Taxonomic Notes

Although the flowers are exceptionally showy, the plant itself is generally very tiny and can easily be overlooked. The large flowers, tiny plants, coarsely-toothed succulent leaves, globose capsules, and occurrence on acidic (granitic) rather than basic substrates render this among the most distinctive of the province’s Primula species. It is also the only Primula species that occurs in coastal B.C.
