This short-lived perennial is a native of moist to seasonable wet meadows and open woods from the Canadian border to Florida, west to Nevada. Its bright yellow flowers are borne in flat clusters on sparingly branched plants that brighten late spring gardens while its attractive heart-shaped basal leaves are attractive all season long and turn wine-colored in fall. Black swallowtail larvae are particularly fond of the foliage. Heart-leaf Alexander is very easy to grow, adapting to a wide range of soil and light conditions.
