Geographic Distribution and Habitat –
The tenacious rush is a species with a vast Eurasian distribution and present, in Italy, in all regions. It is also found in North Africa.
Its habitat is that of pioneer humid vegetation on the edge of paths, ditches, ponds and drinking troughs, on clayey-clayey compacted and periodically submerged soils, rich in bases and nitrogen compounds, from sea level to the mountain belt.
Juncus inflexus is a bushy plant formed by dense dark gray-green stems.
On the tops of the stems, during the summer, it produces brown-brown inflorescences composed of several branches.
The fruit is a 2.5-3.2 mm loculicidal capsule, ovoid or ellipsoid, trigone, subacute-mucronate, with a 0.2 mm beak, brown or brown-dark, glossy in the upper part. Seeds of 0.5-0.6 mm, ± ovoid or ellipsoid, covered with a fine reticule, reddish.
The tenacious rush is a plant that blooms in the period of May – July.
It can be used for phytodepuration plants or as a plant at the edges of small reservoirs to keep the waters clearer.
The planting depth between the rhizome and the water surface ranges from 0 to -5 cm.
The height of the plant above the water level must be about 60 cm.
The plant prefers full sun exposure and is very resistant to low temperatures.
Customs and Traditions –
Juncus inflexus is a sheared bushy marsh plant which is however toxic for livestock.
This plant is suitable for swampy areas with a few cm of water, or for moist soil.
Juncus inflexus is a plant also used for phytodepuration alone or together with other plants with identical needs.
Preparation Method –
The Juncus inflexus as well as plants for phytodepuration has no particular uses neither food nor therapeutic.
