Summary

Calystegia macrostegia, commonly known as Island False Bindweed, is a woody perennial herb or small shrub. It can take the form of a low herbaceous vine or a stout, woody, climbing plant, which can reach lengths of up to 9 meters (30 ft). This species is native to coastal sage scrub and chaparral habitats, as well as riparian zones in California, particularly on the Channel Islands. The leaves are triangular and can be over 10 centimeters wide. The vine produces showy white to very pale pink to lavender blooms, which can vary in color intensity depending on environmental factors such as drought or temperature. Flowering occurs from spring through summer, attracting native bee species and serving as a valuable pollinator plant.

Island False Bindweed is valued for its versatility as an ornamental plant, used both as a climbing vine and groundcover in native plant gardens, drought-tolerant landscapes, and wildlife gardens. Its ability to thrive with medium amounts of water and in soils with medium to fast drainage makes it suitable for cultivation in a variety of garden settings. While it prefers full sun, it can also tolerate part shade, which makes it adaptable to different garden designs. Gardeners should note that while it is generally low-maintenance, it can become aggressive in favorable conditions and may require regular pruning to keep it in check.CC BY-SA 4.0
