Product Information
Hardiness zone
-Will the plant you buy this season come back next year? It all depends on where you live.
To survive for several years, a plant must tolerate the lowest winter temperatures in the region where it is planted.
It is therefore important to identify the hardiness zone of your region.
An example ! You are in Montreal, in zone 5 (according to the charter of Natural Resources Canada)
• any plant in zones 5, 4, 3, 2 or 1 will return year after year to your area, it is said to be hardy.
• a plant in zone 6, 7, 8, 9 or 10 will be considered an annual and must be replanted each year.
