We have Sternbergia lutea. Plants came from Tblisi Botanical Garden;
Consevation Section. Jim Ault has tried to cross-pollinate the two dozen
or so plants without success. We have attributed the failures to our
harsh winters but perhaps there is another reason?

Ben Zonneveld mentioned something which might be the answer to a
which has long puzzled me. He mentioned a triploid Sternbergia lutea.


I've never known Sternbergia lutea to set seed. 


I have long suspected that the Sternbergia lutea of gardens is triploid.
furthermore I have often wondered if it is one of those plants of garden
origin which does not correspond exactly to any known wild plant. 


So here is the question which arises: are there any populations of the
broad-leaf form of Sternbergia commonly known as S. lutea which set
which correspond to sexually reproducing populations? 


Did this broad-leaf garden form arise as a hybrid between a narrow
form such as the ones often called sicula and some other broad leafed
species such as S. clusiana?
