Nevin’s barberry. Unusual evergreen with small, tough ashen-colored leaves, often with rosy margins and always armed with intimidating spines. Growing 3-12’ with an almost arching form, it is well used as an attractive barrier plant bearing bright yellow springtime flowers and translucent red berries that attract western blue-birds mid-summer to fall. A native treasure with an astonishing range of tolerances, mature plants require only occasional water. Hardy to 0F and below. Southern California.
