White pansies arrive in fall and run straight through to frost, giving you reliable color when most annuals have checked out for the season. Cool Wave's trailing habit means they spill nicely from baskets and window boxes without needing much fussing once they're settled in.

Plant them in organically rich soil where they get at least a few hours of sun—they're not picky about location otherwise. Deadheading keeps flowers coming, but they'll produce steadily even if you don't stay on top of it.
