Calochortus sp.

Polygonum x bohemicum - an exotic invasive pest species frequently misidentified as P. japonicum

Thanks! I love the Calochortus. I want some! It looks like Calochortus macrocarpus.

Not adapted to conditions on this side of the mountains. There was a garden form with yellow flowers being sold locally awhile back but it seems to have come and gone quickly. Possibly it was more tractable than usual. New introductions coming from one or a few suppliers may be dropped quickly for reasons other than the plant being hard to grow - I found the new cherry red tulip with the blue interior markings to be quite good yet despite special promotion with posters etc. by the introducer and supplier it too seems to have disappeared after only a few years. I've forgotten the cultivar name and when I have asked about it at local outlets (still buying from the same company) have gotten blank looks. It had a forgettable cultivar name like 'Spring Beauty' but you'd think considering the promotion it got and its unusual characteristics that it would have made more of an impression on someone working with it only a year or to beforehand.
