Cambodian Wild Grape Ampelocissus Martini
Ampelocissus martini, commonly known as the Cambodian Wild Grape, is a rare and highly sought-after caudiciform vine native to Cambodia, Thailand, Laos, and parts of Vietnam. It belongs to the grape family (Vitaceae) and is prized for its impressive swollen caudex and vigorous climbing growth.
Key Features
- Growth Type: Deciduous caudiciform climber.
- Caudex: Large, woody, potato-like caudex that stores water and nutrients.
- Vines: Fast-growing climbing stems that emerge during the growing season.
- Leaves: Large, attractive green leaves with serrated margins, resembling grape leaves.
- Flowers: Small, greenish-yellow flowers produced in clusters.
- Fruits: Small grape-like berries that turn dark when mature.
Caudex Pattern
Young plants develop a rounded, smooth caudex that gradually becomes:
- Thick and corky
- Deeply fissured and textured with age
- Irregular and sculptural, making mature specimens highly desirable among collectors.
The exposed caudex can eventually reach 20–50 cm (8–20 inches) or more in diameter under ideal conditions.
Growing Conditions
Light:
Prefers bright indirect light to partial sun. Mature plants can tolerate morning or filtered direct sun.
Soil:
Requires a very well-draining mix, such as:
- 40% cactus mix
- 30% pumice or perlite
- 30% coarse sand or grit
Watering:
- Water regularly during active growth (spring and summer).
- Allow the soil to partially dry between waterings.
- Reduce watering significantly during dormancy after the leaves drop.
Temperature:
- Ideal range: 20–35°C.
- Protect from temperatures below 10°C.
Growth Cycle
- Spring: New vines and leaves emerge.
- Summer: Vigorous climbing growth.
- Autumn: Growth slows.
- Winter: Plant becomes dormant and may lose all leaves.
Care Tips
- Provide a trellis or support for the climbing vines.
- Grow in a shallow clay pot to showcase the caudex.
- Fertilize lightly during active growth with a balanced fertilizer.
- Avoid keeping the soil wet during dormancy.
Propagation
- Seeds: Produce the best caudex development.
- Stem cuttings: Possible but usually result in less impressive caudex formation.
Uses
- Collector's caudiciform specimen.
- Bonsai and caudex display plant.
- Excellent for creating dramatic container displays with exposed roots and caudex.
