Donkeytail Spurge

This sprawling evergreen perennial belongs to the euphorbia family. Growing about 8 inches tall, it sends out sprawling branches covered with waxy, blue-gray leaves. The sessile foliage is only about an inch long and is tightly clustered down the stem in a beautifully congested spiral.
In early spring, small, yellow flowers appear in terminal clusters at the ends of branches. These petalless affairs are called cyathia, and they’re clustered inside a bowl-shaped structure consisting of two yellow, cup-shaped bracts. The cups are ¾ of an inch across, but they’re clustered together to form an inflorescence that’s 3-4 inches wide.
