One of the best tools that you have as gardeners to help us estimate your gardening schedule is the USDA zone info. The zone info helps tell us things like average date of last frost and lowest expected temperature for your area.

The USDA zone info for Zone 12a should be reffered to in order to estimate when you can plant hosta.

Planting Calendar for Hosta

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

Hosta do well in a little bit of cold which tells us that you can plant them a bit earlier in the year than plants that are more sensitive to the cold.

The earliest that you can plant hosta in Zone 12a 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 hosta and expect a good harvest is probably November. If you wait any later than that and your hosta may not have a chance to grow to maturity. You can get started a few weeks earlier by starting your hosta indoors.

Last Frost Date

In Zone 12a it never frosts. It might get as low as 50°F during the coldest months of winter.

Keep in mind that the actual date of last frost may not be accurate from year to year because it is based on the USDA zone info for Zone 12a and it is different every year. Since it never frosts in Zone 12a you do not have to be ready to protect your hosta in the event of one of those late frosts.
