Taxonomy:
Genus:
Arbutus
Species:
A. menziesii
Common Name:
Pacific Madrona
Description:
Arbutus menziesii is an evergreen tree about 10 to 25 metres (33 to 82 feet) in height, but in the right conditions up to 30 m (98 ft). The trunk is usually about 60 centimetres (24 inches) thick. The thin bark is a rich orange-red, and when mature naturally peels away in thin sheets, leaving a greenish, silvery appearance that has a smooth satin sheen. Older trunks are gray-brown near the base.[5] Individual trees can live for over 300 years.
The leaves are thick with a waxy texture, elliptical, 7 to 15 cm (2+3/4 to 6 in) long and 4 to 8 cm (1+1/2 to 3+1/4 in) broad, arranged spirally; they are glossy dark green above and a lighter, more grayish green beneath, with an entire margin. The leaves are evergreen, lasting a few years before detaching. Some second-year leaves turn orange to red and detach in the autumn. In the north of its range, wet winters often promote a brown to black leaf discoloration due to fungal infections; the stain lasts until the leaves naturally detach at the end of their lifespan. In spring, the tree bears sprays of small white to pink bell-like flowers,and in autumn, red berries.
Range:
It is native to the
Pacific Coast region of North America from British Columbia (chiefly Vancouver Island and the Gulf Islands) to California. They are mainly found in Puget Sound, the Oregon Coast Range and the California Coast Range but can also be seen scattered on the west slope of the Cascade and Sierra Nevada mountain ranges.
Arbutus menziesii exists in a few relict strands in southern California, believed to be survivors from the last glacia age. Here, populations are found on Santa Cruz Island, the San Gabriel Mountains, and south to the Santa Ana Mountains, the Agua Tibia Mountains and Palomar Mountain. The southernmost population is located on Roderick Mountain overlooking the canyon of the San Luis Rey River in San Diego County, where several hundred are found. George Bishop Sudworth reported a few shrubby individuals of Pacific madrone from the Santa Monica Mountains in Los Tuñas Canyon, but this population may not still survive.

Habitat:
It fares well in dry and rocky sites, is tolerant of salt water, but fairly intolerant of shade.
