A wee pest's destroyed pretty plants (5,4)

I believe the answer is:

sweet peas

'pretty plants' is the definition.
(type of plant)

'a wee pest's destroyed' is the wordplay.
'destroyed' indicates an anagram.
'a'+'wee'+'pests'='aweepests'
'aweepests' is an anagram of 'SWEET PEAS'.

(Another definition for sweet peas that I've seen is " Plants".)

I've seen this clue in The Times.
