Arbutus,
genus of small trees and shrubs of the heath family, including the madrona
tree (Arbutus
menziesii) of California and Oregon, and the strawberry tree (Arbutus
unedo) of Europe. In the eastern United States a closely related genus
is called trailing arbutus. Arbutus menziesii is broadleaf evergreen tree,
up to 30 metres tall, usually with a crooked or leaning trunk that divides
into several twisting upright branches and an irregularly rounded crown.
Leaves:
Dark and glossy but pale underneath, 7 to 12 centimetres long, thick,
with a leathery texture.
Flowers: Dense clusters of urn-shaped white, waxy flowers drooping at
the ends of twigs in April or May. Fruit: The fruit is berry-like, 7
millimetres across, and bright reddish-orange, with a peel-like surface
texture.
Bark: The bark is thin, smooth, and reddish-brown, peeling in thin flakes
or strips to expose younger, smooth, greenish to cinnamon-red bark underneath.
Where Arbutus Grows: Arbutus is restricted to a narrow band along the
south coast and generally occurs within 8 kilometres of the ocean. It
is often found on exposed rocky bluffs overlooking the ocean.
Habitat: Arbutus is found on sites that lack moisture, such as those
with rocky or rapidly drained soils. Because it does not like shade,
it generally occurs in clearings or on open rocky bluffs with other
species such as Garry oak or Douglas-fir, oceanspray, Oregon-grape,
baldhip rose, and several herbs and grasses. The flowers have a strong
honey smell and are very attractive to bees. Fruit-eating birds such
as waxwings and robins frequently eat the berries.
Uses: Arbutus bark is very rich in a substance used for tanning hides.
The wood is heavy and hard, tends to
be brittle, and cracks when drying. It is used only for woodworking
in British Columbia.
Arbutus is the only native broadleaf evergreen tree in Canada. Another
common name is madrone, a Spanish word for the strawberry tree, of which
arbutus is a close relative. The Scottish botanist Archibald Menzies
first collected specimens in 1792 and described it as the oriental strawberry
tree.
Also known as the Strawberry-tree, Arbousier. This tree, of the Erica
family, is normally found on acid soils. Planted in gardens (even limestone)
it can reach massive size! The typical heather-like bell-flowers are
often on the tree at the same time as the ripening fruit. Although the
(edible) fruit looks a bit like a strawberry it is rather gritty and
tasteless. |
