Neoalsomitra sarcophylla is a perennial climbing vine belonging to the Cucurbitaceae family, notable for its caudex—a swollen, woody base that stores water. This adaptation, along with its trifoliate, fleshy leaves, makes it well-suited for easy care in indoor cultivation.

Native to

This species is indigenous to Southeast Asia, including countries such as Thailand, Myanmar, Laos, Cambodia, and Vietnam. In its natural habitat, it thrives in mixed, partly deciduous evergreen lowland and montane forests, often on basalt, granite, or limestone bedrock, at altitudes up to 850 metres. 

Water

Neoalsomitra sarcophylla prefers occasional watering, allowing the soil to dry out between waterings. Overwatering can lead to root rot, so it's essential to ensure the potting mix offers excellent drainage. During the growing season, water more frequently, reducing the frequency in autumn and winter. 

Light

This plant thrives in mostly sunny conditions. Placing it near a south-facing window can provide the necessary light intensity. However, in the UK, where light levels can be lower, supplementing with artificial grow lights may be beneficial, especially during the shorter days of autumn and winter. 

Humidity

While Neoalsomitra sarcophylla can adapt to average indoor humidity levels, it benefits from a slightly more humid environment, similar to its native habitat. Maintaining humidity levels around 60% can promote healthy growth. This can be achieved by placing the plant on a tray filled with water and pebbles, ensuring the pot's base doesn't touch the water, or by using a humidifier.

Temperature

Maintain indoor temperatures between 18°C and 27°C (65°F to 80°F) for optimal growth. Avoid exposing the plant to temperatures below 15°C (60°F), as prolonged exposure to cold can cause stress and damage. Keep the plant away from drafts and sudden temperature fluctuations to ensure its well-being.
