How to identify this species of Dodecatheon: Distinguished from the other Shooting Star native to our province (Dodecatheon pulchellum) by:

1) Petals greater than or equal to 1.5 cm in length for D. conjugens vs. petals less than or equal to 1.5 cm for D. pulchellum (from Taxonomic Reminder for Recognizing Saskatchewan Plants).

2) Leaves hairy for D. conjugens, vs. leaves glabrous for D. pulchellum.

3) May bloom time for D. conjugens vs. June bloom time for D. pulchellum, but I've photographed both plants blooming in May.

When and where photographed: Photos taken May 8th, May 11th, and May 23rd, Cypress Hills, 400 km southwest of our home in Regina, SK.
