Thanks for the posts pitimpinai. Just today I found a nursery that does stock it. (Plus I do have 20 coming from an on-line source from an order I placed back in early August...hopefully coming in before the end of the month). I saw it for the first time this past early summer, when they were past their prime and I was still so impressed. I have several other alliums but they are mostly the very tall varieties. I liked the fact that "Christophii" was significantly shorter. pitimpinai, can you tell me a bit more about it....how tall does it get for you? I take it that it does reseed in the garden (I have not found that with any of my other alliums).

Contrary to the previous poster's opinion I would plant all your 7 Purple Sensations as a one cluster. You'll have a good display the very first year vs 1-2 'no impact' alliums here and there. Yes, they multiply and seed pretty freely, so after the second growing season you'll have enough to divide and move to another areas. Beware that PS foliage dies and look very ratty well before it start flowering, so you may want to plant them where it will be hided. In a picture below (mid-May), dying foliage of alliums is hided by still good looking foliage of daffodils that were planted in a same hole, but bloomed much earlier. Same spot three weeks before (you may see alliums flower heads between daffs):

Rouge21, you will love your Allium 'Millenium'. It is a beautiful, very low maintenance and extremely easy to please garden plant. And yes, the flowers do not form seed but produce huge amounts of nectar that bees and butterflies will flock to. I am also a bit Allium obsessed and I have discovered that like the smaller rhizomatous types and smaller bulbous types best of all. When in growth mode, the large globe alliums from Holland have the tendency to steamroll and suffocate many of my more delicate perennials so I have been removing them. Allium cristophii is my favorite of the larger bulb types. The foliage is somewhat narrow and relatively well-behaved, and it is reliably perennial for me. It produces hundreds of grass-like seedlings every spring, but none of them seem to return the second year. I wish it would spread all over. I love it! I also love the drumstick alliums. This plant returns each year from the bulbs, but does not appear to set seed in my garden. I also wish it would spread all over. The very narrow, grassy foliage mixes very well in a perennial border and barely takes up any space. A new bulbous type for me this year is Allium obliquum. The plants are gorgeous and relatively compact, looking like a very elegant and tidy garlic. The twisting flower stems are striking and delightful. I would grow it for the flower buds alone, and I haven't even seen the flowers yet, lol! And it is very easy to start from seed!

I have a few of the twister types that are very well behaved. Bought them several years ago from High Country Gardens. I just looked but they don't have them anymore. I also have 'Summer Beauty' which has clean foliage all season long. Highly recommend! I had some unknown volunteer for several years at my previous home and liked it so well I brought it with when we moved. It's blooming now. Green go, love your use of the spent flower heads. I always keep mine up even after they're brown and toasty because they're just so neat looking.
