Male flowers have stamens about 3 mm (0.12 in) long with a sterile carpel about 0.3 mm (0.012 in) long. Female flowers lack stamens and usually have a single carpel about 1.5 mm (0.059 in) long. Flowering occurs in summer and the fruit is a spherical red or brown to black follicle 6–7 mm (0.24–0.28 in) wide. [4] [5]
