and fruit size, ranging from 10 to 60. The seeds are about 2 mm long, 1 mm wide, yellowish, compressed with a curved embryo.


Reproduction

The plants are self-pollinating, but may be cross pollinated by insects. The species is dispersed into natural areas by birds and other animals that eat its fruit. In the Northern Hemisphere, flowering occurs from June through September and berry maturation from August to October, depending on the latitude, altitude, and climate. Where frost does not occur fruiting is continuous and plants do not lose their leaves.
