The family Ericaceae consists of shrubs, tress, and perennial herbs, many of them familar as garden plants: rhododendrons, azaleas, heaths, heathers, and blueberries.

Manzanitas are variable in size, ranging from prostrate bushes a couple of feet tall to shrub-trees 10 feet high or taller. They all have thick, leathery leaves, smooth or a bit raspy, pointed-oval, on short petioles, blue-green to grey-green in color, and 1 - 1.5 inches long. The bark is the most distinctive part of the plants, with its famous Manzanita red-brown.


The regular flowers usually have a 5-lobed calyx and a corolla of either 5 lobes or 5 separate petals, with 5 or 10 stamens.

Flowers show in spring as masses of mostly terminal white to pink urns, maturing into reddish berries. Berries are mealy-bland in taste, but with a little tartness.

The fruit is fleshy or dry, and usually partitioned into 5 seed producing divisions.
The genus Manzanita has a high degree of endemism and over 80+ taxa. Several species extend out of the California Floristic Province, including the circumboreal A. uva-ursi. Manzanitas are important members of a number of plant communities, especially chaparral. The word manzanita translates as "little apple".
