Desmodium tortuosum (Sw.) DC.
Desmodium tortuosum, commonly known as Florida Beggarweed, is a perennial.
Desmodium tortuosum was already described and the name validly published by Olof or Olavo Swartz. It was Augustin Pyramus de Candolle, however, who reclassified it into todays valid botanical systematics in 1825.
The perennials reach heights of 50 to 200 centimetres, the main growing season is in spring and summer. They have a erect habit and are comparatively fast-growing.
Desmodium tortuosum is deciduous. The dark-green, ternate leaves are alternate. The ovate leaflets are petiolate.
Flowers and Fruits
Desmodium tortuosum produces racemes of showy, salmon-red pea-shaped flowers from June to September.
From autumn to winter the perennials produce an abundance of ornamental brown loments that are persistent on the plant.
Desmodium tortuosum is native to Florida and the West Indies.
The perennials prefer a sunny situation. The substrate should be comparatively poor with a pH between 5 and 7,2. The plants need a soil depth of at least 15 centimetres for good growth. They need a frost-free period of at least 17 weeks.
