How to Choose
When selecting annuals for the beach, prioritize salt tolerance, drought resistance, and adaptability to sandy, nutrient-poor soils.

Also, think about bloom time and color to ensure continuous interest throughout the growing season. Lastly, choose plants that attract pollinators or provide ecological benefits to your coastal environment.
