Candy corn is the cold-hardiest Cuphea in cultivation, and its timing is part of what makes it valuable: the bright yellow-and-orange tubular flowers peak in late summer through fall, precisely when much of the garden is winding down. The color combination is cheerful without apology, and the pollinators — butterflies especially — treat it as a vital late-season fuel stop. In zones 8 and warmer it can persist as a shrubby perennial, dying back in hard freezes and resprouting from the roots as temperatures rise in late March. In cooler climates it is grown as an annual, where it still gives a substantial show from planting through first frost.

Full sun is non-negotiable for maximum bloom. Young plants need consistent moisture to establish, but once settled in the ground Candy Corn becomes meaningfully drought tolerant. A cutback in late winter — before the new flush of growth begins — is the main task it asks of a gardener. It works well in pollinator gardens, cottage borders, or containers, and its compact, upright habit does not require staking or much intervention. Aphids are the one thing to watch for, and they are easily managed early.
