Growing and Maintenance Tips:


Wisteria will do well in an average to moist, well-drained soil in full sun or part shade. Pruning should be done soon after flowering, to ensure bud set for next season's flowers. In the summer months, continual pruning of the new shoots will help maintain a tidy size and appearance. Wisteria needs a sturdy support structure to allow for their vigorous growth habit.

Additional Notes about Japanese Wisteria:


Differences between Wisteria:

Floribunda: 13-19 leaflets on each leaf, stems twirl clockwise, hairy calyx, and the flowers are 1.5-2 cm long.

Sinensis: 7-13 leaflets on each leaf, stems twirl counter-clockwise, slightly hairy calyx, and the flowers are 2-2.5 cm long.

Macrostachya: less agressive/invasive than both. Almost native to Southern Ontario.
