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

One way of estimating when you can plant nolana is to use the USDA zone info for Zone 3a.

Planting Calendar for Nolana

Frost tolerance for nolana:	Not tolerant of frost.
When to plant:	After the last frost when the weather gets warmer.

Nolana require warm weather which tells us that you must wait until it warms up after all chance of frost has passed before you can plant them.

The earliest that you can plant nolana in Zone 3a is May. However, you really should wait until June if you don't want to take any chances.

The last month that you can plant nolana and expect a good harvest is probably August. You probably don't want to wait any later than that or else your nolana may not have a chance to really do well. Starting your nolana indoors is a great way to get them started a few weeks earlier.

Last Frost Date

On average the last frost has passed is on May 15 in Zone 3a. In the coldest months of winter you can expect an average low temperature of -40°F.

It's important to remember that the actual date of last frost is not always accurate because it is based on the USDA zone info for Zone 3a and it is different every year. Half of the time in Zone 3a you get surprised by a frost after May 15 so always be ready to cover your nolana in the event of a surprise late frost.
