Flourishing iris loving fresh earth (6,4)

I believe the answer is:

virgin soil

'fresh earth' is the definition.
(soil that has not been cultivated)

'flourishing iris loving' is the wordplay.
'flourishing' indicates anagramming the letters (letters grow or flourish differently).
'iris'+'loving'='irisloving'
'irisloving' anagrammed gives 'VIRGIN SOIL'.

(Another definition for virgin soil that I've seen is " Land never previously tilled".)

I've seen this clue in The Times.
