During the Spring Festival of Flowers in April, these Viola flowers made an attractive border display for the Daylily Garden. Low and compact, viola plants are perfect in edgings, rock gardens, window boxes, and other containers. They also blend well with spring bulbs. Violas do best in moderate temperatures and should receive full sun only where weather is cool; otherwise, partial shade. Soil must be rich, moist and well drained; a mulch during summer helps. Keep faded flowers picked.
