Quick facts

About Slender celery

Cyclospermum leptophyllum, commonly known as Marsh Parsley or Mølleselleri, is an annual herb belonging to the Apiaceae family, characterized by its finely divided leaves and delicate appearance. It produces small white flowers in compound umbels, followed by tiny fruits. This unassuming plant can grow as a weed in gardens or as part of a low-maintenance, wild-looking landscape.

Native range

South America, particularly Chile and Argentina.

Care tips

This species prefers full sun to partial shade and adapts to a wide range of soils, though it favors well-drained and slightly moist ones. Watering should be moderate, allowing the substrate to dry out slightly between waterings, and it is not demanding in terms of nutrients. A common mistake is to confuse it with other umbellifers or underestimate its self-seeding capability, which can lead to unwanted proliferation if not controlled.
