The knotty knotweed ( Persicaria capitata , syn .: Polygonum capitatum ), also known as knotweed knotweed, is a plant from the knotweed family . The species is cultivated as a ground cover in gardens.
description
The plant is annual to perennial, depending on the climatic conditions. It grows prostrate, whereby the 5 cm to 50 cm long stems can root at the nodes. The plants reach heights of growth of 10 cm to 20 cm.
The only a few millimeters long stalked leaves are usually 3 to 4 cm long and oval to elliptical. Their base is narrowed in a wedge shape. They are briefly pointed at the front. The leaf margin is provided with a narrow red and hairy border. The leaves often have a semicircular to V-shaped reddish markings on their blades. The approximately 1 cm long reddish-brown ochrea is cylindrical.
The inflorescences are characteristic. These sit at the end on ascending side branches, are stalked up to 4 cm long and approximately spherical with a diameter of usually 1 to 2 cm. The flower color varies between whitish-pink and reddish.
Distribution and location requirements
The plant originally comes from the Himalayas (northern India , Nepal , Bhutan , China ) or from Indochina and Malaysia. But it was introduced as a garden plant in many parts of the world. In tropical and subtropical areas as well as temperate regions with mild winters it regularly overgrows and can then be found frequently on cultivated land, especially in stony, dry places.
