The USDA Zone info is a great tool for gardeners to help us determine your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Highland you can determine when it's the best time to plant arctotis by looking at the USDA zone info.

Planting Calendar for Arctotis

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

Since arctotis are moderately cold tolerant you can plant them a little earlier in the year than other frost tender plants.

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

The last month that you can plant arctotis and expect a good harvest is probably October. Any later than that and your arctotis may not have a chance to grow to maturity. Starting your arctotis indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

In Highland the average date of last frost happens on February 15. In the coldest months of winter you can expect an average low temperature of 25°F.

Since the USDA zone info for Highland is not always accurate the actual date of last frost can change quite a bit from year to year. Half of the time in Highland there is a last frost after February 15 so be sure to be ready to cover your arctotis if you have one of those late frosts.
