Motherwort is an annual or biennial herb with dense fibrous roots on its main roots. Stems are erect, usually 30- 120 cm high, obtuse quadrangular, slightly grooved, with backward strigose, especially dense at nodes and edges, sometimes almost hairless at the base, multi-branched, or fertile small branches only above the middle of the stem.
The uppermost bract of inflorescence is subsessile, linear or linear-lanceolate, 3-65438 02 cm long and 2-8 mm wide, entire or with few teeth. Cymes are axillary, with 8- 15 flowers, spherical in outline, 2-2.5 cm in diameter, and most of them form long spikes far away.
Extended data:
Motherwort likes warm and humid climate and sunshine, and has low requirements for soil. General soil and barren hills and slopes can be planted, especially fertile soil, which requires sufficient water conditions, but it is not suitable for water accumulation and is afraid of waterlogging.
It grows in various environments, up to 3400 meters above sea level, including wild wasteland, roadsides, ridges, hillside grasslands and rivers, especially in sunny places.
Produced in all parts of China; Russia, Korea, Japan, tropical Asia, Africa and America are all distributed.
