One may be "bottomless" at brunch (6)

I believe the answer is:

mimosa

(Other definitions for mimosa that I've seen before include "Shrub - I'm Amos (anag)" , "One growing sensitive" , "Plant genus popularly extended to the Acacia" , "Type of acacia tree" , "Variety of acacia" .)

I've seen this clue in the Universal.
