Heart-leaved golden alexanders are North American natives.
Identification: Plants reach 12-30" (30-76 cm) in height. Lower leaves are divided into threes; upper leaves in two. Leaves are up to 4" (10 cm) long and 3" (7.6 cm) wide, heart-shaped, with finely toothed edges. Flowerheads have the overall shape of a gently curved umbrella about 2-3" (5-7.6 cm) across, divided into smaller groups (parasols?). The smaller groups approximately 25 tiny yellow flowers, each less than ⅛" (3.2 mm) across, each with five petals. The dried seedheads become purple.
