Not the most vigorous grower, but it is easily the prettiest medium blue iris I've grown (or seen).

Planted it in 2006, it bloomed beautifully in 2007. I can't wait to see it in 2008. Magnificent iris that seems perfectly adapted to our 5a, dry, cool climate.

Beautiful iris, growth is normal here in zone 6b.

Positive MikenMyrtle On Jun 30, 2006, MikenMyrtle from Myrtle Beach, SC wrote:

I saw a picture of Sea Power three years ago and wondered if it could be as beautiful as that particular photograph. It bloomed for me this spring, and my assessment is "yes." The color of the flower often didn't come out as deeply blue in several of my photos of it, but in real life it really is this pretty.

I would add, however, that it is not a terribly fast grower here, though this is stated very honestly by Keith Keppel, the hybridizer, in his description--he states that it takes a little time for it to get established, but it is worth the wait. I agree!

Sea Power was the top Wister Medalist in 05, and has been announced as the 2006 Dykes Medal winner.

The beauty of Sea Power isn't caught by photos. It catches the light and becomes translucent at the top of the stands. If I had to choose one 'blue' Iris, Sea Power would be it.
