Lake Mistassini Primrose
Primula mistassinica
Common Names: Mistassini Primrose, Lake Mistassini Primrose, Bird’s-eye Primrose
Description
An unusual and very tiny, delicate member of the Primrose family, Primula mistassinica is a northern native wildflower that brings understated elegance to cool, rocky, and moist habitats. In late spring, clusters of soft pink to lavender blooms rise on 10 cm (4 in) stems above neat rosettes of foliage. Its charm lies in both its rarity and its adaptability to small-scale plantings, making it a gem for specialized gardens.
The common name Lake Mistassini Primrose comes from Lake Mistassini in Quebec — the largest natural lake in the province — where this species occurs naturally along its rocky, windswept shores. Its presence there reflects the plant’s preference for cool, moist, and often calcareous environments.

Among the rare plants we grow—alongside Dwarf Lake Iris and Lakeside Daisy—all sourced from nursery-stable seed lines collected over 30 years ago, long before many wild populations became imperiled. These plants are the result of decades of careful stewardship, not wild digging.
