Siratro

Macroptilium atropurpureum is a tropical herbaceous dicot belonging to the ‘Fabaceae’ family. Macroptilium atropurpureum rapidly develops dense dark hairy green vines approximately 5 mm in diameter, until it reaches its mature size of approximately 120 centimetres. The vines have bright green trifoliate leaves, which are approximately 2-7 centimetres long with smooth hairs on the underside. Flowers are dark reddish purple. The seeds are small brown peas with a white spot, found in the plant's pods which hang on the vines in bunches of about 5-10. In weather and soil conditions favourable to the plant, stem nodes close to the soil may root, enabling vegetative propagation of the plant. Macroptilium atropurpureum forms a deep swollen taproot up to 2 centimetres in diameter.
