Bloomer that can lead to tears (5)

I believe the answer is:
aster
'bloomer' is the definition.
(aster is a kind of flowering plant)
'can lead to tears' is the wordplay.
'tears' anagrams to 'ASTER'.
Though, I am unsure how this is indicated.
'that' acts as a link.
Can you help me to learn more?
(Other definitions for aster that I've seen before include "Plant of Michaelmas daisy family" , "Tears about bright flower" , "Large daisy" , "Flower of the daisy family - rates (anag)" , "Plant like a Michaelmas daisy" .)
