Scaevola spreads in a low mound and trails gracefully over pot edges, making it a natural choice for hanging baskets and window boxes through the warm season. The fan-shaped flowers keep coming without deadheading, and the plant handles heat and occasional dry spells better than most tender annuals.

Set it in full sun for the best flower show. Water when the soil surface dries, then let it go about its business—it's not demanding once established.
