Bryonia cretica ssp. dioica (red bryony)

Red bryony is native to central and southern Europe, as well as northern Africa and western Asia. All parts of the red bryony are toxic. The plant is fast growing, with climbing tendrils, and can reach over three meters in height. It is a very deep-rooted plant. The species is perennial and flowers from May to June with white or greenish-white, quite small flowers. The red bryony was historically used to treat rheumatic conditions and has antiviral effect but is due to its toxicity advised to be avoided nowadays. 

This plant is dioecious, meaning individual flowers are either male or female. Both male and female plants must be cultivated when producing seeds. Red bryony is not self-fertile, and insect pollinated. It can grow in semi-shade or sunny settings and neutral or slightly alkaline, moist to well drained soils.

The seeds are best sown as soon as they are ripe, or in late winter in a cold frame or a tray outdoors. The seeds might need a cold period to germinate. Initially sow the seeds in tray substrate and cover the seeds slightly. When large enough to handle transplant the plants into small individual pots in pot substrate.

The pots can be placed in an unheated greenhouse, or outside when the risk of frost weather is over. When fully rooted in the pots, plant outside in field. The vine produces a berry, initially green, then turning yellow and when red, the berries are mature. Always harvest in dry conditions. Seed harvest will probably be obtained August/September during the second year of cultivation. Harvest the berries when they are fully red.
