Urtica species grow as annual plants as perennials, rarely trees. Depending on the type, location and nutritional level, they can be 10-300 inches (3.9-118.1 inches) long. The perennial species has rhizomes underground. The green parts have feathers. Typical square trunks have no branches or twigs, are upright, ascending or spreading. Most of the shoulder blades and stems are arranged on opposite sides of the trunk. The leaves are elliptical, lanceolate, oval or round. The petals are usually three to five, rarely up to seven years old. The blade blade is usually serrated into more or less strong teeth. The leaves of perennial shoots are often loose or joined together. Cystolites expand into more or less circular ones. In 1874, while in Collioure (southern France), the French botanist Charles Naudin discovered that a strong wind for 24 hours had made Urtica ferries innocent for a week.
