Planting and Care
Cardinal flower prefers part shade, but tolerates full sun where grown in cool summers. This plant needs consistent moisture, apply a layer of organic matter as a mulch to retain soil moisture. Self-sows readily, but because it is a somewhat short-lived perennial, this is an asset. In spring or fall divide basal rosettes that form around the base of the parent plant. Pinch back plants for sturdier stems and bushier growth. Cut plants back in spring.
