Wood-sorrel
Oxalis oregana
Temperate
climates at low to medium elevations (4).
Local occurrence (where, how common)
In
deep shade of mature alluvial forests.
Requiring moist conditions,
it forms understory groundcover in late successional conifer forests (1).
Divisions
in mid September (5).
Remove all but one or two
leaves from plant division. Each
division must contain a root or rhizome mass. (5).
Seed germination
Seeds require no seed
pretreatment. Other members of the Oxalis
genus are weedy pests in greenhouse environments (6). Seeds planted in cold frame in late winter to
early spring. Transplant seedlings into
individual pots when large enough to handle and plant in late spring or early
summer (3).
Short
shelf-life, best if sown as soon as ripe (3).
In restoration practices,
propagation of divisions from vicinity of site is recommended. Seeding is also an option, but no success
rates were found.
In field,
moist humus. In nursery environment, standard potting mix of peat moss, fir bark, perlite,
and sand (5).
Installation form
Transplanting divisions is
cheap and survival averages 90% (5).
Care requirements after
installed
Water transplanted divisions
in well. No additional watering
requirements specified (5).
Can be an aggressive
groundcover in appropriate growth conditions (3).
