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

A way of estimating when to plant nemesia is to refer to the USDA zone info for Richmond.

Planting Calendar for Nemesia

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

Since nemesia are not cold tolerant you really should wait until after the last frost has passed before you can plant them.

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

The last month that you can plant nemesia and expect a good harvest is probably September. If you wait any later than that and your nemesia may not have a chance to really do well. If you are starting your nemesia indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Richmond the average date of last frost happens on February 15. In the coldest months of winter you should expect an average low temperature of 20°F.

Always keep in mind that the actual date of last frost is an average because it is based on the USDA zone info for Richmond and it can change quite a bit from year to year. Half of the time in Richmond there is a last frost after February 15 so always be ready to protect your nemesia if you have one of those late frosts.
