Started these bulbs from a freebie packet. They are dainty and bright blue. I have never kept them in a moist place. They are in a somewhat shady area growing alongside the arum plant. I always look forward to seeing them bloom. Live in Ft. Mitchell, KY.

I bought small bulbs about 10 years ago for a flowering plant that was called "muscari". I planted it, it has grown, not over-abundantly, but it is hardy. I live in New Brunswick, Canada. It never gets watered, it has basically grown on its own, wild, since that time. I've never split it or moved it. It is beautiful and a wonderful bright spot on a brown lawn, it grows that early. I've never heard it called Siberian Squill, only Muscari-- that's what the package said!

I love scilla and especially this cultivar. Amazing and unusual shade of blue - bright yet intense, neither dark nor light. It makes a carpet of blue over time. Blooms last about a month - all April here.

I love blue, and this flower is truly blue! It fills in more each year. I interplant it with Ceratostigma plumbaginoides, which comes up when the squill is finishing up and provides blue flowers from summer to fall.

This popular cultivar, is, in fact, an improvement over the species. When comparing them, 'Spring Beauty' is a slightly deeper blue (to begin) but mainly that the larger flowers open up wider and are outward facing. (So as to lend more viewable surface-area to color.) Not a cultivar to be chosen if the pendulous flower form of S. siberica is what makes your happy.
Just a perfect true blue for a big "splash" or a mass-planted "ocean."
