The flowers are large, showy, bright orange, with deep red or purple spots near the center, the petals curl backwards. The flowers are few to many at the top of the stem. The seed pods are elongated, tapering near the base (Douglas et al., 1991). Photo by Moralea Milne.

OTHER NAMES
Columbia lily, panther lily

FAMILY
Liliaceae

ECOLOGICAL ATTITUDE
Western North American species found in moist, open forests and grasslands from sea level to subalpine elevations. Found in British Columbia throughout the province south of the 54th parallel. Occurs in early seral communities on hydrophobic, often colluvial, soils. (Klinka et al., 1995).

GROUND TEXTURE
Very well drained sandy soils rich in organic matter (Pettinger and Costanzo, 2002).

NUTRIENT
Nitrogenous soils (Klinka et al., 1995).

SOIL REACTION SALINITY
Prefers acidic loam.

HUMIDITY REGULATION
Well-drained, moderately dry to fresh soil (Klinka et al., 1995).

SHADOW TOLERANCE
Prefers a partially shaded spot with shrub or perennial cover that keeps the soil cool and moist but allows the lily stalk to enjoy sunlight.

SUCCESSION STATUS
Characteristic of young seral forests with an open canopy (Klinka et al., 1995).

SITE RENOVATION
Not practical as a type of rehabilitation.

WILDLIFE
Generally not eaten by wildlife.

LANDSCAPING
Gives a nice show in a perennial border as a background for lower growing plants (Pettinger and Costanzo, 1996).

FIRST NATION
Interior First People typically ate tiger lily bulbs after they had been boiled or steamed for several hours (Douglas, Meidinger, Pojar, 1991).

FLOWERING TIME
June to July

FRUIT MATURATION
late autumn

SEED COLLECTION TIME
Late autumn to early winter.

COLLECTION AND ABSTRACTION
Seeds can be collected in late autumn after the plant has died. The tapered oblong seeds can be found around the base of the plant.

SEED STORAGE
Not recommended.

TREATMENT OF FRUIT SEED REST
Sow the seeds in the fall to allow the dormant period to break naturally. This may not be the case for two years as the seeds require multiple warm-cold-warm cycles to trigger germination.

Vegetative propagation
Successful propagation can be achieved by onion division. Divide the bulbs in the fall after the plant has gone dormant. Flower bulbs should only be taken from the wild in salvage situations. Otherwise, get plants or flower bulbs from a specialist nursery. Garden onions can be divided in autumn or onion scales can be used for propagation. Plant the bulbs 5-7.5 cm deep in autumn or spring
