I love snowdrops, but I want the bloom season throughout the winter, rather than collecting distinct types. Currently, these Galanthus reginae-olgae from the PBS bulb exchange are blooming now. I don't know when they would bloom when they get into the ground (here in zone 7/8 near Seattle), but probably with a variety of species and accessions from the species, one could have an extended season of blooms, weather permitting.
