Planting & Growing
Wooly Blue Violet will grow to be only 4 inches tall at maturity extending to 6 inches tall with the flowers, with a spread of 6 inches. When grown in masses or used as a bedding plant, individual plants should be spaced approximately 5 inches apart. Its foliage tends to remain low and dense right to the ground. It grows at a fast rate, and under ideal conditions can be expected to live for approximately 3 years. As an herbaceous perennial, this plant will usually die back to the crown each winter, and will regrow from the base each spring. Be careful not to disturb the crown in late winter when it may not be readily seen!
This plant does best in full sun to partial shade. It prefers to grow in average to moist conditions, and shouldn't be allowed to dry out. It is not particular as to soil type or pH. It is somewhat tolerant of urban pollution. Consider covering it with a thick layer of mulch in winter to protect it in exposed locations or colder microclimates. This species is native to parts of North America.
