Allium, Ornamental Onion, Ornamental Allium 'Purple Sensation'

One of the only bulbs the squirrels won't dig up, these plants are great. I am planning on putting in more this fall.

Spherical masses of bright purple flowers on a straight stalk (not over 2' tall in my experience). Blooms in mid-May here in Boston Z6a. ...Read MoreBlooms before A. christophii without overlapping. Leaves begin to go dormant during flowering.

These are more modest in scale than A. giganteum and the statuesque globe hybrids. They're also much cheaper and much more inclined to perennialize.

Their most important needs are full sun and good drainage. Not usually attractive to critters.

I've seen these increase a little, but not as much as I'd like. A fine border plant, this is one of the few alliums that can tolerate shading by other close-growing perennials. They should be planted in groups, and with abandon. (Don't worry, they're inexpensive.)

grows at 9000' in Colorado mountains, although may die out with a very long, wet spring

I love Allium Purple Sensation!

I planted 10 last Autumn just to try them (they're already multiplying . . . 11 have come ...Read Moreup). They are spectacular, opening one at a time, then they keep growing after they open, & now they're huge & still growing!

They're growing right in front of some Salvia Eveline that I planted last Spring (another experiment) & the combination of the Purple-Violet Alliums with the Light Pink Salvias is beautiful & eye-catching.

We have all sorts of wild critters in our area & though we thoroughly enjoy them, I normally have to resort to things like "Liquid Fence" on many of the plants. . .but none of the critters have any interest in the Alliums which is another bonus!

I will definitely be planting more of these gorgeous Alliums in Autumn.

I also find the Alliums still very interesting to look at even after the blooms are gone so I leave them standing in my garden.
