Before planting it is a good idea to find your USDA Zone info to determine 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 estimating when it's possible to plant rudbeckia is to use the USDA zone info for Mountain View.

Planting Calendar for Rudbeckia

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

Since rudbeckia are moderately cold tolerant you can plant them just a bit earlier in the year than other plants that might not handle the cold.

The earliest that you can plant rudbeckia in Mountain View 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 rudbeckia and expect a good harvest is probably October. Any later than that and your rudbeckia may not have a chance to really do well. You can get started a couple of weeks earlier by starting your rudbeckia indoors.

Last Frost Date
