Dormants die back to the roots in winter, are hardy throughout the USA, and require no care outside of regular weeding, watering and fertilizing. Best bloom is in U.S.D.A. Zones 3-9, minimum temperature range of -40* to 30* F.
EVERGREEN & SEMI-EVERGREEN FOLIAGE
Evergreens and Semi-evergreens do best in U.S.D.A. Zones 6-9; leaves tend to grow whenever temperatures begin to warm during winter or early spring. In Zones 9 and 10, Evergreen varieties have nice foliage throughout winter. Elsewhere, Evergreens retain attractive leaves down to 20* F. At 0* F., top growth will brown and wither like Dormants, but roots and growth buds are undamaged. With reliable snow cover or winter mulching, Evergreens grow and bloom well year after year even in severe climates. Our garden is located farther north than the state of Maine, yet we grow more than 150 Evergreen cultivars subjected to fierce wind, wild freeze-thaw cycles, heavy rainfall, and absolutely no mulch or protective snow cover. We take pride in our plants; please call if you would like help in choosing varieties or the best delivery time.
