Habit:
Island Morning Glory is a perennial vine. The thin stems wrap helically around neighboring plants. The arrowhead-shaped leaves faintly show veins and ribs in lighter color. This species has six subspecies with overlapping ranges.

This wild perennial is related to the gardener's Morning Glory, which is annual and has larger heart-shaped leaves. Similar species: Pacific false bindweed aka Morning Glory [C. purpurata]. The other vine in BMER, Wild Cucumber, is much larger.
