When Should A Wisteria Flower. Jun 01 2021 Japanese wisteria flowers bloom on new growth so you will need to prune twice a year to manage both size and to keep branches close to the main structure to allow for enjoyment of the profuse blossoms. Wisteria sinensis grows in an anticlockwise direction and Wisteria floribunda clockwise.
Therefore it commonly blooms before the plant actually leafs out. To avoid disappointment buy your wisteria in flower or choose a named cultivar. Gardeners are often devastated when their wisteria fails to bloom the first season after planting.
Thats why it seems counterintuitive to say prune it now.
Jan 06 2021 If you notice beautiful purple blooms prior to foliage growth then you probably have a Chinese wisteria. This is a variety of a native vine known as Kentucky wisteria which is not as aggressive as Chinese wisteria. Feb 16 2019 Wisteria is kind of weird for a woody vine because it blooms on both old and new growth. Be patient a newly planted wisteria may take several years to mature before it begins flowering.
