One way of figuring out when to plant achimenes is to refer to the USDA zone info for Latrobe.

Planting Calendar for Achimenes

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

Since achimenes are not cold tolerant you need to wait until after all chance of frost has passed before you can plant them.

The earliest that you can plant achimenes in Latrobe 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 achimenes and expect a good harvest is probably August. You probably don't want to wait any later than that or else your achimenes may not have a chance to really do well. Starting your achimenes indoors is a great way to get them started a little bit earlier.
