Oenanthe javanica aka Java Waterdropwort

Taxonomy

Oenanthe javanica, commonly known as Java waterdropwort, water celery, water dropwort, Chinese celery, Indian pennywort, and Japanese (flat leaf) parsley, is a deciduous, moisture-loving, spreading perennial herb. It belongs to the Oenanthe genus and is native to East Asia, with a widespread distribution in temperate and tropical Asia. It is also found in Queensland, Australia. However, it should not be mistaken for plants like Cryptotaenia, also called "Japanese wild parsley," or Apium graveolens var. secalinum, known as "Chinese celery." This herb grows up to 1 meter in height and has fibrous roots emerging from all nodes. Its leaves are divided, toothed, and have a grey-green color with cream margins tinged with pink. In late summer, clusters of small, star-shaped white flowers adorn the plant. The leaves are aromatic, glabrous, and possess a sheath covering the stem, while the leaflets are crinkled and divided into lobes.
