Arroyo WillowArroyo Willow can
range in size from ten to thirty feet. It is a many branching large shrub or tree
that grows as wide as it grows high, and would thus require a large area near
a stream or moist area. It can grow in sun and shade. It is deciduous, with the
leaves turning yellow in late fall. Female and male trees are separate, and produce
catkins in early spring usually before the leaves grow. Small cottony seeds are
dispersed by wind, and can collect in areas that do not have a through-draft.
Arroyo Willow is common throughout California to an elevation of about
7000 feet. It was used by Native Americans in basket weaving, thatching, fishing
poles and firewood. It is an important wildlife plant for birds, bees and butterflies
- where some of the latter are Lorquin's Admiral, Mourning Cloaks and Sylvan Hairstreaks. The
scientific name, Salix lasiolepis, is derived from the Latin Salix meaning
"to spring" because of fast growth, and the Latin word, lasiolepis meaning
"shaggy scales" of the flowering parts. All of the photos were
taken on or near More Mesa.
