A way of estimating when it's the best time to plant arctotis is to refer to the USDA zone info for Richland.

Planting Calendar for Arctotis

Frost tolerance for arctotis:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since arctotis do well in moderate cold you can plant them a little earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant arctotis in Richland is February. However, you really should wait until March if you don't want to take any chances.

The last month that you can plant arctotis and expect a good harvest is probably September. You probably don't want to wait any later than that or else your arctotis may not have a chance to fully mature. Starting your arctotis indoors is a great way to get them started a couple of weeks earlier.
