Known for its rock hardiness, this aggressively spreading groundcover juniper is one of the most functional plants you'll ever use. Deep green summer foliage color turns nearly purple in the winter months, adding an unusual color to the winter landscape. A plant that's very tolerant of poor soil conditions, 'Bar Harbor' is best used in large group plantings. Plant in full to partial sun. Prune in early spring before new growth begins. Do not prune beyond where green growth is; avoid shearing.
