Lepechinia hastata, known as pakaha in its native Hawaii, resembles salvias in many respects, with its spikes of deep magenta flowers from August through October. A nonhardy perennial, this plant will still reach up to 4 feet in height with a flower spike of an additional foot. Its exotic-looking, large leaves are mint-scented and completely cover the soil, thus eliminating weeds. Plant Lepechinia hastata in full sun (or very limited shade) in moist, fertile soil. This plant is reputed to contain antibiotics and deters deer.
