Plants Incas over cultivated (9)

I believe the answer is:

veronicas

'plants' is the definition.
The answer is an example.

'incas over cultivated' is the wordplay.
'cultivated' indicates an anagram.
'incas'+'over'='incasover'
'incasover' with letters rearranged gives 'VERONICAS'.

I've seen this clue in The Independent.
