Family: Vitaceae

Origin, Description & Uses
Cyphostemma juttae (Namibian grape, tree grape, wild grape) is a striking, drought-adapted succulent shrub native to rocky desert regions of Namibia and adjacent parts of southern Africa. Despite its common name, it is not a true grape but belongs to the grape family (Vitaceae). This sculptural plant develops a thick, swollen trunk (caudex) and stout, upright branches that can reach up to 6 feet tall. Its large, rounded, gray-green leaves are often edged in red, and it produces clusters of small yellowish flowers followed by bright red, grape-like fruits. Well suited to dry climates and coastal gardens, Cyphostemma juttae is valued as an ornamental specimen plant for xeriscaping, rock gardens, and container culture. It is especially appreciated for its dramatic form and ability to thrive in poor, well-drained soils with minimal water.

Risks, Threats & Management
Cyphostemma juttae is considered a Low Risk species. It is slow-growing, adapted to arid conditions, and does not typically spread aggressively. While it produces fleshy fruits that may be eaten by birds, there is no evidence that it forms invasive populations in tropical island ecosystems. Its growth requirements—excellent drainage and dry conditions—naturally limit its ability to establish in wetter environments. As with any introduced plant, responsible cultivation is recommended. Gardeners should monitor for unwanted seedlings and avoid planting near sensitive natural areas. With proper management, this distinctive desert plant can be enjoyed in appropriate landscape settings without posing a significant ecological threat.

High Risk Traits:

• Seeds possibly dispersed by birds and intentionally by people

Low Risk Traits:

• No reports of invasiveness or naturalization
  
• Unarmed (no spines, thorns or burrs)
  
• Ornamental
  
• Not reported to spread vegetatively
  
• Long time to reproductive maturity
