  • Posted by ILPARW (southeast Pennsylvania - Zone 6b) on Feb 4, 2018 6:45 PM concerning plant:
    The Japanese Wisteria is occasionally found in Eastern and Midwestern landscapes in the US. It is a powerful, fast-growing woody vine (liana) that twines clockwise upon things. It blooms before the foliage emerges, with violet or blue-violet large grape-like clusters on old wood in April-early May. It is a very rampant vine that will kill trees if growing upon them and can break trellises or fences that are not strong, and it will grab anything. In USDA Zone 5 it often does not bloom because of late frosts. When it gets old it often does not bloom much, so gardeners often will give it super-phosphate and root prune to get it to bloom better. It has escaped cultivation in some areas. especially down South, and is invasive and a nuisance. There is a very similar Chinese species that should be considered a variety as the two can hybridize. The Chinese is supposed to leaf out a little later and climb counter-clockwise. They both can ground sucker and become quite a mess.
