Before planting it is a good idea to find your USDA Zone info to determine your garden schedule. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

The USDA zone info for Brazil can be looked at to estimate when it's possible to plant cuphea.

Planting Calendar for Cuphea

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

Since cuphea require warm weather it's important to wait until after the last frost has passed before you can plant them.

The earliest that you can plant cuphea in Brazil 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 cuphea and expect a good harvest is probably August. If you wait any later than that and your cuphea may not have a chance to fully mature. Starting your cuphea indoors is a great way to get them started a few weeks earlier.

Last Frost Date

The average date of last frost is April 15 in Brazil. In the coldest months of winter you should expect an average low temperature of -15°F.

Always keep in mind that the actual date of last frost is just an average because it is based on the USDA zone info for Brazil and it can change quite a bit from year to year. Half of the time in Brazil it frosts late in the year after April 15 so make sure that you are prepared to cover your cuphea if you have a surprise late frost.
