About Dioscorea orientalis
Dioscorea orientalis, commonly known as Black Bryony, is a perennial climbing plant with twining stems that can reach several meters in length. Its heart-shaped leaves are bright green and often glossy, while its red berries, though attractive, are toxic. It is ideal for covering pergolas, fences, or walls in natural or wild-style gardens, adding a rustic and decorative touch.
Native range

Care tips
It prefers locations with partial shade or dappled sunlight, tolerating some direct sun if the climate is not excessively hot. Watering should be regular, keeping the substrate moist but not waterlogged, especially during its active growth period. It requires fertile, well-drained soil rich in organic matter. A common mistake is underestimating its toxicity; ensure it is kept out of reach of children and pets, and wear gloves when handling it.
