Since sutera are one of those plants that can tolerate a tiny bit of cold weather you can plant them slightly earlier in the year than other frost tender plants.

The last month that you can plant sutera and expect a good harvest is probably August. You probably don't want to wait any later than that or else your sutera may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your sutera indoors.
