Elevation occurrence
includes a range of sea level – 8,000 feet above sea level. It cannot grow in the shade, needs full sun
and moist-wet soils.
Local occurrence (where, how common)
Woodland, canopy,
riverbanks, stream banks, freshwater swamps, moist alluvial bottomlands, and
roadside ditches.
Riparian zones with
wet soil and full sun. It likes heavy
soils like clay.
Plant strategy type/successional stage (stress-tolerator, competitor, weedy/colonizer, seral, late successional)
It is a pioneer or
early seral species that can be found on moist
alluvial soil. Flooding helps keep this
species established due to its flood resistance.
Populus balsamifera trichocarpa, Salix lutea, S. exugua, Cornus sericea, Salix boothii, S. drummondiana, Alnus incana ssp. tenuifolia, Alnus rubra, Populus trichocarpa.
May be collected as: (seed,
layered, divisions, etc.)
Seeds are very tiny,
most commonly collected as cuttings.
Cuttings are
generally collected the same day as installation due to fast sprouting of root
formations. Seeds can be collected before
the capsule breaks, so frequent observation is recommended, should be around
late summer, early fall.
Seed germination (needs
dormancy breaking?)
Germination is
quickly accomplished with a moist seedbed.
Germination will take place within 12-24 hours of reaching the moist
seedbed. Light increases germination
rates.
Seed life (can be stored,
short shelf-life, long shelf-life)
Very small seed
life, only 4-6 weeks when stored at room temperature.
Storage can be extended
to 1 month with storage in a sealed bag in the refrigerator.
Propagation recommendations
(plant seeds, vegetative parts, cuttings, etc.)
Vegetative cuttings
are the easiest. Taking a cutting of the
current year to fourth year growth is recommended. Take them in late winter, early spring
(November – February). Seeds can be sown
on a moist medium with adequate light very easily.
Soil or medium requirements (inoculum necessary?)
Seeds can be grown
on moist sand. If pre-rooting the
vegetative cuttings, a mixture of 1:2 peat moss and sand that has been wetted
is the best choice.
Installation form (form,
potential for successful outcomes, cost)
Due to high
sprouting of buds, vegetative cuttings are the easiest and best way for
success. The key is having a wet soil.
Plant approximately
1-2 feet apart.
Care requirements after
installed (water weekly, water once etc.)
Make sure the water
level is continuously wet. Vegetative
cuttings like wet soils, especially clay soils.
This species is a
fast growing tree (2-3m in one year), but a short-lived tree (~25 years).
