Warm woman, Erica? (7)
I believe the answer is:
heather
'erica?' is the definition.
(plant genus including heather)
'warm woman' is the wordplay.
'warm' becomes 'heat'.
'woman' becomes 'her' (**).
'heat'+'her'='HEATHER'
(Other definitions for heather that I've seen before include "Girl's name - ling" , "Small purple evergreen plant growing on hills" , "Evergreen shrub" , "Girl" , "Moorland flora" .)
