Sown from seed, it's been the only delphinium of dozens that has survived the climate and pests of my zone 6b garden. After I started liming the garden as well as the lawn, it turned from unremarkable white to vivid blue like joesinay's pics.

In our climate here in the Pacific Northwest, this is one of the most amazing plants anyone can have in his or her garden. The blooms grow 4' to 5' and the colors are amazing. If you cut the bloom right as it begins to fade, often it reblooms. My mom had me grow two dozen for her last year and she still goes on and on about them. Luckily, they are even better the next year. (They bloom the first year from seed.)
