Very popular ground cover. It spreads quickly by runners, making a mat of dark green leaves that grow 2 to 3 inches wide in full sun and 4 to 5 inches wide in part shade. Selections with bronze- or metallic-tinted leaves keep color best in full sun. The flowers, usually blue, are borne on 4 to 5 inch high spikes. The plant flowers in early May to mid-June. If established plants are set apart in the spring, they will cover the soil in one growing season. Do not set the plants too deep. The crown should never be covered. In the spring or early fall, rooted "runner plants" can be dug from established plantings and replanted elsewhere.
It is reportedly only slightly less aggressive than regular green vinca, so it should be kept in mind that once established it is pretty darned hard to ever be rid of it, since it grows back from any missed bit of root. So select its location with permanency in mind. It can be particularly useful in container gardening.
It does not require much moisture, but when getting established a regular watering schedule & a slow-release fertilizer can give it a leafy boost.
