American kidney bean 'Amethyst Falls'

Wisteria frutescens 'Amethyst Falls' | Also known as: American wisteria 'Amethyst Falls' | Rating: 4 votes | Print / Pdf

The lesser known of the Wisteria climbing shrubs, Wisteria frutescens is nonetheless one of the most impressive. Its bright green foliage marks it out as a very attractive option, with glossy, pinnate leaves ensuring a light freshness prevails at least until autumn. Commonly called the American Wisteria, it flowers quite late in the season, with its highly fragrant lilac or purple blossoms emerging in summer. It is also more discreet, with its pendulous floral panicles hiding behind thick foliage. But it can bloom in its first year, thus negating the patience usually needed for Wisteria. It thrives in moist but well-drained, and humus-rich soil. Pruning in spring is recommended.
