Plant Data Sheet
Species
Trillium ovatum
Range
Climate, elevation
Low to middle elevations (Pojar and Mackinnon, 1994)
Local occurrence (where, how
common)
Common in
Habitat preferences
Moist to wet woods, stream banks, shaded open areas.
Plant strategy type/successional stage (stress-tolerator,
competitor, weedy/colonizer, seral, late successional)
Summer drought tolerant.
Associated species
May be
collected as: (seed, layered, divisions, etc.)
Division. Seeds are covered with an
aril called an elaisome that attracts ants, which disseminate
the seed.
Collection restrictions or
guidelines
Flowers from April to June.
Seed germination (needs
dormancy breaking?)
Seeds have combinational dormancy where the radicle emerges after the first chilling stratification and the epicotyl emerges after a second chilling stratification. This requires two seasons for seedling emergence.
Seed life (can be stored,
short shelf-life, long shelf-life)
Seeds should be sown as soon as the seed ripens.
Recommended seed storage
conditions
Propagation recommendations
(plant seeds, vegetative parts, cuttings, etc.)
Rhizome division or seed. Seeds do best when planted outdoors soon after fruits have ripened. Seedlings take many years to bloom. Divide rhizomes in fall. (www.wildflower.org).
Soil or
medium requirements (inoculum necessary?)
Maintain even moisture levels until seedlings emerge.
Installation form (form,
potential for successful outcomes, cost)
Division
Recommended planting density
Spacing; 6-9 in. (15-22 cm)
Care requirements after
installed (water weekly, water once etc.)
Average Water Needs; Water regularly; do not overwater (plantsdatabase.com)
Normal rate of growth or
spread; lifespan
If planting seeds, leaves will not usually appear until the
second spring, and plants may take 5-7 years to reach flowering size.
