Bushy, 1-2 ft. tall plants covered in spikes of brilliant blue summer flowers. Leaves bright green, veined, lance-shaped. Tough enough to use as a ground cover in poor dry soils, beautiful enough to edge flower borders. Plant under crimson roses to make both colors pop. Prefers afternoon shade in hot climates. Milder scented than most Nepetas; less likely to attract cats. Winter hardy to zone 4. Grows nicely with Palace Purple Coral Bells.
Growing Blue Carpet Nepeta Seeds
Plant Nepeta Seeds: Sow seed in cell packs or flats, press into soil but do not cover. Light aids germination. Kept at 70° F., germination is in 14-45 days. Can direct sow (barely cover), in groups of 6-8 seeds spaced 12-18 in. apart. Thin to the strongest plant.
Grow Nepeta: Full or part sun, prefers afternoon shade in hot areas. Well-drained soil. Needs average to little water once established. Cut plants back by half after bloom, or cut flowering stems down to ground level. In spring, remove old growth to make room for new stems. Deer and rabbit resistant. Attract bees and butterflies.
