Houttuynia cordata is distinguished for its ability to invade the entire farmland and spread closely all over the ground. When this plant eventually invades a farmland, it usually proves difficult to destroy except when tackled with tough elimination methods. The plant is capable of growing approximately up to 80cm tall with the distal part protruding vertically. Houttuynia cordata is characterised by greenish-yellowish color leaves that often grows up to 10 cm long * 6 cm wide in shady places and moist areas. The leaves are alternated with heart-shaped appearance while the stem usually produces adventitious roots. The plant bears horizontal rhizomes, which connect the erect aerial stems with each other.
