Lia had this odd flower (6)

I believe the answer is:

dahlia

(Other definitions for dahlia that I've seen before include "Showy flower from Mexico" , "Flower genus" , "Showy garden flower" , "Aid Hal (anag) - flower with showy heads" , "Lia had this flower, strangely" .)

I've seen this clue in The Irish Times.
