I planted this delphinium last summer; this was my first attempt to grow these supposedly fussy plants. I got several blooms, cut the stalks down, and it rebloomed. The flowers are long lasting, so I would say the bloom period covered a majority of the summer. The stems are indeed brittle and broke off in some wind; I have staked it much more securely this year. Despite many people telling me this would likely not come back, it surely did and is large, full, and already blooming beautifully at the beginning of June. This variety is a really stunning deep purple and blue combination. I do bait for slugs and I put down some time-release fertilizer this spring; because of good rainfall I have only watered it a few times. It may or may not return again next year, but if it doesn't, I will absolutely go buy another one!
Update 2011: it's back, bigger and better than ever.
Update 2012: it's back, and at least three of the flower stalks are now 7 feet tall. It's fabulous!

I grew my plant from seed, and though the flower color is the same as those pictured here, the flower stem was not full but lanky.
My pagan purple delphinium produced one stem of flowers. It bloomed for a few weeks and was absolutely extraordinary in beauty. As it obtained 5' I failed to stake it well enough and a bird landed on the stem and snapped it off.
This flower had violet inner petals with deep blue outer petals.
Great plant! Bought it in a 3" pot, it grew huge and bloomed its first year, survived the winter just fine, and bloomed even better the 2nd year... and it really is a full 6 feet tall (not 36-48" as indicated on this page)! I had problems with aphids on 'Magic Fountains' delphinium but not on this one (so far). It requires some staking because of its height, but the stems are fairly rigid and do partially support themselves. After blooming, it had new growth coming up, so I cut the old stalks back to the ground. It is currently regrowing and will probably rebloom.
This plant has been said to grow in the following regions:
