5 repeat flowering wisterias

Wisteria frutescens 'Amethyst Falls'

The Wisteria frutescens ‘Amethyst Falls’ is part of the less well-known hybrids of American Wisteria, compared to Chinese and Japanese Wisterias. Interesting for its more moderate growth, reaching about 4 to 5 m in height at ripeness, its flowering is very quick: it can bloom as early as the first or second year after planting. Its clusters of flowers are denser and more compact than those of Chinese Wisterias and slightly less fragrant. Wisterias derived from Wisteria frutescens or American Wisteria have the ability to produce repeat flowering: they bloom abundantly for the first time in spring, in May-June, among the foliage, and then again in successive waves from late summer to autumn.

‘Amethyst Falls’ stands out with its beautiful amethyst purple flowers. Easier to integrate into small spaces, it has a compact growth habit and differs from the botanical species by having longer and slightly fragrant flower clusters. Its stems naturally twist around supports in a counter-clockwise direction. This variety is propagated from cuttings, unlike most other Wisterias which are often grafted.

Wisteria sinensis 'Flore Pleno'

The Wisteria sinensis ‘Flore Pleno’ is, as its name suggests, a double-flowered form of Chinese Wisteria. Its wonderful and long clusters, measuring 30 to 40 cm in length, come in a gradient of mauve: from pale mauve, almost white, to intense and rich mauve, nearly violet. They emit a powerful fragrance with honeyed notes. The floribundity of this vigorous variety is enhanced, and while it blooms profusely for the first time in spring, in April-May, before the foliage appears, on almost naked stems, it then flowers again more lightly during the summer, among its light green leaves.

The stems of ‘Flore Pleno’ reach 9 to 10 m in length when mature. They twist around supports spontaneously in a counter-clockwise direction, a characteristic feature of Chinese Wisteria, as is its significant growth which requires a very sturdy support. The growth of new shoots, soft and villous, is very rapid, reaching several metres in a single season in cool soil. The young leaves, bronze in colour, appear at the end of flowering and then take on a light green hue. In autumn, they turn golden yellow before falling.

Wisteria frutescens var. macrostachya 'Blue Moon'

The Wisteria frutescens var. macrostachya ‘Blue Moon’ is derived from the American Wisteria, Wisteria frutescens, but it descends from a subspecies, macrostachya, found in a more restricted geographical area, ranging from Missouri to Kentucky. The Wisterias of this subspecies, Wisteria frutescens var. macrostachya, are commonly known as Kentucky Wisterias. They bloom in late spring, in May-June, while the foliage is already present. Being repeat flowering, they can easily and sporadically bloom again up to twice during the summer, with their clusters always nestled among the dark green foliage.

‘Blue Moon’, compact and highly floriferous, produces clusters of lavender-blue flowers, speckled with yellow-green. They measure 20 to 35 cm in length, are dense and fragrant. This variety reaches about 4 m in height at maturity, and its new shoots grow approximately 80 cm in a season under good conditions. Flowering occurs 3 to 4 years after planting, but it is a very beautiful plant, perfectly suited for training as a tree, given its small size, to showcase it beautifully.
