A remarkable drought-tolerant succulent native to Southern Africa from the Cucurbit family (cucumber family), bearing a silver-brown pumpkin-like caudex, which can potentially grow up to 40cm in diameter. It produces long trailing shoots with branched tendrils, and is able to climb as high as 8m. The smooth, ivy-shaped leaves are shiny and prominently veined. Interestingly, male and female flowers are produced on separate plants, and the fruit is said to resemble a sea cucumber. Prevent the soil from drying out completely when caring for them, when grown in containers always keep it slightly moist but not wet. The only danger here is if water can't drain out from the pot, this leads to rotting of the caudex. Prune shoots as needed to keep the plant in control and pinch the young growth to promote bushier plant. It tolerates full sun and partial shade.

Light: Place the plant in a well-ventilated area whereby it can receive more than 6 hours of bright (preferably indirect) sunlight daily.

Water: Once every two-three days, water the plants thoroughly till excess water drains out of the pot. Do not allow the potting substrate to dry out completely.

Temperature: Plant tolerates temperatures from 18-32°C.

Fertilizer: An all-purpose, water-soluble balanced fertilizer that contains an equal amount of nitrogen, phosphorus, and potassium (e.g. N-P-K: 15-15-15 +TE) will help to boost the plant's overall health by feeding it every two weeks. Otherwise, a slow-release fertilizer (e.g. Osmocote) can be incorporated into the potting media, and to be replenished after about 2-3 months. Do follow the recommended dosage indicated on the fertilizer’s application instructions.
