Ajuga

Ajuga is one of the most indispensable groundcovers around. It has many uses and looks great much of the year.

Also known as carpetweed or bugleweed, ajuga forms a 6-inch-tall mat of glossy leaves that always seem to look neat and fresh. In many cases, the leaves are colored with shades of purple, white, silver, cream, or pink. Individual plants grow as a rosette, but they intertwine to form a solid carpet that withstands some foot traffic. Blue, lavender, pink, or white flower spikes adorn plants spring to early summer.

Ajuga is great in rock gardens, in the front of beds and borders, under leggy shrubs or small trees, along paths, and just about any other place in the landscape you want to cover the ground with attractive foliage and little flowers.
