Hi Bruce,

I didn't know that Phaedranassa tunguraguae x Eucrosia mirabilis were that closely related enough to hybridize, that's pretty amazing. Do you have a pictures of the seedlings?

Subject: [pbs] Growing Eucrosia sp

Like so many South American bulbs, there is so little information available regarding the natural growing environment for the various species of this genus and their growing needs under cultivation.  I am growing a couple of species at the moment here in Melbourne, Australia in my unheated greenhouse where winter temperatures are down to approx 5C.  I have flowered E mirabilis and have near flowering size E aurantiaca (seeds from
PBS) and 2 year old seedlings of a E aurantiaca hybrid.  I also have seedlings of the same age of my own cross of Phaedranassa tunguraguae x Eucrosia mirabilis.  E bicolor doesn't seem to like the cold here unfortunately.

My primary query is whether plants of the genus should be grown with their bulbs partly exposed, the neck at the surface of the growing media or fully buried (if so, what depth)?
