Viola praemorsa ssp. praemorsa

Canary violet or upland Violet has many subspecies in the PNW and west in general. This is our own Willamette Valley form of this intriguing handsome perennial. Large spoon shaped leaves have an underside with conspicuous hairs. The top of the leaf is glossier. In April-May bright yellow flowers appear. The bottom petal has conspicuous black whiskers. In our region this violet is local in the most undisturbed sites but it shows very good persistence in competition with non-native introduced grasses. My experience is that it favors rocky and scree sites that remain somewhat cool- for instance the north side of a steep slope. To 6″ tall and forming expanding plants. Winter deciduous. Arrives early in spring and can go summer dormant with high heat. Excellent planted in fall or winter and left to its own devices. Average to enriched soil yields the best results. This is one of the showiest violets native to the Willamette Valley. Fairly long lived. Little deer resistance. Some associated plants are Olysinium douglasii, Sedum spathulifolium, Dodecatheon hendersonii. Oregon native plant.
