Bizarre name associated with a solitary flower (7)
I believe the answer is:
anemone
'flower' is the definition.
(anemone is a kind of flower)
'bizarre name associated with a solitary' is the wordplay.
'bizarre' indicates an anagram.
'associated with' says to put letters next to each other.
'a solitary' becomes 'one'.
'name' anagrammed gives 'anem'.
'anem'+'one'='ANEMONE'
(Other definitions for anemone that I've seen before include "A flower; mean one (anag.)" , "Kind of buttercup with white or coloured flowers" , "Plant with brightly coloured flowers - found also in sea" , "Woodland plant, eg the windflower" , "Pretty flower or sea animal" .)
