Before planting it is a good idea to find your USDA Zone info to estimate your garden schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

One way of figuring out when it's possible to plant iberis is to check out the USDA zone info for Vancouver.

Since iberis do well in moderate cold you can plant them just a bit earlier in the year than other frost tender plants.

The last month that you can plant iberis and expect a good harvest is probably September. If you wait any later than that and your iberis may not have a chance to grow to maturity. You can get started a couple of weeks earlier by starting your iberis indoors.
