The alternate leaves of this plant are divided into three heart-shaped leaflets that can grow up to 2 cm wide. Somewhat resembles clover in this regard. These leaves curl up at night, and open in the day to perform photosynthesis. The mature seed capsules open explosively when disturbed and can disperse seeds up to 4 meters away.
It tends to grow as a weed in gardens and lawns, found in woodlands, meadows, and in disturbed areas as both a perennial and annual. Blooms from July to October.
