Evergreen version of pea, encased in pot (8,5)

I believe the answer is:

japanese cedar

'evergreen' is the definition.

'version of pea encased in pot' is the wordplay.
'version of' is an anagram indicator.
'in' indicates putting letters inside.
'pot' becomes 'jar'.
'pea'+'encased'='peaencased'
'peaencased' anagrammed gives 'apaneseced'.
'apaneseced' going into 'jar' is 'JAPANESE CEDAR'.

I've seen this clue in The Guardian.
