HARDINESS ZONE

Our Guarantee will apply only if you order perennial plants or bulbs with a hardiness zone that is equal or inferior to yours.

For example:
- If you live in zone 3,
- Order plants and bulbs with a hardiness zone of 1, 2 or 3.

So, before making your selection, be sure that the plants and bulbs that you are ordering can withstand the variations of climate and temperature of your region, i.e. they will perform well in your hardiness zone, as indicated by your average annual minimum temperature (see chart below).

Of course, none of this applies to annuals which, by nature, are not hardy.

How to find my hardiness zone
• Click here: My Hardiness Zone
• Enter your postal code and click on Search. Your zone will appear.
