Yep.. hell strips... Overused in the landscape because they are bombproof here. Where I used to live, the city parks/maintenance folks would cut them to the ground around the end of February so all the growth would be fresh.. They can look a little shabby if not groomed. I've got the variegated form that is a little on the shy side of blooming. Used to be called Moraea. Taxonomists like to keep us horticulturalists on our toes by changing names every so often.
