Wisteria macrostachya ‘Blue Moon’

Best grown in slightly acidic, humusy, moderately fertile, medium moisture, well-drained soils in full sun. Full sun is needed for best flowering. Can be somewhat invasive (rampant growth plus rooting surface runners). This vine needs space and a sturdy support structure on which to grow. It can be slow to establish. Although this vine may produce flowers by the second or third year after planting, it may take longer. Pruning for this wisteria should be kept to a minimum (e.g., pruning back tips after bloom or in winter). Improper pruning may overly stimulate vegetative growth at the expense of flowers.  (Courtesy of Missouri Botanical Gardens Plant Finder)
