I am planning on planting Peruvian Lily, or Lily of the Incas in my backyard.
Would they survive our winter?
I read somewhere that Peruvian Lily, or Lily of the Incas will only survive in Plant Hardness Zone 7 and above.
Also could you please tell me what is Toronto Plant Hardness zone 6 or 7?
Thank you for your question.
Toronto’s plant hardiness zone is 6a. Within any zone there will be variations, micro-climates, as some spots are more sheltered than others from the elements. There are some differing opinions about the plant hardiness for Peruvian lilies (Alstroemeria ) in zone 6 and some sites say zone 7 or 8.
Some sources suggest that Alstroemeria tubers will survive a winter in zone 6 if the plant is heavily mulched. Other sources suggest that it is best to dig up the tubers after the first light frost and store them in a plastic bag containing dry peat moss. Then to place the bag in a dark, cool (32-40°F) location.
Good luck with this pretty plant.
