Posted by springcolor (Washington State - Zone 7a) on Aug 23, 2014 6:49 PM concerning plant:

This plant has three seasons of color. Spring growth is flushed with pink, with the variegation. In summer the stems turn a amazing bright purple, and in fall you have the seed pods. Needs good drainage and at least half a day of sun. Full sun is better.
