A petition's going around, growth seen around end of year? (10)
I believe the answer is:
poinsettia
'growth seen around end of year?' is the definition.
I can't tell whether this definition defines the answer.
'a petition's going around' is the wordplay.
'going around' indicates anagramming the letters.
'a'+'petitions'='apetitions'
'apetitions' is an anagram of 'POINSETTIA'.
Can you help me to learn more?
(Other definitions for poinsettia that I've seen before include "Shrub often given at Christmas" , "poisonous bush" , "bloom" , "Ornamental house plant" , "Plant with showy bracts, usu. red, pink or white" .)
