Will aggressively and quickly scrabble to over two storeys high completely smothering and enveloping any house or tree.

When in flower has very showy creamy-white trusses of flowers. (Here climbing amidst leaves of Common Polypody).

Leaves typically Bindweed in shape. Leaf stems can be reddish.

A flower stalk emerges from the axils of short reddish brown 'spikes' or more correctly pedicles.

From up close the flower trusses are seen to consist of a mixture of three-winged tepals similar to those on Docks and five-petalled flowers, both whitish.

The tepals are reddish to greenish white bulges within three white wings. Even the flowers have frilly white wings on them. It seems likely that the 3-winged tepals open up to become three-petalled flowers (with wings) plus two extra petals that have come from somewhere.

The flowers have five petals, three of which have a greenish stripe down the centre and arranged in an equilateral triange; plus two slightly shorter white petals without stripes sitting between two of the larger petals, making an bi-symmetric arrangement.

The three plus two petal arrangement on display. Five stamens carry cream-coloured pollen at the tips. The tripled inner is lime-greenish.

Tepals, clustered in groups, typically terminate the flowering stems.

The ovate/triangular leaves are wavy-edged and often bronzed when young.

Older leaves are dark green. Lower stems woody.


Easily confused with : Flower [a plant of similar name]

Not to be confused with : Russian Knapweed, Russian Mustard, Russian Cinquefoil, Russian Lettuce, Russian Comfrey, Grape Vine or Chilean Potato-vine [plants with similar names]

Some similarities to : Black Bindweed but that grows very much shorter, is an annual rather than a perennial, and has much smaller flowers with many more tepals than flowers.

Uniquely identifiable characteristics

Distinguishing Feature :

When grown in gardens, this plant can be very troublesome, rampantly growing so tall as to cover the house and block out the windows or cause damage. It can easily climb up to two storeys high.

A member of the Dock and Knotweed Family it exhibits characteristics of both: it has tepals like docks and it has sheaths on the stems at every node like Knotgrasses. But the leaves are more characteristic of Bindweeds and Knotweeds than Dock. Indeed, it shares the same Genus name Fallopia with Japanese Knotweed, Giant Knotweed, Black Bindweed, and Copse-Bindweed. The flower trusses, from afar, resemble those of Japanese Knotweed and some other members of the same Genus.

Habitat includes gardens, but is often naturalised in hedges, in scrub and on cliffs. Unlike its cousin Japanese Knotweed it does not spread rampantly or un-controllably around the countryside, merely grows rampantly upwards or outwards as one plant. It is known as the Mile a Minute Vine with good reason, for it can grow a metre in a week. Random outbreaks are unusual, if it is found 'in the wild' it is probably a throw-out from a garden.

The fruit, in reality an achene, is about 2mm long and shiny black. It is native to the far East such as western China and Tibet.

It is said by some that some cultivated 'varieties' differ from the wild, but Mr. Clive Stace finds no evidence for this.
