Annual Plants for Full Sun
These plants can be grown from seed and will die within a year. However, many will have produced seeds for you to collect and the seeds you miss will drop to the ground and may have a good chance of germinating when the time is right. Consider an irrigation set up as annuals have shallow roots so can only access the water in the soil close to the surface.
