Bulbs: I am new to ALLIUMS, 1 by DonnaMack

Rouge,

They actually open at quite different times. When I was buying them, I wanted the longest season possible.

Allium oreophyllum blooms in late May. I use it to accompany my peony bloom time.

Allium caeruleum opens in mid-June, with Rosepoint Lace. The color is gorgeous, but it is somewhat insubstantial. You need a lot to make an impact, but it is very inexpensive. As you can see, it overlaps allium christophii, but christophii lasts much longer in bloom and the seedheads last for months. Please see the pic.

Allium christophii starts blooming in late May, but new ones keep opening for weeks, sometimes until the end of June.

Drumstick allium (sphaerocephalon) starts blooming in mid-July. It blooms for weeks because all of them don't bloom at once. And if you dig them up you will see that they reproduce like mad.

There is one I didn't mention because it is very difficult to find: allium ramosum (see pic). I found it years ago. It blooms in September, and for weeks. But it does seed like mad, so you have to watch it. But it is amazing - and almost impossible to transplant, unlike other alliums. I have purchased the seeds.

I'm going to send this and have a look at your site.

One more I should mention, because it was wonderful but the grass cutters kept chopping it: allium karataviense. Gorgeous foliage.

The ones that did not work for me were triquetrum (I fell in love with it in San Francisco, and it likes damp shade, but that's OK - it's invasive there) and allium roseum, which faded away after the first season and never returned.
