Plant with a tiger tooth variety (4)

I believe the answer is:

aloe

(Other definitions for aloe that I've seen before include "Genus of bitter herbs" , "Succulent plant (4) 5532" , ". . . . vera, soothing plant" , "Plant source of purgative drug" , "Fleshy-leaved plant" .)

I've seen this clue in the LA Times.
