Introduction to Ibervillea Plants
Ibervillea family is native to the Sonoran and Chihuahuan Deserts and have a range from Texas, through western Mexico, to Baja California. Its growth habit is to form a large tuber, mostly underground, and be topped with crawling seasonal vines. The tuber can grow to 2 feet wide (75cm), and some species of Ibervillea root are used to treat diabetes. It is active during the warm months when watering is fine. When it drops its leaves and vines slow watering to a craw. Some species can withstand frost, while others are pretty tender. Several species should be of interest to Caudex collectors.
