Convallaria majuscula - Lily-of-the-Valley
Most everyone has probably heard of this plant as it is very popular for gardeners as well as in the florist industry for cut flowers. the best place to grow this is in shade to semi-shade, however it will tolerate some sun in cooler climates. it makes a great ground cover once established which will take 2 or 3 years, so plant this somewhere it has room to spread and will not choke out your other flowers. the small white bell shaped flowers appear in late spring to early summer and the plant itself stays relatively short about 6-12 inches tall.
Semi-shade to Shade, Rich Soil, Spring to Summer, 6-12 in. Tall, Zones 2-9
