Golden Angel Japanese Shrub Mint. This is a little-known shade perennial in the U. S. I was first introduced to this genus in Japan where it is native. This selection has bright golden-yellow leaves when they emerge in spring which light up the woodland garden, and with this selection it gets to about 24" high. Spikes of soft yellow-white flowers arise over the foliage each fall. This makes a great combination with Hosta. It prefers uniform moisture and good organic matter to thrive.
