Gardeners' Notes:

Positive coriaceous On Feb 26, 2014, coriaceous from ROSLINDALE, MA wrote:

True 'Spring Beauty' is a little larger and more robust than the species.

It's also sterile, so it increases by offsets but not by seed. It would be the better choice where you don't want it to spread uncontrolled---for example, mixed with a variety of spring ephemerals and minor bulbs. If you want it to spread across your lawn, the species would be a better choice.

I wonder, though, how often what's sold as this cultivar may actually be just the species.

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!

We look forward to this "sign of Spring" every year. They like our neighborhood. Also the grounds of the nearby Henry Ford Estate are loaded with them each Spring.

Yes, these form delightful carpets of blue every April. The surprise is that in my yard, they seldom grow where I've planted them. Could the critters have had better gardening plans?

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.

Gorgeous! Beautiful blue!

I love to see it every Spring blooming!

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.

Positive ineedacupoftea On Mar 30, 2006, ineedacupoftea from Denver, CO wrote:

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."
