In a front bed, white irises and purple irises bloom every spring. The bulbs were planted by the previous owners of our home. I've seen pink irises around town and thought they are so pretty.

P.S. Here's a great video on how to plant these bulbs (oops, I think I need to go redo our planting job): How to Plant Iris: Step-by-Step Gardening
