Arbutus is a genus of at least 14 species of
flowering plants in the family Ericaceae, native to warm temperate regions
of the Mediterranean, western Europe, and North America.
North American members of the genus are called Madrones, from the Spanish
name madroño. The European species are called Strawberry Trees
from the superficial resemblance of the fruit to a strawberry; some species
are sometimes referred to simply as the "Arbutus". Curiously,
the name "Madrone" is used south of the Siskiyou Mountains of
southern Oregon/northern California and the name "Madrona" is
used north of the Siskiyou Mountains according to the "Sunset Western
Garden Book". North of the Canadian border, the name "Arbutus"
is commonly used.[1] All refer to the same tree, Arbutus menziesii, native
to the Pacific Northwest and Northern California regions.
It is not classified as an evergreen since its leaves fall off, nor is
it considered a large shrub with an adult height of 5-25 meters. It has
red or brownish bark that peels off each year as the tree grows, while
the trunk of the tree is smooth to the touch. The leaves are spirally
arranged, oval to broad lanceolate, with a serrated or entire margin.
The flowers are bell-shaped, 5–10 mm long, white, yellow or pink,
and produced in racemes or corymbs. The fruit is a rough-textured red
or orange-red berry 1–2 cm in diameter containing yellow-flesh fruit
with numerous, very small seeds; the fruit is edible but has minimal flavour
and is not widely eaten. The fruit will dry out and turn brown with prickles
like burs that latch onto larger animals for migration to new areas.
A recent study which analyzed ribosomal DNA from Arbutus and related
genera suggests that the Mediterranean Basin species of Arbutus are not
very closely related to the North American species, and that the split
between the two groups of species occurred at the Paleogene/Neogene boundary.
Arbutus is a great fuelwood tree since it burns hot and long. Many North
West states in the United States use the wood primarily as a heat source,
as the wood holds no value in the production of homes since it doesn't
grow in straight timbers. |
