Cuphea 'Firecracker' grows as a neat, upright annual that hits its stride in heat—the hotter it gets, the more tubular flowers appear in shades of red and yellow. Butterflies and hummingbirds find it irresistible, and it keeps flowering right through our warmest months without complaint.

Plant it in full sun with decent drainage, and water during dry spells. It'll stay compact and busy all season long, making it a solid choice for beds, borders, or containers where you want reliable color without fussing.
