Ajuga reptans (Bugleweed)
Ajuga reptans, or Bugleweed, a slow-growing perennial ground cover and member of the mint family, is one of the darkest Ajuga's I have ever seen. Unlike its wayward mint relatives, it can be kept in check, but it would probably also look very nice in a large container or trough garden. The scalloped, deep green leaves are tinged with bronze and purple and are attractive in their own right, but in spring, there is another matter to consider: 10-inch spikes of shimmering blue/violet flowers that take it over the top. Ajuga reptans (Bugleweed) appreciates partial sun/full shade and moist, well-drained soil, but it is also adaptable to harsh conditions. Zones 4-9.
