Species (common name, Latin
name)
White
Avalanche Lily/White Glacier Lily ,Erythronium montanum
From
southern
Climate, elevation
The
climate type for this species is alpine tundra & boreal. It is usually
found between 1100 and 1200 ft.
Local occurrence (where, how
common)
Habitat preferences
Moist
meadows and open forests in the montane and subalpine zones
Plant strategy type/successional stage (stress-tolerator,
competitor, weedy/colonizer, seral, late successional)
May be collected as: (seed,
layered, divisions, etc.)
Seed,
Bulb, Cutting,
Seed germination (needs
dormancy breaking?)
Stored
seed requires a period of cold stratification. Fresh seed can be planted and
will successfully germinate.
Seed life (can be stored,
short shelf-life, long shelf-life)
Can be stored as a bulb or seed. Can be stored for several
years in a cool dark environment.
Recommended seed storage
conditions
Refrigerated
and kept in dark dry area.
Propagation recommendations
(plant seeds, vegetative parts, cuttings, etc.)
The
seed can be sown as soon as it is ripe in a shady position in a cold frame. Water
lightly in summer, it should germinate in autumn or winter. Sow as early in
spring as possible in a cold frame. Sow the seed thinly so that it will not be
necessary to prick them out for their first year of growth. Give an occasional
liquid feed to the seedlings to make sure that they do not become nutrient
deficient. When the plants are dormant, pot up the small
bulbs putting 2 - 3 bulbs in each pot. Grow them in a shady position in
the greenhouse for another 2 - 3 years and then plant them out into their permanent
positions when they are dormant in late summer. Not much literature is
available about vegetative propagation of this species.
Soil or medium requirements
(inoculum necessary?)
Prefers
slightly acid soil conditions but succeeds in chalky soils if these contain
plenty of humus. Requires semi-shade, preferably provided by
trees or shrubs, and a well-drained soil. Succeeds in almost
any light soil, preferring one that is rich in humus.
Installation form (form,
potential for successful outcomes, cost)
Seeds
and bulbs are both a reliable source for propagating lillies and require little cost.
Recommended planting density
In
a 14” x 9” tray anywhere from 200 to 1000 seeds can be sprinkled on top of the
medium. 2-3 bulbs can be placed in a bucket to let germinate.
Care requirements after
installed (water weekly, water once etc.)
The
medium should be kept moist but should be a light well draining mix so as not
to over saturate the maturing plant.
Normal rate of growth or
spread; lifespan
Lilies
are perennial and an individual plant can survive for several years
