Eriogonum fasciculatum (calif buckwheat)

California buckwheat. This common shrub is native to the southwestern United States and northwestern Mexico, where it grows on scrubby slopes and in chaparral and dry washes in a number of habitats. 

The leaves grow in clusters at nodes along the branches and are leathery, woolly on the undersides, and rolled under along the edges. Flowers appear in dense, frilly clusters which may be anywhere from a few millimeters to 15 centimeters wide. Each individual flower is pink and white and only a few millimeters across. This plant is particularly attractive to honey bees and is a good source of nectar over many months in drier areas.

tough and easy to grow, even in very dry conditions. Plant in a well draining sunny site. It shouldn't need supplemental water after established, but it will tolerate occasional summer water better than most extremely drought tolerant California natives.

 hardy to 0 F
