Before planting it is a good idea to find your USDA Zone info to estimate 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.

One way of getting a good idea when it's a good idea to plant lobelia is to refer to the USDA zone info for Hollister.

The last month that you can plant lobelia and expect a good harvest is probably October. You probably don't want to wait any later than that or else your lobelia may not have a chance to really do well. You can get started a little bit earlier by starting your lobelia indoors.
