Fragrant wisteria.
With an air of old-fashioned charm and romantic permanence, wisteria transforms any structure into something magical. Dense clusters of lilac-blue flowers drape from its branches, filling the air with an intoxicating perfume. Grow against walls, strong pergolas, over archways or even in large containers on your patio.
It's a vigorous climber once established but can be condensed into a small garden by careful pruning.
Harmful if eaten.
