Ø
Ø Moist,
low elevation (4), or can be found in higher elevation forested wetlands (1)
Local occurrence (where,
how common)
Ø Wet
prairies and meadows, sloughs, marshes, lake shores, forested wetlands (1,4);
forms dense stands in standing water (1), most common of the evergreen sedges
in local valleys and floodplains (4)
Ø See
previous
Plant strategy type/successional stage (stress-tolerator, competitor, weedy/colonizer, seral, late successional)
Ø Able
to tolerate fluctuating water levels and brackish conditions
Ø
May be
collected as: (seed, layered, divisions, etc.)
Ø Rhizome/culm plugs
Ø
Seed
Collection restrictions or
guidelines
Ø Collect
seeds in late summer to early fall
Ø
Collect culms in fall (best to use young
plants)
Seed germination (needs dormancy breaking?)
Ø Soak
seeds in water for 24 hours (5)
Propagation recommendations (plant seeds, vegetative parts, cuttings, etc.)
Ø Sow
seeds on surface of growing medium in flats in spring (5)
Ø Seeds
germinate 30 days after sowing (5)
Ø Transplant
germinated seedlings to individual containers (2x7 in. tubes) for outplanting (5)
Ø
Harvested culms can be planted into
larger containers for later division
Soil or
medium requirements (inoculum necessary?)
Ø Growth
medium for germination flats should be peat, perlite,
major and minor nutrients, gypsum, and dolomitic lime
mix (5)
Ø
Growth medium for transplants should be a
standard potting mix consisting of peat, fir bark, perlite,
and sand (5)
Installation
form (form, potential for successful outcomes, cost)
Ø Container
plug with established seedling (usually after two months)
Ø
Harvested culms
Ø
Seeds can also be scattered on site in
the fall, but they may be washed away by fluctuating water levels (2)
Ø Either
one container plug or three culms on 20” centers
Care requirements after installed (water weekly, water once etc.)
Ø Soil
must be kept moist (5)
