What is ulm parvifolia?
Ulmus parvifolia , most often known as the Chinese elm, is a resistant tree with a small trunk, a vase -shaped profile and a distinctive exfoliating bark that gives it a spotted multicolored look. This diversity of ELM comes from China, Korea, Vietnam and Japan and has been grown around the world and first appeared in Europe during the 18th century. Its small, serrated leaves that spread to a wide canopy of finely suspended branches can remain in a warmer climate evergreen, but in most regions it is deciduous. Even in a colder climate, however, the ulmus parvifolia may remain on the tree since the first time in March until December or January puddle. In these colder areas, the colors of the leaves change at the end of the autumn and move from their usual dark green to a diverse palette, including shades of purple, yellow and red.
capable of prosperity in most soils is ulMus Parvifolia a robust, fast -growing tree that requires little care and maintenance usually includes nothing but the connection of the new tree to the bet to stimulate it straight. The tree grows well in the urban and suburban environment and can prosper in areas where air pollution, drought and poor drainage are present. It is more resistant to the Dutch ELM disease than other ELM species and in some regions it replaces the original ELMS that fell to this disease. ulmus parvifolia is able to grow to heights of 80 feet (24.4 m) tall, but ripe trees usually range from 40 to 50 feet (12.2 to 15.2 meters). Thanks to these functions, the tree has become a popular choice for landscaping along residential streets, courtyards and squares and on the islands of parking lots.
most ELM trees will be flowing in spring and produce seeds, but ulmus parvifolia bears fruit until late autumn. Tje's fruit, called Samara, has a paper wing ranging from the fruit and resembles a helicopter blade. FaceSamary allows it to be easily transmitted by the wind, allowing the seed to grow from the superior tree.
In some areas of the world, it has become too effective when spreading seeds. In South Africa, for example, the tree has become invasive and has a harmful effect on the indigenous life of plants. This invasive tendency has also been recorded in parts of North America and Australia, though not to the same extent.
