Information about  Araujia sericifera from other sources

[Wikipedia] Distribution: The plant is native to South America: Peru mainly,: These plants grow in wastelands with trees and hedges, in forests and in rocky places or cliffs. They prefer sunny or partially shady places, at an altitude of 0 to 1,800 metres (0 to 5,906 ft) above sea level. The fast-growing vines can cover a tree canopy in two or three years, competing with the tree for light, water, and nutrients. They damage trees by this competition and by twining so tightly around their branches that it girdles them.[9] (contributed by Mary Ann Machi)

[www.aphis.usda.gov] Impact potential described: Impact Potential Araujia sericifera has dense foliage that smothers native shrubs and trees and prevents the regeneration of native species in natural ecosystems. Additionally, the heavy weight of fruiting vines can break tree branches (Weber, 2003) and floral secretions of A. sericifera can kill native insect pollinators (EPPO, 2008; Weedbusters, 2011). Araujia sericifera can quickly become a dominant plant in urban settings (ARC, 2007). Some gardeners need to control it in their backyards (Dave's Garden, 2011). In California, A. sericifera grows in citrus orchards, where the vines compete with citrus trees for water, nutrients, and light; kill individual tree branches by girdling; reduce fruit yields; and interfere with pruning practices (Dave's Garden, 2011).
