Sempervivum SuperSemp
SuperSemps were introduced last year, and now have two new colors (Emerald is pictured). These low-water varieties are excellent in containers, garden borders and xeriscape landscapes. They have super fast production — six weeks from 72-cell to 4-inch pot and then six weeks from 4-inch pot to 1-gallon container. And rosettes are 8 inches!
