Cyclospermum leptophyllum

Common Name(s):

Previously known as:

  • Apium leptophyllum
Description

Marsh parsley, in the Apiaceae (or carrot) family, is a summer annual. It has finely-dissected leaves and forms a branched mound up to 2 feet tall. Flowers are small, white, and tinged pink. Young seedlings strongly resemble wild carrot seedlings and emerge from mid-spring though mid-autumn with multiple generations per year. Plants prefer moist areas, growing well on irrigation ditches and in standing water of production areas. No data are available on herbicide effectiveness.

Marsh parsley is also known by the Latin name Apium leptophyllum.
