I'm very happy that it's a perennial! I didn't know there were other types of Delphiniums besides the tall spiked ones. I planted a yellow snapdragon beside it so they can compliment each other. I will post a pic after it gets a little taller.

I bought 2 of these plants. They were small. Only one lived and is doing ok. Is only about 8 inches tall and has no flowers

For anyone looking for this plant, I just found it today (5/21/10) at my local Lowes (Lebanon, TN) for $3.33 each. I bought two and will put them in my garden tomorrow morning.
