Bryonia cretica DEVIL'S TURNIP (10 seeds)

White Bryony, also known as Devil's Turnip or Bryonia cretica in Latin, is a perennial herbaceous plant native to Europe and a member of the Cucurbitaceae family. It is a fast-growing climbing plant typically found in hedgerows, reaching about 3 meters in height and producing red and black berries.

It features characteristic foliage composed of large, palmate, lobed, and heart-shaped leaves. These deep green leaves can reach impressive sizes, sometimes up to 20 cm wide. Their texture is generally smooth, and they are arranged alternately along the stems.

The bloom is a sight not to be missed. The flowers, usually white or greenish, gather in axillary or terminal clusters. They have a star-like shape with finely cut petals, giving them a delicate appearance. The flowering period often extends from summer to autumn, attracting many pollinators, especially bees. The flowers are followed by small spherical fruits.

Its roots are fleshy and robust, digging deep into the soil to draw necessary nutrients. They have a tuberous shape, allowing the plant to store water and nutrient reserves, providing resistance to difficult environmental conditions.

White Bryony seeds are hard, dark brown speckled with light brown, and round in shape.

A classic botanical curiosity

Sowing Bryony seeds from Ethnoplants allows you to introduce a spectacular climbing plant into your garden, featuring delicate tendrils and vigorous growth. Nicknamed the "Devil’s Turnip" due to its massive, impressive tuberous root, it is an iconic figure of the European wild flora.
By germinating your own specimens, you cultivate a centerpiece of botanical history, whose red berries and lobed foliage bring a wild, authentic structure to your fences or cottage gardens.

A fascinating subject for botanists

The White Bryony is a fascinating species due to its complex organic composition, particularly its richness in saponins, which give it unique biological characteristics.
Within the history of botany, this plant has long been documented in ancient herbariums for its distinct traits.
It remains an essential collector's species for those wishing to document the wild plant heritage and species with significant growth characteristics.

- Germination and Sowing:

• The suitable period to sow Devil's Turnip starts from late April until early June.
• Sow the seeds in a tray or a large pot filled with horticultural potting soil.
• Bury them 0.5 cm deep.
• Water the culture gently.
• Place the pots or tray in a greenhouse at a temperature between 20 and 25°C.
• Germination generally begins 3 to 4 weeks after sowing.

- Substrate / Soil Type:

It prefers well-drained, humus-rich soils. A mix of garden soil and compost is perfect for its development. It can adapt to different soil types, but slightly calcareous (alkaline) soil is ideal for its growth.

- Exposure:

This variety appreciates full sun to partial shade. Good sunlight promotes flowering and lush foliage, while partial shade is tolerated, especially in hotter regions.

- Temperature / Hardiness:

Its cold resistance is good, as it can withstand temperatures down to -7°C. However, it thrives best in temperate climates with temperatures between 15 and 25°C. It can be sensitive to late frosts, which may affect its growth.

- Watering:

The plant requires regular watering, especially during dry spells and at the time of planting. It is important to keep the soil slightly moist without overwatering, as this could lead to root issues. Mulching can help retain soil moisture.

- Propagation:

Its modes of reproduction are by seeds and also by cuttings, by taking stem fragments starting in late summer.

- Pests and Diseases:

While generally resistant to diseases, it can be subject to attacks by aphids, spider mites, and mealybugs. Preventive treatments, such as using black soap, can help protect it from these pests.
