I planted mine last spring and it is about to bloom. I have it planted close to an ugly box that we have to have. It hides it nicely and I do not need to stake it. It is a keeper that is easy to take care of.
I have to add my non staking part. The Flower got so heavy that it could not support itself. I tied it around the ugly box :).

Great delphinium! Comes back every year so far (3 years now). I have the Guardian Mix (it comes up light blue, dark blue, and lavendar). It is beautiful! Blooms all summer and reblooms if you cut the dead stalks down. I have mine planted in heavy clay with no wind protection. I don't even need to stake it. It stays up well, maybe one stalk will fall over, that I stake.

This is just returning for it's second year; so we shall see. From plant tag: Clump forming perennial produces dark green, lobed foliage and tall spikes of lavender summer to fall blooms. Stems are thin and strong, which makes this plant an excellent cut flower.
