One of the first steps you take when you are making a decision about your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

One way of determining when it's possible to plant nemesia is to consult the USDA zone info for Blackfoot.

Planting Calendar for Nemesia

Frost tolerance for nemesia:	Not tolerant of frost.
When to plant:	After all chance of frost has passed.

It's probably a bad idea to plant nemesia until after the last frost because they require warm weather.

The earliest that you can plant nemesia in Blackfoot is April. However, you really should wait until May if you don't want to take any chances.

The last month that you can plant nemesia and expect a good harvest is probably August. If you wait any later than that and your nemesia may not have a chance to fully mature. Starting your nemesia indoors is a great way to get them started a couple of weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Blackfoot. It might get as low as -15°F during the coldest months of winter.

Since the USDA zone info for Blackfoot is just an average the actual date of last frost is different every year. Half of the time in Blackfoot there is a last frost after April 15 so just be sure to be ready to protect your nemesia if you have a late frost.
