The Purple Sensation alliums seem to do well here. I've noticed the Globemaster and Christophii have diminished in size over the years but they still return. Globemaster is now about the same size as my Purple Sensation, both the height and the size of the flower ball. It's too bad the foliage is already dying when the alliums bloom, but that is their nature. I understand there are a few varieties that hold their foliage fresh while blooming, Karativiense is one of them, but it requires excellent drainage to do well.
