Plant — drainage (anag) (8)

I believe the answer is:

gardenia

(Other definitions for gardenia that I've seen before include "Bad drainage produces a fragrant flower" , "Fragrant tree or shrub" , "Shrub such as the Cape jasmine" , "A reading (anag.)" , "Evergreen" .)

I've seen this clue in The Guardian.
