Wisteria ‘Burford’

Description

If there is one plant that can stop you in your tracks in late spring, it is a Wisteria in full flower — and ‘Amethyst’ is one of the most beautiful of them all. Long, cascading racemes of rich violet-blue blooms, flushed with deep red-purple at the base, pour from the stems in May in a display that is nothing short of breathtaking. The fragrance is powerful and sweet, carrying across the garden on warm air, and the bees find it before almost anything else.

This is a plant with real presence. Vigorous, generous, and only getting better with age — give it a strong pergola, a sunny wall, or a sturdy arch and watch it transform the space completely over the years.

Wisteria rewards patience. The first few years are about establishment and training — but once it finds its rhythm, the flowering display builds season by season into something truly spectacular.

Caragh Garden Notebook

‘Amethyst’ is a classic Chinese Wisteria with one of the richest flower colours available — that deep violet-blue with its distinctive red flush is something quite special in the late spring garden, and the fragrance is the kind that stays with you.

It grows vigorously — up to 7–8m — and its stems twine anticlockwise as they climb, which is worth knowing when you are training it onto a support in the early years. Guide the main stems in the direction they want to go and they will get on with it happily.

After the flowers fade, attractive bean-like seed pods form along the stems and carry interest through the summer months.

Caragh tip — the one that matters: Prune twice a year without fail. In summer, cut the long new shoots back to five or six leaves. In winter, cut those same shoots back again to two or three buds. It sounds involved, but once you get into the rhythm it takes very little time — and it is the single thing that makes the difference between a plant that flowers generously and one that simply grows.
