Key Features: Stephania Kaweesakii

• Growth Type: Deciduous caudiciform vine.
• Caudex: Large, rounded to irregularly shaped caudex that stores water and nutrients.
• Vines: Slender, twining stems that emerge from the caudex each growing season.
• Leaves: Attractive, nearly circular, peltate leaves with radiating veins, giving the plant a distinctive ornamental look.
• Flowers: Tiny, greenish-yellow flowers that appear in clusters, followed by small red fruits on female plants.
• Size: The caudex can grow over 30 cm (12 inches) in diameter with age, while the vines may extend several meters if supported.

Caudex Pattern

Young plants develop a smooth, rounded caudex that gradually becomes:

• Thick and woody
• Rough and fissured with age
• Highly sculptural, making mature specimens especially desirable

Many growers partially expose the caudex above the soil to showcase its unique form.

Growing Conditions

Light:
Prefers bright indirect light to partial sun. Morning sunlight encourages healthy growth while protecting the foliage from intense afternoon heat.

Soil:
Requires a well-draining mix, such as:

• 50% cactus or succulent mix
• 25% pumice or perlite
• 25% coarse sand or grit

Watering:

• Water regularly during active growth (spring and summer).
• Allow the soil to dry slightly between waterings.
• Reduce watering significantly during dormancy when the vines die back.

Temperature:

• Ideal range: 20–35°C.
• Protect from temperatures below 10°C.

Growth Cycle

• Spring: New vines emerge from the dormant caudex.
• Summer: Vigorous climbing growth and leaf production.
• Autumn: Growth gradually slows.
• Winter: The plant enters dormancy and sheds its vines and leaves.

Care Tips

• Provide a trellis or support for climbing vines.
• Grow in a shallow clay pot to display the caudex and improve drainage.
• Fertilize monthly with a diluted balanced fertilizer during the growing season.
• Avoid overwatering during dormancy to prevent rot.

Propagation

• Seeds: The preferred method, producing plants with naturally developed caudices.
• Caudex division: Rarely practiced and generally not recommended.

Uses

• A prized specimen for caudiciform collections.
• Excellent for bonsai-style displays.
• Ideal for decorative containers and bright indoor spaces.
