Had trouble with each rising flower (6)
I believe the answer is:
dahlia
'flower' is the definition.
(dahlia is a kind of flower)
'had trouble with each rising' is the wordplay.
'trouble' indicates an anagram.
'with each rising' becomes 'lia' (I am not sure about this - if you are sure you should believe this answer much more).
'had' with letters rearranged gives 'dah'.
'dah'+'lia'='DAHLIA'
Can you help me to learn more?
(Other definitions for dahlia that I've seen before include "Lia had this strange flower" , "In bed, root" , "Showy, big-headed autumn flower" , "Strangely, Ali had this flower" , "Showy flower from Mexico" .)
