Related to culinary ginger growing in tropical climates, Canadian wild ginger (Asarum canadense) is cold-hardy through USDA Hardiness Zone 3 without winter protection. It favors light to dense shade, ideal for a naturalized woodland region.
Ornamental ginger is a shade-loving perennial. It’s low-growing, with big, somewhat heart shaped, leathery, dull, hairy, grey-green leaves.
The flowers are tiny, cup shaped, and purplish to reddish brown in color. They possess the odd habit of blooming beneath the leaves at the base of the plant. You’ve got to really look to find them.
Canadian wild ginger is native to the northern areas the Great Plains of North America, in the acidic soil of woodlands.
Select a site. The soil in the planting site ought to be damp and rich, like the ground in shade gardens or woodlands.
Ready the planting site by excavating a hole about 12-inches in diameter. Combine the ground you removed with an equivalent quantity of garden compost. Add a number of the improved land back in the hole. Form the ground in the base of the the hole into a shape that is mounded.
Plant ornamental ginger by placing the roots in addition to the knoll of improved land in the planting hole. Fan out the roots so they’re not tangled and equally spaced. Back fill the hole with more improved land so the hole is slightly overfilled. Firm the soil gently but securely round the bottom of the plant.
Water in the recently transplanted Canadian wild ginger by means of a hand watering can. Use enough water to completely moisten the earth to the depth of the main ball. Then, supply the equivalent of 1-inch of rain each week to ginger plants. Wild ginger should be watered when rain is rare, for the best results, and isn’t tolerant of drought.
