Native Grape Vine
Vitis spp.
This is a native species that supports local ecosystems. Please do not remove this plant.
Description
These native vines have shaggy bark and forked tendrils. They provide food and habitat for birds and insects - leave them in place.
Where you'll find it
Stream sides and floodplain woods, looping up into the canopy without blanketing the tree it uses.
Forest edges and hedgerows, often in the same tangle as porcelain berry.
Recognisable in winter with no leaves at all: shaggy bark peeling in loose strips, and forked tendrils.
How to identify
The leaf
Heart-shaped with a deep notch at the base.
Colour and texture: Mid-green above, hairy or woolly underneath. Run a thumb across the back. Porcelain berry is smooth and slightly shiny underneath.
Seedheads & fruit
Fruit August–October.
Dark purple-black grapes hanging in drooping clusters.
Why it matters: Hanging and single-coloured, against porcelain berry’s upright clusters of speckled turquoise and lilac. Food for birds and foxes. Leave it.
River grape is a native vine that feeds birds and pollinators. Porcelain berry is an aggressive invasive that looks a lot like it. Because we remove porcelain berry on sight, make sure a vine fails these checks before you cut it.
River Grape
Vitis riparia
Native: keep
Heart-shaped, deep notch at the base, fuzzy underneath.
Porcelain Berry
Ampelopsis brevipedunculata
Invasive: remove
Speckled turquoise and lilac berries. Nothing native fruits like this.
Bark
River Grape
Shaggy: mature vines peel in loose, papery strips. Young stems are smooth and reddish-brown, but they never show white dots.

Porcelain Berry
Never peels. Young stems are smooth with raised white dots (lenticels); older bark grows dull and ridged but stays intact, with no shaggy strips.

Leaf underside
River Grape
Hairy or woolly underneath. Run your thumb across the back of a leaf.
River grape leaves: heart-shaped with a fuzzy underside.
Porcelain Berry
Smooth and hairless underneath, often slightly shiny.
Stem pith (snap test)

Snap a pencil-thick stem: the pith inside is tan to brown.
Porcelain Berry
Snap a pencil-thick stem: the pith inside is bright white.
Tendrils
River Grape
Tendrils are forked (branched).
Porcelain Berry
Tendrils are unforked.
Growth habit
River Grape
Climbs loosely into the canopy without blanketing its host tree.

When in doubt, leave the plant and ask a site lead before removing it.
