Additional Notes

Blue-eyed Marys as a group have extra-floral nectaries (packets of nectar) that occur outside the flower, sometimes on the leaves. Some populations of Collinsia parviflora in southern British Columbia are polymorphic for a gene that causes purple-spotted leaves. Read more here.

Ecological Indicator Information

A shade-intolerant, submontane to montane, North American forb distributed in Pacific, Cordilleran, and Central regions. Occurs on very dry to moderately dry, nitrogen-medium soils within boreal. temperate, cool semiarid, and mesothermal climates. Its occurrence increases with increasing temperature and decreases with increasing precipitation. Occasional in the open and in open-canopy forests on very shallow soils on rock outcrops and cliffs. Often inhabits meadow-like communities on water shedding-sites where early spring moisture is followed by mid-summer drought. Characteristic of moisture-deficient sites.
