Houttuynia cordata, the sole species in the genus Houttuynia, is a flowering plant native to Japan, Korea, southern China and Southeast Asia, where it grows in moist, shady places.Houttuynia is a herbaceous perennial plant growing to between 20 and 80 cm. The proximal part of the stem is trailing and produces adventitious roots, while the distal part of the stem grows vertically. The leaves are alternate, broadly heart-shaped, 4-9 cm long and 3-8 cm broad. Flowers, growing usually in Summer, are greenish-yellow, borne on a terminal spike 2-3 cm long with 4-6 large white basal bracts.The plant grows well in moist to wet soil and even slightly submerged in water in partial or full sun. Plants can become invasive in gardens and difficult to eradicate. Propagation is via division.Houttuynia in temperate gardens is usually in one of its cultivated forms, including: Chameleon this variety is slightly less vigorous than the species and has leaves broadly edged in yellow and flecked with red; Flore Pleno has masses of white bracts and the vigour of the parent species.
