Supporting Data: Qsn # Question Answer 101 Is the species highly domesticated? n Source(s) Notes [Hybrid cultivars are naturalized and invasive. No evidence of domestication] "Exotic Wisteria species are highly favoured for their horticultural qualities and have been cultivated in North America since the early 1800s. This study determines the identity, genetic diversity and hybrid status of 25 Asian Wisteria cultivars using plastid, mitochondrial and nuclear DNA data. Fifteen (60%) hybrid cultivars were identified. All of the ͚Wisteria sinensis͛cultivars Trusty, J. L., Lockaby, B. G., Zipperer, W. C., & Goertzen, L. sampled are hybrids with W. floribunda. Although W. sinensis and W. R. (2008). Horticulture, hybrid cultivars and exotic plant floribunda are recognized invasive species in the southeastern USA, invasion: a case study of Wisteria (Fabaceae). Botanical the relationships of horticultural cultivars to naturalized plants was Journal of the Linnean Society, 158(4), 593-601 previously unknown. Haplotype analysis of nuclear data identifies four haplotypes shared between cultivated stock and naturalized populations in the southeastern USA. In addition, US invasive haplotypes are present in New Zealand-derived cultivars although, to date, naturalized Wisteria has not been documented in New Zealand. Finally, these data are used to make recommendations to horticulturalists of select species cultivars which may be less likely to invade US landscapes." 102 Has the species become naturalized where grown?
