Species
(common name, Latin name)
MacKenzie's willow -
West from Washington to
Climate, elevation
Low to moderate elevations. (from
0 - 7000ft in
Local occurrence (where, how common)
Along stream in lowlands to
lower mountain valleys.
Habitat preferences
Rocky streams and river edges to moist alluvial
terraces. Fine textured soils with moderate to high amounts of water.
Plant strategy type/successional
stage (stress-tolerator, competitor,
weedy/colonizer, seral, late successional)
Early pioneer, often replaces coyote willow (Salix exigua).
Associated species
Widely scattered overstory
of black cottonwood (Populus trichocarpa),
or water birch (Betula occidentalis).
Coyote, Drummon and whiplash willows are also common
(S. exigua, drummondiana,
and lasiandra). Also redosier
dogwood (cornus stolonifera),

May be collected as:
(seed, layered, divisions, etc.)
May be propagated
as seeds or by cuttings.
Collection restrictions or guidelines
Seed should be collected as
soon as fruit ripens. Hardwood
cuttings can be propagated easily without the use of rooting hormone.
Seed germination (needs dormancy
breaking?)
Seeds do not exhibit any sort of dormancy. Should be planted immediately
for best germination rates, or refrigerated in a sealed container for up to a
month.
Propagation
recommendations (plant seeds, vegetative parts, cuttings, etc.)
Seeds should be used to grow container plants. Cuttings may be
planted directly at site or grown in greenhouse.
Soil or medium
requirements (inoculum necessary?)
The plant is adapted to a wide variety of soils from coarse textured
soils to silt loams.
Installation form (form, potential for
successful outcomes, cost)
Most successful when greenhouse grown (80% cutting success), especially
for seeds. Seeds should be immediately planted for highest germination rates.
Recommended planting density
Care requirements after installed (water
weekly, water once etc.)
Normal rate of growth or spread;
lifespan
Shrub grows from 6 to 30 feet tall. Relatively long
lived.
