Plant in shade Amy claims I cultivated (10,5)
I believe the answer is:
michaelmas daisy
'plant' is the definition.
(Michaelmas daisy is an example)
'shade amy claims i cultivated' is the wordplay.
'cultivated' indicates anagramming the letters.
'shade'+'amy'+'claims'+'i'='shadeamyclaimsi'
'shadeamyclaimsi' is an anagram of 'MICHAELMAS DAISY'.
'in' acts as a link.
(Other definitions for michaelmas daisy that I've seen before include "plant" , "Autumnal flower" , "Bloomer" , "Variety of aster" .)
