Ipomoea Indica - Morning Glory

 

​

Habitat

Originating in the tropics, this twining vine grows vigorously, especially in moist sheltered areas. Most often seen in neglected gardens and bushland edges, it smothers understorey plants and even large trees in its quest for light.

Description

The stem is pale and hairy and climbs by twining around a support. Leaves are large and heart-shaped or lobed.

Morning Glory is most easily recognised by its large bluish-purple bell-shaped flowers seen from spring through summer and autumn. On related species, the flowers may be white or pink.

Morning Glory rarely sets fruit in Sydney. Rather it relies on its vigorous growth habits to spread. It is transferred from garden to bushland by the dumping of off-cuts in garden waste.

Noxious Weed Category: 4

Control & Removal Methods

Where there are large areas of Morning Glory (and no other plants you wish to retain) the leaves can be sprayed with glyphosate.

Alternatively, vines can be removed by hand by tracing each stem and teasing out the roots produced at each growth node. Where plants are well established a deep tap root may be present. This must be dug out, or if digging is too difficult, the root and stem can be scraped with a knife (do not sever the stem) and painted with glyphosate.

Vines up trees can be cut and left to die. After it is dead, the vine will quickly rot or you can gently pull vines from trees by working around the tree, taking care not to damage branches.

Keep an eye out for bird nests or ring-tailed possum dreys amongst Morning Glory. Wait until bird nesting season is over before removing Morning Glory or leave the cut vines in place to die slowly allowing ring-tailed possums time to relocate.

Whether you spray or hand weed, any area where Morning Glory has been removed must be monitored monthly as any missed stem or root will reshoot and grow very quickly. You won’t get it first go; perseverance is the key.
