One of the first steps you take when you are determining your gardening schedule is find your USDA Zone info. The most important data that the zone info tells us is average last frost and the lowest expected temperature for your area.

In Rayne you can figure out when to plant heuchera by referring to the USDA zone info.

Planting Calendar for Heuchera

Frost tolerance for heuchera:	Tolerant of some frost.
When to plant:	Up to 5 weeks before last frost.

Since heuchera are moderately cold tolerant you can plant them a bit earlier in the year than more sensitive plants.

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

The last month that you can plant heuchera and expect a good harvest is probably October. You probably don't want to wait any later than that or else your heuchera may not have a chance to really do well. If you are starting your heuchera indoors then you might be able to get away with starting them a little bit earlier.
