Am I lucky or what? Dark plum-colored shamrocks the size of your palm. Slender, celery green stalks 12 to 18 inches tall. Clusters of blush pink, lily-shaped flowers. It took Proven Winners’ plant breeders’ years to make me this gorgeous, not to mention extra healthy and easy to grow. Just remember that sun scorches my shamrocks, so please plant me in part to full shade.
