Leapt the wrong way - that's a bit of a bloomer
I believe the answer is:
petal
'a bit of a bloomer' is the definition.
(I've seen this before)
'leapt the wrong way' is the wordplay.
'the wrong way' indicates anagramming the letters (I've seen this in other clues).
'leapt' with letters rearranged gives 'PETAL'.
'that's' is the link.
(Other definitions for petal that I've seen before include "Floral segment" , "Part of flag" , "Bit of blooming" , "Floral feature" , "Small seal set in a ring" .)
