Hibiscus

The flowers are 4 to 8 inches (10 to 20 cm) wide and have a whorl of 5 egg-shaped, toothed or smooth-edged petals that are fused at the base to the central column. The central staminal column is tipped with a 5-lobed style above multiple yellow anthers near the tip of the column. The wild-type plants have single, red flowers, but the cultivated varieties can have single or double flowers in a wide variety of colors. The flowers attract nectar-loving birds like Japanese White-eyes (Zosterops japonicus). The leaves have pinnate veins and are green, coarsely toothed, alternate, and oval-shaped with a pointed tip.
