.
