Dodecatheon pulchellum (Raf.) Merr. var. alaskanum (Hultén) Reveal can be propagated either by seeds or division of roots.
Propagation by Seeds
The seeds of Dodecatheon pulchellum (Raf.) Merr. var. alaskanum (Hultén) Reveal can be sown outdoors in the early spring when the soil temperature reaches 50°F. The seeds should be sown on the surface of the soil and covered with a thin layer of soil. The soil should be kept moist until germination, which can take up to 3-6 weeks. Once the seedlings have developed their first set of true leaves, they can be transplanted into individual pots.
Alternatively, seeds can be sown in pots in a cold frame during the fall. The pots should be covered with a layer of mulch to protect the seeds from frost. In the spring, when the soil temperature reaches 50°F, the pots can be removed from the cold frame and the seedlings can be transplanted into individual pots or directly into the garden.
Propagation by Division
