Range
Climate,
elevation
Found from 950 to 3050 m in elevation
Local
occurrence (where, how common)
Most common in the
Habitat
preferences
Open coniferous forests with dry, well-drained sandy loam to silty loam soils.
Plant
strategy type/successional stage (stress-tolerator, competitor,
weedy/colonizer, seral, late successional)
This plant is a stress tolerator.
Associated
species
Douglas-fir, Ponderosa pine, spruce, Lodgepole pine, Redwood, Western hardwoods, Chaparral, juniper
May
be collected as: (seed, layered, divisions, etc.)
Seeds on or off the plant. Divisions and cuttings (although not recommended)
Collection
restrictions or guidelines
It is best to collect during late fruit development by hand or by picking fruit off the ground.
Seed
germination (needs dormancy breaking?)
Seeds require hot water scarification followed by cold stratification at 4°C for 90 days in moist sand. Clean the fruit by macerating and separating the nutlets by floatation or blowing.
Seed
life (can be stored, short shelf-life, long shelf-life)
Recommended
seed storage conditions
Pre-soak dried seed in boiling water for 10 - 20 seconds or burn
some straw on top of them and then stratify at 2 - 5°c for 2 months.
Propagation
recommendations (plant seeds, vegetative parts, cuttings, etc.)
Seed - best sown in a greenhouse as soon as it is ripe. The seed
usually germinates in 2 - 3 months at 15°c. When large enough to handle, prick
the seedlings out into individual pots and grow them on in a cold frame or
greenhouse for at least their first winter. Plant out in late spring or early
summer.
Cuttings of side shoots of the current season's growth, 5 - 8cm
with a heel, August to December in a frame. The cuttings are very slow and can
take a year to root. This species is very dificult from cuttings.
Division in early spring. Take care because the plant resents root
disturbance. Pot the divisions up and keep them in a lightly shaded position in
a cold frame or greenhouse until they are growing away actively. Layering in
spring
Soil
or medium requirements (inoculum necessary?)
Greenleaf manzanita grows on dry, well-drained sandy loam to silty loam soils.
Installation
form (form, potential for successful outcomes, cost)
Seedlings grown in the greenhouse have the best chances for survival. Cuttings can be used but are very difficult to root as are divisions.
Care
requirements after installed (water weekly, water once etc.)
Water moderately for first year.
Normal
rate of growth or spread; lifespan
Up to 2 meters tall and 3 meters wide.
