More about Amethyst Falls Wisteria...

Have you always loved the incredible show of bloom and fragrance of a Wisteria vine in full bloom, but didn't want to spend the rest of your life trying to control its growth? Your worries are over! Introducing our own homegrown 'Amethyst Falls', a native Wisteria. Though Amethyst Falls will grow 20 to 30 feet in length, it is much less invasive and easier to manage than are its Asian cousins, which can run wild!

While the Asian types of wisteria may take 10 years or more to begin flowering, Amethyst Falls begins flowering at one year of age. Flowering occurs on new growth and is about two weeks later than that of the Asian types, so late-winter frosts seldom affect flowering. What's more, new shoots produced after the spring bloom will produce a second flush of blooms in the summer!

Considered by some to be a dwarf wisteria, Amethyst Falls has smaller leaves and flowers than the Asian types. Flowers are fragrant, lavender-blue and borne in 2- to 4-inch-long racemes that cascade from the foliage like a waterfall. 

Deer and drought tolerance are other outstanding attributes that earned Amethyst Falls Wisteria a Gold Medal award in 2006. 

Uses

It’s a perfect choice for pergolas, trellises or fences. It can also be trained to grow as a small, free-standing tree.

Culture & Care

Because this vine is a native, it is widely adaptable to various soil types and thrives in a wide range of pH (4.5-7). We recommend a well-drained soil. Is happy in full sun or part shade however flowering will be diminished in heavy shade.

Prune Amethyst Falls Wisteria in late winter, if necessary, to shape the plant and remove undesirable growth. Then trim lightly again after the first flush of bloom to encourage branching and more repeat blooms. A late-winter application of a complete fertilizer, such as 16-4-8, should be sufficient for the year. Grows in USDA Zones 5-9.
