State flower of New Mexico (5)
I believe the answer is:
yucca
'state flower of new mexico' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for yucca that I've seen before include "House plant with spiky flowers" , "Common indoor plant" , "Plant of the Agavaceae family" , "tapioca!" , "Ornamental plant" .)
