Iris Forrestii

Distinguished by its lemon-yellow flowers with reddish-brown veins and markings on the falls, Iris forrestii, a member of the normally blue Chrysographes subseries, makes a superb companion with the black form of Iris chrysographes. A rarely offered clumping species from China, Yunnan, Sichuan & Burma, it grows in moist sites flowering in early summer, and is easy and non invasive in the border.
