Plants of the iris family (8)
I believe the answer is:
gladioli
'plants of the iris family' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for gladioli that I've seen before include "I laid log in the flowers" , "Plant with brightly coloured, funnel-shaped flowers" , "Did the Iliad log out these flowers?" , "bloomers!" , "Garden plants of the iris family" .)
