Cyphostemma montagnacii seeds
Discover the exceptional Cyphostemma montagnacii seeds, a rare and captivating caudiciform succulent native to the arid regions of southwestern Madagascar, particularly near Toliara (Tuléar) and the Onilahy River basin 25. This perennial herbaceous plant, known locally as “Mangeboka” (meaning “maintaining”), is prized for its massive, inverted conical caudex that can reach up to 30 cm in diameter and store over 50 liters of water, acting as a natural reservoir during droughts 25. The caudex produces short, flexible vines up to 1.5 meters long that climb surrounding vegetation, adorned with succulent, sessile, 3-foliate leaves and multi-branched cymes of greenish-yellow flowers 23. From November to March, the plant completes its rapid vegetative cycle, culminating in edible, sweet fruits that ripen by February 25.
Ideal for succulent enthusiasts, caudex collectors, and conservationists, Cyphostemma montagnacii thrives in well-draining, limestone-rich soil mimicking its native habitat 23. It prefers full sun to light shade and requires moderate watering during the growing season (November to March), allowing the soil to dry slightly between sessions. Reduce watering significantly during dormancy (April to October) to prevent rot 3. This species is hardy in USDA zones 10-11 and should be protected from frost. Fresh seeds germinate best at temperatures of 20°C–25°C (68°F–77°F) when sown in a sandy, well-draining medium, though germination can be slow and may take several weeks 3.
⚠️ Note: While the fruits are edible and sweet, the seeds and other parts may contain irritants; handle with care and keep away from children and pets 2.
Each seed order includes a detailed germination guide. Due to its critically endangered status (with only 25 individuals per hectare in the wild), cultivating Cyphostemma montagnacii from seeds supports urgent conservation efforts and helps preserve this species from habitat loss and over-collection 5.
