Wisteria Color of Blossoms

Question

Have just moved into house with a garden. There’s a beautiful and well-established wisteria vine, espaliered against a wooden wall.  However, the blossoms are not the usual purple or lavender. Instead, they are a dirty white color. Can I change this color by adding something to the soil, as can be done with hydrangea that is pink rather than deep blue?

Answer 1

Unfortunately, there is no way to change the color of the wisteria. Lack of color is normally caused by poor soil nutrition. Have your soil tested and amend it accordingly.
