Neal, I really like the Scilla siberica - haven't seen that one before. I started a small Galanthus collection last fall, getting a handful of bulbs of five different kinds that were available at Brent and Becky's. By the time I ordered though, 'Floro Pleno' was already sold out so I'll get my order in earlier this year for it. I would love to start getting more variety from the sources that steve_mass mentioned, but they are pretty pricey so will likely only get one or two a year. I love the idea of a large Galanthus collection planted in the garden area I call the 'Fern Bank'.
