Since 1894, nineteen occurrences of pink corydalis (Corydalis sempervirens) have been documented in northwest Montana. Nine of these sightings occurred in Glacier National Park, which is at the southern edge of the range for this plant. Pink corydalis grows best in open areas that provide full sunlight and is commonly associated with disturbed or rocky, exposed sites. Germination appears to be boosted by heat as it is found most abundantly in recently burned forests. As a fire-dependent species, the main threat to pink corydalis may be from fire suppression activities. The multi-divided, bluish-green leaves add to the delicate, lacy appearance of the plant. The pink corydalis flowers in July and produces pinkish, yellow tipped flowers.
