Momordica Rostrata
IntermediateMomordica rostrata
A cucurbit caudex with white bark-like tuber producing vines and red fruits.
About
Momordica rostrata is native to dry regions of East to southern Africa in the Cucurbitaceae family. Its caudex is covered in distinctive white to pale gray bark-like skin with a rough texture. Twining stems with divided leaves emerge from the caudex. Small white to yellow flowers are followed by striking red to orange fruits that are ornamentally appealing but toxic and should not be consumed. Growth is vigorous during the growing season, as expected for a cucurbit. Full sun to bright partial shade with well-draining soil is appropriate. Generous watering from spring through autumn gives way to complete drought in winter. It is somewhat frost-sensitive. The contrast between the white caudex and vivid red fruits makes it an eye-catching choice for collectors seeking unusual caudex plants.

Growing Tips
Light & Placement
Grow in full sun to bright partial shade. The vines grow vigorously in the growing season, so a support to climb on makes management easier.
Watering
In the spring-to-autumn growing season, water thoroughly once the soil dries. As growth slows in autumn, reduce frequency in preparation for the winter dry period.
Temperature & Overwintering
Cold tolerance is somewhat low and frost damages it, so bring it indoors for winter. Withhold water and overwinter it dry.
Soil & Repotting
Use a well-draining mix such as akadama blended with pumice. Plant with the upper part of the caudex above the soil surface.
Pests & Cautions
The red-to-orange fruits are toxic and must not be eaten. Choose the location carefully in homes with pets or children.
