Cultivation and Uses
USDA hardiness zones:
Yes when established.
Full sun to avoid fungal diseases. This plant may get leggy in part shade.
Water once established:
Once or twice a month. Moist soil shortens its lifespan. It should be
kept dry in winter.
Very well drained, dry, pH 6.1-7.8 (slightly acidic to slightly alkaline). It is sensitive to
salt and dies in saline soil.
Bare soil is best because it dries quickly. Gravel is a second choice. Avoid organic mulch
which keeps the soil moist and promotes disease.
First Year Care:
Water lightly every day to establish an extensive root system, but do not overwater.
Remove spent flowers to extend bloom. Cut nearly to the ground after the last frost to
spur new growth.
Seed, root division.
Ornamental, hummingbird garden, xeric garden. The leaves are used in teas, the flowers
are used in salads. For other culinary mint plants, see Low Water Culinary Herbs
