Welcome, Rebekah!
I bet you're going to want to spend some time looking at the database to find plants you want. Here's the stats and info about 'Chasing Rainbows':
Tall Bearded Iris (Iris 'Chasing Rainbows') You can go crazy finding and creating a "want" list (I have), but I know of no better way to learn about the huge variety of irises available! Good luck selecting choices! People here can tell you how they grow and how they increase in their gardens. You might want to update the settings to put your general location and zone in (you'll see mine at top right) so people here can help even more!
