She had orrises, peculiar plants (13)

I believe the answer is:

horseradishes

'plants' is the definition.
(horseradish is a kind of plant)

'she had orrises peculiar' is the wordplay.
'peculiar' is an anagram indicator.
'she'+'had'+'orrises'='shehadorrises'
'shehadorrises' anagrammed gives 'HORSERADISHES'.

I've seen this clue in The Telegraph.
