Except for the dwarf perennials, most delphiniums need staking, as you can see on the photos. The plants bloom in late spring to summer, and the flowers are suitable for cutting.
Delphiniums are available in a range of sizes, from dwarf varieties to those with towering. Flower color includes blue, red, white, and yellow; however, the rich, clear blues are especially prized by many gardeners. I think that the white ones are beautiful as well.
Strolling along pretty flowers I've noticed some names of varieties: 'Clifford sky', 'Blue lagoon', 'Cassius', 'Conspicuous', 'Sandpiper'. The last one was white Delphinium. Take a look at these varieties:
I always wanted to have this plant in my garden too, 2 years ago I learned that Delphiniums are very difficult to grow from seed. So I bought a potted plant at the nursery and planted in that spring. Here is my delphinium (sorry, don't know the variety), now its seeds are ripen and I want to sow them in autumn.
