About Pink Spineflower (Chorizanthe membranacea) Chorizanthe membranacea is a species of flowering plant in the buckwheat family known by the common name pink spineflower. It is native to Oregon and California, where it is widespread and in some areas quite common. It can be found in a wide variety of habitats. This herb grows erect to a maximum height near one meter. It is woolly in texture and most of its parts may bear a pink tint. The leaves are mostly linear in shape and they may occur along the stem as well as at the base. The longest may reach 5 centimeters. The flower cluster is a dense cluster of flowers, each surrounded by a unit of six fused leafs which are generally white to pinkish in color. The leafs are tipped with hooked awns. The flower itself is just a few millimeters long, white to pink, and quite hairy. There are sometimes small flower clusters located in the cauline leaf axils along the stem. This species is easily distinguished from other spineflowers by its relative abundance of leaves, its height and upright habit, and the fusion of the leafs of the involucre into a continuous body.
