About Morro Manzanita (Arctostaphylos morroensis) Arctostaphylos morroensis is a species endemic to California, where it is native to a very limited area of San Luis Obispo County and northern Santa Barbara County, from the vicinity of Morro Bay to Santa Maria. It is a spreading shrub, reaching up to 4 meters in height but usually less, and generally staying wider than tall. It has shreddy red-gray bark and whiskery bristles on the smaller branches and twigs. The leaves are oval-shaped and slightly convex, dark green on the upper surface and duller gray-green beneath. Plentiful flowers hang in dense clusters on short pedicels during the winter months. They are usually very light pink, urn-shaped, and hairy inside. The fruits are fuzzy red drupes each about a centimeter wide. This is a plant of the sandy coastal cliffs and beach chaparral. It is listed as a Threatened Species on the federal level and is on CNPS list 1B.1. It is also cultivated as an ornamental.
