From
It is less common in its northern range. (3)
Climate,
elevation
Pacific
silverweed grows in wet temperate
climates
It
tolerates:
·
moderate
rainfall
·
common
at mid to low elevations (3)
Local
occurrence
It
can commonly be found in coastal wetland areas.
Occasionally
it can be found inland. (6)
Habitat
preferences
The
Pacific silverweed prefers sunny coastal dunes to marsh edges, sandy
bluffs, wetland meadows
and mudflats. (2,4)
Plant
strategy type/successional stage
Tolerates
shade and wetland conditions.
Pacific
silverweed is a good competitor, and has a tendency to become weedy. (3)
Associated
species
Juncus spp.
(rushes), Carex spp. (sedges), Scirpus spp. (bulrushes),
May be
collected as: (seed, layered, divisions, etc.)
The plant may be collected as seed or divisions.
Collection
restrictions or guidelines
Seed
germination
No
dormancy breaking is necessary.
Seed life
(can be stored, short shelf-life, long shelf-life)
May
be stored short term. Information on long term storage was not
found in the available literature.
Recommended
seed storage conditions
Store
cleaned in a dry location at room temperature. (5)
Propagation
recommendations
Conflicting recommendations exist for what time of year
seeds should be sown. One source
recommends sowing in mid-winter (7), while another suggests early spring or
autumn.
Seeds should be sown outdoors in a coldframe, covered
containers or an unheated greenhouse.
When large enough, transplant into individual pots and move
into a greenhouse for the winter. Plant in late winter or early spring, after
the risk of freezing temperatures is past. (6,7)
Divisions may be planted right away if they are large
enough. Smaller divisions should be
potted up and grown in light shade in a cold frame until they are established.
(6)
Soil or
medium requirements
Requires
moist well-drained soil.
Prefers
alkaline but tolerates a slightly acidic soil. (6)
Installation
form (form, potential for successful outcomes, cost)
Plants
must be installed when fairly developed.
Small plantlets and smaller divisions will likely fail.
Install
after the last frost. (6)
Recommended
planting density
Not
in literature.
Care
requirements after installed (water weekly, water once etc.)
Do
not allow soil to dry out.
Normal rate
of growth or spread; lifespan
Short
lifespan, rapid growth (may become invasive) (3,7)
