I love the gorgeous form of this unique flowering plant that grows from corms (seed as well.) Beautiful, deep red bloom in July, when garden is at peak. Divide it every 5 years. Dig down about a foot, use a fork. The corms are created each year on top of each other. They flower best if slightly compacted. So just divide a large root ball in two. The division will invigorate it. Plant deep to access moisture. Don't cut back the foliage if you are not moving them.
