Wisteria sinensis Ruderal Vine-Shrubland
Translated Name: Chinese Wisteria Ruderal Vine-Shrubland
Common Name: Ruderal Chinese Wisteria Vineland
Unique Identifier: CEGL008568
Classification Approach: International Vegetation Classification (IVC)
Summary: This vine-dominated vegetation is dominated by Wisteria sinensis or Wisteria floribunda, or most often hybrids of the two fast-growing vines native to Asia. The community is most commonly seen in fragmented landscapes near old homesteads and other areas. The oldest colonies may consist of Wisteria sinensis or Wisteria floribunda and little else since the wisteria slowly overtops and kills all other plants It has the potential to occur in most southeastern states.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: Eight populations were sampled in Alabama, Florida, Georgia, North Carolina, and South Caroline. Analyses of nuclear and chloroplast genomes amplified segments revealed that 24 of 25 collections were identified as hybrids of Wisteria floribunda and Wisteria sinensis. Plant traits are not indicative of this. From this research there is indication that this long introduced and bred group of plants are well-hybridized, which imparts hybrid vigor. Still, there is certainly some value to photograph representative plants using traditional keys for identification as well as stating the case for hybridization (Trusty et al. 2007).

Vegetation

Vegetation Summary: The vegetation is dominated by Wisteria sinensis or Wisteria floribunda, or most often hybrids of the two exotic vines native to Asia (Trusty et al. 2007). Wisteria sinensis and Wisteria floribunda were introduced as ornamental vines in the southern United States in the 19th century. These are not nearly as invasive as Pueraria montana var. lobata, but in forests that have been disturbed by windstorm or other severe disturbances, these vines can colonize the canopy and spread to adjacent trees. In areas like this, where control has not taken place, they can colonize more than 1 hectare. All existing vegetation is eventually choked out, leaving mounds of dying or dead trees overtopped by layers of Wisteria sinensis or Wisteria floribunda, or most often hybrids of the two exotic vines.

Environmental Setting

Wetland Indicator: N
Environmental Summary: This association occurs in a wide variety of habitats, but tends to occur in areas that were formerly second-growth pine or tuliptree woodlands. Since this species invades by overtopping trees, this community tends to occur in highly fragmented areas that are near old homesteads or other past human habitations where wisteria persists. This community is rare across the landscape at this point, but there is the potential for it to occupy more land as fragmentation continues to occur.


Dynamic Processes

Dynamics: This association chokes out existing vegetation.
