About

Ajuga pyramidalis 'Metallica Crispa Purpurea' is a low-growing, evergreen perennial that gradually spreads to form a dense mat. Its foliage showcases a bronze-purple hue, which deepens to nearly black during the winter months. In spring and continuing into summer, it produces short spikes adorned with blue flowers. This plant is well-suited for use in containers, troughs, rock gardens, or locations that receive partial shade.
