Zone 9 Plants (9a And 9b)

About

Zone 9 is characterized by its longer growing season, mild winters, and warm summers. With a nine-month growing season, this is a great area to both live and start a garden! Houston, Corpus Christi, Jacksonville, Palm Springs, and Sacramento, are just a few cities that have this warm Zone 9 weather. Zone 9 is split into two subzones, Zone 9a and 9b. Zone 9a has a minimum average winter temperature of 20 degrees F to 25 degrees F. Zone 9b is a bit warmer, and has a minimum average winter temperature of 25 degrees F to 30 degrees F. The warmer winters in this zone mean you get a really lovely, long growing season! The summers do get a bit warm, so you do have to be careful when temperatures start peaking in those hotter months.
