Chinese Violet, known in Thai as oum saeb and bah yah, is a fast-growing, perennial creeper in the family Acanthaceae, and with the botanical name Asystasia gangetica subspecies micrantha.

The plant has bright green somewhat heart-shaped leaves and long stalks that have small white flowers with purple blotches on the lower lip.

It is an invasive weed that quickly forms dense mats and out-competes native vegetation, thus reducing habitat and food for native fauna.
