Parthenocissus quinquefolia, known as Virginia creeper, Victoria creeper, five-leaved ivy, or five-finger, is a species of flowering vine in the grape family, Vitaceae.It is native to eastern and central North America, from southeastern Canada and the eastern United States west to Manitoba and Utah, and south to eastern Mexico and Guatemala.
Virginia creeper and poison ivy very often grow together, even on the same tree. Even those who do not get an allergic reaction to poison ivy may be allergic to the oxalate crystals in Virginia creeper sap. Western poison oak (Toxicodendron diversilobum) leaflets also grow in threes on the end of a stem, but each leaflet is shaped somewhat like ...
Colchicine poisoning has been compared to arsenic poisoning; symptoms typically start two to five hours after a toxic dose has been ingested but may take up to 24 hours to appear, and include burning in the mouth and throat, fever, vomiting, diarrhea, abdominal pain, and kidney failure. Onset of multiple-system organ failure may occur within 24 ...
It has a more restrained growth than the other Virginia creepers. [2] The large palmate leaves consist of five to nine oval leaflets, each up to 12 cm (5 in) long, with strong white veining. The leaves colour to a brilliant red in autumn before falling. Clusters of inconspicuous flowers in summer may be followed by black fruits. [3] [4]
It is widespread in the eastern half of the United States, [1] and commonly noticed defoliating grapes, especially of the Virginia creeper (Parthenocissus quinquefolia). The western grapeleaf skeletonizer ( Harrisina metallica ) is very similar to and slightly larger than H. americana, but their distributions are different.
Parthenocissus inserta is closely related to and commonly confused with Parthenocissus quinquefolia (Virginia creeper). [5] They differ in their means of climbing, with the tendrils twining around plant stems in P. inserta lacking the round, adhesive discs found on the tendril tips of P. quinquefolia, though the ends may be club-shaped when inserted into a crevice.

A new critter is creeping into the United States' waters. The invasive Australian redclaw crayfish was recently spotted in Southern Texas, roughly 8,000 miles away from its home. The freshwater ...
Angular leaf scorch of grapevines has been observed on 18 species of grapevines Vitis, on interspecific hybrids of Vitis, and on Virginia creeper Parthenocissus quiniquefolia. [2] An early symptom of angular leaf scorch of grapevines is the presence of faint chlorotic lesions near major veins on the leaf surface. [ 3 ]
