Can You Change Wisteria Flower Color Like Hydrangeas? No.

Wisteria flower color is genetic, not soil-pH dependent. A “lavender” plant that blooms white was mislabeled. Hydrangea color change (with aluminum sulfate) does not work for wisteria.

What to Do

Enjoy the white blooms—they’re beautiful.
If you need lavender, buy a plant in bloom to verify color.
