Having said that, I'd better give you Rannveig's instructions here:
FRITILLARIA DAVIDII Rannveig Wallis’ CULTURAL HINTS
This unique dwarf species comes from SW Sichuan, China where it grows on north facing hillsides in the company of ferns under birch shade in leafy soils. A companion plant is sometimes Corjydalis flexuosa so it enjoys the same conditions and, in fact, will grow outside in woodland.
In cultivation: we repot the bulbs in early June in an equal parts: leafmould, perlite, JI no. 2 mix, water them and leave them outside in shade with frequent watering/rain all summer even though dormant.
We have always used plastic pots as they seem to stay a bit moister. The leaves appear in late October when, in order to protect them from molluscs, which love them, we plunge them in a sunny alpine house for the winter. They still need watering at this point. Flowering takes place in March and the leaves go dormant rapidly after this. Other growers have successfully used a moss peat/pulverised bark mix. The emphasis should be on a light airy compost which is not too acidic.
Remember the leaves do not resemble those of other fritillaries since they have branched veins and are all wrinkly!
