One of my Favorite Yellow TB iris. She is my second favorite after 'Heartbeat Away' TB iris, which is almost identical to her in everyway with the same yellow color and long bluish- purple space age horns, except for the fact that Skyhooks TB iris, is not as bright as Heartbeat Away, and about two inches shorter. Also Skyhooks TB iris is not to be confused with Skyhooks ufo daylily which is lavender pink and shares the same name but of coarse is a daylily, and not a tb iris. I am currently growing Heartbeat Away and Summer Radiance for yellow iris in my yard, but eventially want to get Skyhooks as my third and final yellow TB iris..peace.mike

The beard turns up for about 1/2 it's length. Maybe 2/3 actually do it. Pretty and interesting.
