Why it’s bad
With its close relative Morning Glory Ipomoea indica is among our worst smothering vines, widespread, fast-growing.
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.
Replace with Scrambling Lily Geitonoplesium cymosum. Also useful would be Native Wistaria, Round-leaf Vine, Native Passionfruit, Embelia, Pearl Vine, Native Jasmine.
