Ajuga or bugle are native, spreading perennials with attractive green and purple leaves and predominately blue flowers. Flowers form short spikes and are usually tubular in shape which certain butterflies seek out. Ajuga form a dense mat of greenery up to 50 cm high making a lovely ground cover. They are suited to partial shade and well-drained soil so they are ideal for a cottage garden or flower bed. Ajuga are very simple to grow as they will tolerate acid, alkaline or neutral soil and do not require pruning.
