Clump perennial with ground covering growth and purple-blue flower from late spring. Canadian hybrid bred to withstand harsh conditions. One of several top performing catmints in Chicago Botanic Garden trials.
Grows very densely, about 1.5' tall x 2' wide. Gray aromatic leaves, flowers for very long period - in cooller areas blooms continuously throughout summer to fall, in hotter areas will stop blooming in early to mid summer, but can be easily cut back, because it re-sprouts very quickly and will set up another flush of blooms.
Full sun, half shade, soils with some drainage - average soil, shallow, rocky, sandy, gravelly soils. Medium moist to dry. Hardy in zones 3 to 9.
Excellent mound forming and dependable perennial for sunny borders, great edging plant of filling plant in public or private gardens. Combine with Echinacea, Monarda bradburyana, Monarda fistulosa, Rudbeckia, Paeonia, Penstemon digitalis, Salvia nemorosa, yucca, grasses and many other native or non-native perennials for drained or drier soils.
