The Texas bindweed (Convolvulus equitans) belongs to Convolvulaceae (the Morning glory family). It is an annual herb that is distributed from the central to western parts of the United States and Mexico. It grows in grasslands and disturbed areas, and can grow to be around 1.8 m long, climbing up other plants as it grows. The leaves vary greatly in shape, from ovate to triangular-lanceolate to narrow oblong, depending mainly on the intensity of sunlight. The leaf edges can be entire, wavy or divided into 1 to 3 lobes. From spring to fall, funnel-shaped flowers bloom from the leaf axils, ranging from white to pink. The diameter of the corolla is about 3 cm, and sometimes the center is tinged red or rose.
