Plant such as wattle (6)
I believe the answer is:
acacia
'plant such as wattle' is the definition.
(I've seen this before)
This is all the clue.
(Other definitions for acacia that I've seen before include "Tree or shrub with yellow or white flowers" , "Spiny shrub with clusters of yellow or white flowers" , "Shrub of warm climates" , "Flowering tree or shrub" , "Spiny tree or shrub" .)
