Water Parsley is a flowering semi-aquatic perennial plant in the carrot family also known as Pacific Oenanthe. It is native to western North America from Alaska to California, where it grows in wet areas, such as streambanks. The plant is self-fertile. Requires a moist or wet fertile soil in a sunny position. It cannot grow in the shade. Celery-like odor.
Native Americans are reported to have used them medicinally. Whistles can be made from the hollow stems. Although no specific mention of toxicity has been seen for this species, it belongs to a genus that contains a number of very poisonous plants and so some caution is advised.
This perennial herb sports a characteristic carrot-family inflorescence, a flat-topped umbel made up of 5-20 tiny white flowers. These bloom from May to July. This species has soft, weak stems, which curl at the tips. If a stem touches the ground, it can send out runners from the nodes, having the potential to become invasive. Container planting is recommended.
Suitable for: light (sandy), medium (loamy) and heavy (clay) soils. Suitable pH: acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It prefers moist or wet soil. Zone 4-9.
