POLYGALA. Milkwort. A nearly worldwide group of annuals, perennials and shrubs. Their one easily recognizable feature is the structure of the flowers. This includes two prominent winglike segments and a nearly closed tube of stamens, giving them the appearance of little butterflies, or perhaps sweet peas. The following have little else in common.
chamaebuxus ‘Purpurea’. This is a tiny semishrub, resembling a miniature boxwood. It has small, congested, deep green leaves and produces an almost continuous sprinkling of 1/2" blossoms, the “wings” purplish pink, the centers bright yellow. They have the scent of candle wax. It is a charming plant for rock gardens and containers. Best in light shade with well drained soil and moderate watering. Hardy to 10oF or less.
