Viola adunca, early blue violet, is an easy to grow woodland species that spreads by rhizomes and also self sows. It is most suitable for a larger scale garden where its cheerful spreading will not crowd delicate, small scale plants. The foliage is bright green and it produces many dark purple blue flowers to 4″ high from mid-spring to summer. It is quite adaptable and will grow in sun to part shade and in moist to dry soils. It is a widespread native wildflower found in all Western and far Northern US states and throughout Canada. It is hardy to -25 degrees F or lower.
