NAPRA Ireland risk assessed
Vigorous deciduous vine; woody climber with a light brown stem up to 20m long; palmate leaves divided into 5 leaflets, dull green and hairy on underside; tendrils with adhesive tips for climbing; difficult to identify in winter (Booy et al., 2015). Can be confused with a number of different native and non-native species including P. inserta (nn), P. tricuspidata (nn), Hedera helix (ivy native) and various Clematis spp (both nn & native) (Booy et al., 2015).
May overgrow and compete with native plants. Host to a plant pathogen, Xylella fastidiosa, in its native range (Hopkins & Alderz, 1988). Due to rarity in Britain (Preston et al., 2004) and Ireland (Reynolds, 2002) there are no documented studies of its impact outside its native range.
Inland unvegetated or sparsely vegetated habitats; Regularly or recently cultivated agricultural, horticultural or domestic habitat; Constructed, industrial or other artificial habitats
Pathway and vector description
Widely sold as a garden plant along with P. inserta and P. tricuspidata, for which it can be confused.
Mechanism of impact
Grown in gardens from where it may spread it is most common in hedgerows and waste ground (Reynolds, 2002).
P. tricuspidata, P. inserta
Occasional - Rare, mainly found in the south of the country though this may be an artefact of recording effort.
Native of North America (Preston et al., 2004).
