Dioscorea communis BLACK BRYONY (10 seeds)

Black Bryony, also known Tamus, or Dioscorea communis, is a climbing plant belonging to the yam family (Dioscoreaceae). It is a common woodland plant native to Europe, Asia, and North Africa. In various regions, it is known by names such as "Devil’s Grapes" or "Black Vine," and it can grow several meters per year.

The leaves are a deep, shiny green, heart-shaped (cordate), and can reach up to 15 cm in length. They have a smooth texture and are arranged alternately along the stems.

Its flowers are small, discreet, and white to greenish, appearing in clusters during the summer. Each flower is star-shaped with six petals.

The fruits are bright red, globose berries that contrast sharply with the green foliage. They measure about 1 cm in diameter and are attractive to birds; however, they are highly toxic to humans and must never be consumed.

Black bryony seeds are gray, rounded, and average 2 to 3 millimeters in diameter.

- Properties / Uses:

In certain regions, the young shoots are harvested in the spring and consumed like asparagus. While they have an extremely bitter flavor, they are traditionally eaten after long cooking, which almost entirely removes the bitterness.

Historically, the plant was used in folk medicine for its diuretic, and anti-epileptic properties. The root was grated and applied topically to treat bruises. A traditional ointment for rheumatism involved boiling the root for 2 to 3 hours and mashing it with lard. Warning: Contact with ripe berries or rhizomes can cause dermatitis due to calcium oxalate crystals penetrating the skin.

As a climber, it is excellent for covering trellises and pergolas to create shade. Do not consume without medical advice; grow only as a collector's plant.

- Germination and Sowing Seeds:

• The best period to sow Black Bryony is from March to late April to benefit from the cool climate for natural stratification.
• Artificial Stratification: You can leave the seeds in the refrigerator for 4 to 6 weeks.
• Sow seeds 0.5 cm deep in a fine, well-draining potting soil.
• Tamp the soil lightly and water gently with a spray bottle.
• Place the culture in a warm greenhouse environment between 15 and 20°C.
• Germination is relatively slow, taking 3 to 5 weeks on average after stratification.

- Soil Type / Substrate:

The soil should be rich and well-draining. It thrives in moist terrains with a light texture and good water retention. It is frequently found in forests and along hedgerows in Southern Europe.

- Exposure:

It prospers in varied conditions but prefers partial shade to full sun. Indirect light promotes healthy growth without excessive water stress during heatwaves.

- Temperatures / Hardiness:

This plant is quite hardy and adapts to a wide range of temperatures, with optimal growth between 15 and 25°C. While frost may damage the foliage, the plant is capable of regrowing from its base at the start of spring.

- Irrigation / Water Needs:

Watering should be regular, especially during dry spells. Maintain a slightly moist soil without saturating it, as excess water can cause root rot.

- Multiplication / Propagation:

It reproduces primarily via seeds, but it can also be propagated through cuttings during the vegetative period in summer.

- Pests / Diseases:

Black Bryony can be preyed upon by various herbivores, including insects and rodents. It may also be affected by fungal diseases or pests like aphids.
