BeginnerIbervillea sonorae
A Mexican cucurbit caudex with large green tuber producing vines, hardy for beginners.
About
Ibervillea sonorae is native to dry regions of Sonora state in Mexico through southern Arizona, belonging to the Cucurbitaceae family. It develops a large, green-tinged spherical to oblate caudex exposed above the soil—the green color indicating chlorophyll-containing tissue capable of photosynthesis. Divided, cucurbit-type leaves emerge on twining stems that extend vigorously during the growing season. Small yellow flowers are followed by red fruits that are toxic. Growth is relatively fast and the plant is robust and forgiving. Full sun to bright partial shade with well-draining soil is appropriate. Generous watering from spring through autumn and complete winter drought are standard. Cold tolerance is reasonable. Its accessibility, affordability, and ease of culture make it an ideal starting point for Mexican cucurbit caudex collecting.
