Why it’s bad With its close relative Morning Glory (Ipomoea indica) among our worst smothering vines, widespread, fast-growing.

Control Hard to eradicate because trailing and broken sections of stem can sprout from nodes. Mature plants need to be traced back to the base, cut and poisoned.

Alternatives Replace with Scrambling Lily (Geitonoplesium cymosum). Also useful would be Native Wistaria, Round-leaf Vine, Native Passionfruit, Embelia, Pearl Vine, Native Jasmine.
