Bob Solberg 2008. Ruffled leaves, narrow at first and then widening over time. They emerge yellow in the spring and with age will move to chartreuse-green in our gardens. Too much sunshine and they will go the other way to white. The ruffled leaves create mounds that eventually produce purple scapes with lavender flowers. I always hoped they would maintain a bright yellow all season but guess I never found that right placement respective of sunshine.
