Characteristics:
D. pauciflorum is an alternate name and may have priority.
D. pauciflorum in Davis 1953 and in Daubenmire 1970.
Reproduces sexually by seeds.
2n=44, 88 (Baldwin et al 2004).
Insect pollinated.
Flowers are perfect.
Fruit is a capsule.
Dodecatheon is a polyploid group and the species sometime grade into one another (Baldwin et al 2004).
There is conflicting information on edibility, some sources say it is poisonous, others that the roots and leaves are edible.
D. pauciflorum is a minor component of the diet of Rocky Mountain elk in spring (Kufeld 1973).

Other propagation information:
Can be propagated from seed but plants dug from the wild usually die (Parish et al 1996).
Reproduces sexually by seeds.



Notes: Dodecatheon pulchellum takes a while to grow and it needs space where it isn’t overtopped by other plants early in the season, but it is beautiful when in flower. Grows from seeds planted outside in fall. Container grown plants should be set out in the fall so they can begin growing while it is still too muddy to work in the garden in early spring. Blooms in May and goes dormant by mid June. Common names includes some variation of shooting star (Skinner et al 2005).
