Milkweed is essential to your garden for helping increase monarch populations, since the butterfly can’t complete its life cycle without it. Add nectar-producing plants and you’ll have a true monarch oasis.
Our horticulturists’ suggestions:
|1||•||Common milkweed||Asclepias syriaca||Native perennial in Québec
Monarch host plant
If you garden in pots, choose bloodflower (Asclepias curassavica), a tropical milkweed, instead. Treat this species the way you would an annual, or grow it as an indoor winter plant, after cutting it back.

|4||•||Meadow blazing-star||Liatris ligulistylis||Perennial, native in the Canadian Prairies|
|5||•||Butterfly bush||Buddleja davidii||Shrub, not very hardy in the Montréal region|
