They bloom in late winter, early spring. They will get to be anywhere from 12 to 24 inches tall. Short lived in flower arrangements, but pretty. Bulbs are likely to be found in next year's bulb catalogs and on-line. I doubt that you would have much luck finding bulbs right now.

Last fall I bought beautiful bulbs of this species at the Riverbanks Zoo bulb sale in Columbia, SC. They were big bulbs with small bulbs attached. I planted them right after I got them in Nov. and they began to bloom in mid.Feb. I was puzzled by the name though because I had read on the internet that the Summer Snowflake, L. aestivum was a late bloomer and it was the vernal one that was early spring but mine were labeled L. aestivum and they bloomed in Feb. which is what I wanted. They got about 8-12" tall. This may not be near you but they have excellent quality bulbs, much better than you get from a catalog, in my experience.
