Ciclospermum leptophyllum is worthy of note that this plant (in common with others of the genus) is sometimes acrid and injurious when grown in damp soils. It is, doubtless, capable of much improvement by careful cultivation. This plant is not endemic in Australia."

North of the alps wild celery is found only in the foothill zone on soils with some salt content. It prefers moist or wet, nutrient rich,
