Asarum caudatum (British Columbia wild ginger, western wild ginger, or long-tailed wild ginger) is native to rich moist forests of western North America from British Columbia to California and as far east as western Montana. It is an evergreen with flowers that develop from March to August.
Occasional watering during dry periods will keep the foliage looking fresh. Well established plants are completely drought tolerant but may have limp leaves that will perk up with autumn rain.
Young plants need extra phosphorus to encourage good root development. Look for a fertilizer that has phosphorus, P, in it(the second number on the bag.) Apply recommended amount for plant per label directions in the soil at time of planting or at least during the first growing season.
A prudent recommendation would be to provide 6-12 weeks at an average daily temperature of 40°F (5°C).
