It is an aquatic plant whose name is often used to define very thin and slender people. Indeed, this species has a slender appearance, but with a graceful bearing. In its various varieties, always the species we are about to talk about, it allows the creation of highly decorative aquatic spaces. Some varieties of the aforementioned plant have no blooms to remember, especially because the appearance of the flowers is nothing exceptional. However, the plant, with its slender and supple posture, excellently decorates all aquatic spaces, both the natural ones, where it develops spontaneously, and those of the garden, where water ponds can be created by combining different plants suitable for growth under the water surface. As we have no intention of launching a quiz game in this article, we immediately reveal that we are talking about the rush, an aquatic species that grows in almost all containments. In the following paragraphs we will focus on the characteristics of the rush, on the main varieties and on the techniques for its cultivation.


The rush includes more than 200 aquatic species belonging to the Juncaceae family. These plants are widespread in humid places all over the world. In fact, they grow near rivers, lakes, ponds and marshes. For their development they need water, no matter if clear or dirty. Some varieties of June also grow well in the undergrowth, where rain and the fall and decomposition of plant material create small surface ponds suitable for the development of this species. The rush is a plant with a long green stem, one hundred and twenty centimeters to two meters high. There are also dwarf varieties that do not exceed ten centimeters in height. The stem is flat or cylindrical, surrounded by thin leaves of the same color and the same shape. The flowers are generally green or brown in color and have the shape of a fan. The fruit is a capsule that contains the seeds. The flowering period of the rush varies according to the variety, as well as the shape of the flowers and the ornamental yield of the plant. There are species of rushes that produce very beautiful flowers and that are grown in water gardens for ornamental purposes. The rush belongs to the perennial herbaceous species with a bushy habit.


In nature there are about two hundred and twenty-five species of rushes, widespread in every corner of the world: from Europe, to America and Asia. It would be impossible to list all the varieties of rush, so we will limit ourselves to indicating the best known and cultivated ones. Among these we remember the Juncus effusus, also called common rush, the Butomus umbellatus, or flowery rush, Juncus maritimus, also called maritime rush, juncus bulbosis, juncus acutus, junkus cuckoo, juncus capitatus and juncus biflorus. The juncu effusus, or common rush, is the best known and cultivated species among those we have just mentioned. It can reach a height of one and a half meters and has small leaves and flowers. The flowering rush is an aquatic species native to Europe, America and Asia. It has dark green ribbon-like leaves and small pink flowers that develop from an umbrella-shaped inflorescence from which the botanical name of the species derives, that is Butomus umbellatus. The juncus maritimus or maritime is similar to the common rush and develops in places of the sea, that is, in the presence of salt water. The juncus bulbosis is about sixty centimeters high, has a stem that develops in an upright position and which transforms it into a rush with a high ornamental effect. The juncus acutus is also known as thorny rush, has a bushy habit and can reach a height of two meters. The juncus cuckoo is similar to the common rush, but the stem and leaves are streaked with green and yellow. The juncus capitatus, on the other hand, is a dwarf annual species that does not exceed ten centimeters in height.


In general, the rush blooms in the summer, producing green or brown fan-shaped flowers. The flowers can also have a different coloration which depends on the variety from which they grow. In the flowering rush, for example, the flowers are pink, and appear in summer, while in the biflorus variety they are red and bloom in spring.
