Aruncus dioicus
(Walt.) Fern. var. acuminatus (Rydb.) Rydb. ex Hara
Goatsbeard/Bride's
feathers
There are 5 varieties, 4
native and 1 introduced. Variety acuminatus is the one in the Pacific
Northwest.
The
west coast variety acuminatus occurs from Alaska southward to northern
California. From the Cascades to the coast in Washington and much of Oregon,
but east in B.C. to the Selkirk Mountains.
Climate,
Elevation (for all varieties)
Submontane
to subalpine - Pacific, Cordilleran less frequently, and Atlantic North America.
Local
occurrence (where, how common)
Edge
habitats - edges of roadsides, forests, and streams at low to middle
elevations. Common north to the B.C. coast, rare north of there.
Moist
shady woods, especially along streams.
Plant
strategy type/successional stage (stress tolerator, competitor,
weedy/colonizer,
seral, late successional)
Commonly
inhabits exposed mineral soil on water-receiving flooded sites. In early seral
herbaceous communities near waterways or run-off channels on steep, often
shallow and rocky colluvial slopes.
Associated
species
No
information
May
be collected as: (seed, layered, divisions, etc.)
Seeds,
salvage, or divide rhizomes.
Seeds:
This
is a dioecious plant, so seeds must be collected from female plants. (Male
flowers are much "fluffier".) Professional opinions vary as to when
to collect seed - anywhere from July through November. Collect by gently
bending flower stalk and shaking seeds into bucket or strip seedheads with
fingers into bucket or bag and spread the heads on a newspaper to dry.
Salvage/Rhizome
division:
Salvage seedlings from development sites when
plants are young, in early spring, or rhizomes can be divided at this time.
Seed
germination (needs dormancy breaking?)
No
information indicates that it needs dormancy breaking. Some sources indicate
that seeds germinate easily.
Seed
life (can be stored, short shelf-life, long shelf-life)
No
information
No
information
Propagation
recommendations (plant seeds, vegetative parts, cuttings, etc.)
Seeds
germinate easily. Sow outdoors in fall in damp soil, or hydroseed. Or can grow
plants from seed in nursery first, which will form strong roots after one year.
Soil
or medium requirements (inoculum necessary?)
Prefers
moist, nitrogen-rich soils
Installation
form (form, potential for successful outcomes, cost)
Easy
to grow from seed or collected seedlings.
4-6
feet apart (garden)
Care
requirements after installed (water weekly, water once, never water,
etc.)
Prefers
moist soils, woodland setting, or some shade.
Female
plants will apparently readily reseed themselves and spread fairly rapidly. No
information on lifespan.

Note - This plant was very difficult to find propagation information on. Many
sources were checked but few contained this species in any detail. Most of the
information here is from the Native Plant Notebook and the USDA website- which
was very scant.)
