A self-seeding perennial, L. cardiaca
is the most easily identified motherwort with leaves and flowers
alternating up its seed stalk giving this plant a strong geometric
expression. You might notice that there are several differently
shaped leaves at different stages of growth, a signature of motherworts.
Long blooming and slightly invasive, but easily controlled with
a hoe. Grow specs: 3-4 feet. Average garden soil. Full sun.
As the name implies, this plant has been used
to strengthen the heart. It also calms the nervous system and is
used in women's teas to promote menstruation, regulate menses and
aid in childbirth. (Photo © Steven
