Even your herbs start looking dramatic. But not these 18. These are your sun-loving, heat-happy, “bring it on” champions. Geraniums keep blooming like nothing’s wrong. Portulaca practically begs for more sun. And ornamental peppers? They live for drama. These container pros don’t just survive—they put on a show when the temps climb. No fuss. No droop. Just bold color and serious stamina. So when your weather app goes red, don’t panic. Pick the plants that know how to handle the spotlight—and the sizzle.
