Climbing plant known for its lilac flowers (8)

I believe the answer is:

wisteria

(Other definitions for wisteria that I've seen before include "Climbing lilac-flowered shrub" , "A flower, I swear it" , "Large climbing shrub, often attached to house" , "Vine with pendulous clusters of flowers" , "Climber" .)

I've seen this clue in The Guardian.
