Bog Rosemary

Andromeda polifolia (an-DROM-eh-dah pol-ih-FOH-lee-ah)

Family: Ericaceae Native Shrub

Bog Rosemary, is a low, evergreen shrub or ground cover in the Ericaceae (blueberry) family. Growing from 8 inches to 3 feet in height and, in its native state, typically found in bogs. The shrub does not have many branches, but many shrubs will grow together to form a clump. The plant prefers a well-drained, moisture-retentive, lime-free, humus-rich soil and shade.Wet soils are tolerated well. It does not do well in heat and humidity and locations south of Zone 6. Plants spread slowly by means of suckers to become a very ornamental plant. The small, firm, narrow leaves are blue-green. Leaf margins roll under. Several small, bell-shaped, pink or white flowers occur together in a curved umbel at the tip of a branch. Bog Rosemary is one of several heath shrubs similar to Sheep Laurel, Bog Laurel, and Labrador Tea. Plant in a border front, or along a stream or pond margins, or in a rain garden. Insects, Diseases, and Other Plant Problems: No known diseases or insect pests. Does require acidic soil.
