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.

I am wondering what you did about transplanting your allium. I just dug mine up and put them in a paper bag as the instructions said on my google search. No one responded to your question on that and I didn't find much info on it online so I am hoping for the best. You may have discovered however, that the foliage does dies down pretty quickly and disappears so the foliage doesn't look huge for all that long.

I order from Scheepers every year. Globemaster lasts the longest but seems to be the most expensive and also seems to shrink in size every year. I will divide this year but I probably really need to fertilize. But anyway I would recommend them. Second I like Purple Sensation. They are cheap and very pretty. Darker than liatris but not dark purple. Buy as many as you can plant. Plan some perennials around them so their dying foliage is masked. Alliums are a great buy.

I just bought Purple Sensation and Gladiator Alliums along with oriental lilies. I have posted a similar question on the lily forum since the same problem applies. I planted some Sphaerocephalon Drumstick alliums last fall and was not impressed: they grew about 3 feet tall and the stems were so weak they just flopped. I'm hoping these others will have stronger stems. However, the garden is currently STUFFED. I have some dahlias and annuals in there to give me fall color. It's a new garden and I had space to fill temporarily. Most are smack dab where I want those alliums and lilies. I was planning to buy in spring but I succumbed to temptation (the price was right!). I consider myself pretty tough but I cannot willfully kill a dahlia (not when they're blooming their heads off like that...!). Can I wait to plant the bulbs until first frost, then dig the dahlias? Or will they have insufficient time to make roots? I'm in Zone 5, Chicago north suburbs. In a pinch can I hold some til spring? In case the weather becomes too horrible to be outside after the frost. I do have space in a holding bed if that is a better option. Also, what kind of width does the foliage take up for these? I want them in thick clusters. I assume the leaves can overlap each other. I have 4 Gladiators and 10 Purple sensation (these PS probably I will split up into 2-3 different clusters.) Do the bloom times overlap on these or are they different? That will make a difference in where I plant them. Thanks!
