The lifecycle of annuals is generally completed in one season. They develop from seed, flower, die, and then need to be planted again each season either by seed or transplant. While they may not last long, there is no easier way to color your world than adding annuals to your garden beds and containers. 

 

We are blessed living in San Antonio; due to our generally mild climate, many annuals extend through multiple seasons. At Rainbow Gardens, you can find annuals appropriate for each growing season. That means spring, summer, fall and winter you can surround yourself with beautiful blooms and cheerful color! Today I’m offering a few seasonal lists containing favorite annuals that do well in our San Antonio area. Take notice that many annuals that do great in spring could also have a spot in your gardens in fall due to the similarity of temperature and climate during those seasons in our city. Some annuals may bloom continuously or off and on through multiple seasons.

Planting the following favorite San Antonio annuals during the ranges specified below offers you your best chance at blooming success.
