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.

A common way of determining when you can plant achimenes is to examine the USDA zone info for Torrance.

Planting Calendar for Achimenes

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

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

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

The last month that you can plant achimenes and expect a good harvest is probably September. You probably don't want to wait any later than that or else your achimenes may not have a chance to fully mature. If you are starting your achimenes indoors then you might be able to get away with starting them a couple of weeks earlier.
