Heuchera (pronounced Hew-ker-ah), also commonly called Coral Bells or alum root, are known and planted mostly for their bright, colorful leaves that bring jewel tones to the garden.
My friend got me hooked (heuched?) with a start of basic coral bells, and now I can't stop. Fortunately, they make great companions for perennial geraniums, my other current "can't pass a new one by" plant. Great article, and a nice selection of photos!
