Oenanthe

 

a genus of plants of the family Umbelliferae. They include perennial, annual, and biennial herbs with pinnatisect leaves. The flowers are white or pale pink, and the fruit has a thick, spongy pericarp. There are approximately 40 species, distributed primarily in the temperate zones of Europe and in the mountains of tropical Africa. About 11 species are found in the USSR, growing mainly in damp areas. Particularly widespread is the fine-leaved water dropwort (O. aquatica), which grows in marshes, along canals, on the shores of bodies of water, and in shallow standing or sluggish waters. There are terrestrial and aquatic forms, the latter having submerged leaves. All parts of the plants are poisonous, particularly the roots. The plants have been known to posion cattle, horses, and sheep.

Beginning in April 1993, Oenanthe javanica was propagated by the author.
Therefore, to estimate the nutrient removal potential of Oenanthe javanica, the composition of stems and leaves of sample plants removed from the plant/rock filter during the study period was determined.
For this field study, two components were monitored: winter growth of Oenanthe javanica and performance of the plant/rock filter.
Vigorous growth of Oenanthe javanica in winter should allow quick establishment of complete plant cover and full-depth root penetration in plant/rock filters, even when the plants must be planted late in the year.
Further decline in number of plants is not anticipated as Oenanthe javanica is a perennial and the plants were well established by the end of the study
Oenanthe javanica was planted directly into the gravel and grew well, proving that this potentially detrimental layer is unnecessary with this plant.
