You can figure out when it's possible to plant galium in Houston by reviewing the USDA zone info.

Planting Calendar for Galium

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

Galium tend to make it in mild cold which means that 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 galium in Houston 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 galium and expect a good harvest is probably October. You probably don't want to wait any later than that or else your galium may not have a chance to really do well. If you are starting your galium indoors then you might be able to get away with starting them a few weeks earlier.

Last Frost Date

In Houston the average date of last frost happens on February 15. In the coldest months of winter you should expect an average low temperature of 20°F.

It's important to remember that the actual date of last frost is just an average because it is based on the USDA zone info for Houston and it can change quite a bit from year to year. Half of the time in Houston last frost occurs after February 15 so make sure that you are ready to cover your galium if you have a late frost.
