The USDA Zone info is a great tool for gardeners to help us estimate your gardening schedule. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

In Cotati you can figure out when it's possible to plant bellis by using the USDA zone info.

Planting Calendar for Bellis

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

Since bellis are moderately cold tolerant you can plant them a little bit earlier in the year than other frost tender plants.

The earliest that you can plant bellis in Cotati 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 bellis and expect a good harvest is probably October. You probably don't want to wait any later than that or else your bellis may not have a chance to fully mature. If you are starting your bellis indoors then you might be able to get away with starting them a few weeks earlier.
