Awkward youth plans to give flower (10)
I believe the answer is:
polyanthus
'flower' is the definition.
(I know that polyanthus is a type of Primula)
'awkward youth plans' is the wordplay.
'awkward' indicates an anagram.
'youth'+'plans'='youthplans'
'youthplans' is an anagram of 'POLYANTHUS'.
'to give' acts as a link.
(Other definitions for polyanthus that I've seen before include "Bloomer" , "plant" .)
