There are 10 Parthenosisus species that are native to North America and Asia.
Household pets, children
Oxalate crystals (raphides), and possibly other compounds may be responsible for the signs of gastroenteritis reported in children eating the leaves or berries. Similar toxicity has been reported in budgerigars fed the leaves.
Parthenocissus are perennial, deciduous, woody vines, with tendrils with terminal pads that enable the creeper to climb on walls, trees and fences. The leaves are palmate, compound with 5 leaflets that are serrate. The leaves turn bright red in the Fall. Small greenish flowers are produced in paniculate cymes. Fruits are blue to black berries with 1-4 seeds.
Boston ivy (P. tricuspidata)is a similar species.
Excessive salivation, and vomiting can be expected
Virginia creeper is of minimal risk to animals, but it is commonly grown in people's gardens and the ripe fruits are attractive to pets and children.
