This is one of my most favorite plants of all time. It is a wonderfully thick, low ground cover. It looks like spinnach and has a very robust texture. When it flowers it is beautiful, and in the winter it will stay out. It turns a most beautiful purple and hunter green color. It spreads and is kind enough not to choke out anything. My experience is it grows in the worst soil and the best soil. It will tolerate drying out between watering, but when the sun gets in the 100s it needs to be watered every day for a sunny spot like almost everything else in my area-expecialy when not thick (new area).

Bold coloured cultivar of Bugle.

Has large, deep purple-bronze, shiny leaves and reddish stems. Bears two lipped, blue flowers borne in whorls.

Loves constantly moist but well drained, poorish soil in light to full shade. It will tolerate some sun but too much will burn the leaves.

Will get lost in deep shade as the leaves are so dark, an alternative would be to interplant some other leaf forms of Ajuga reptans for more interest. Best grown in light shade where the colour really shows up.
