Sorry for the delay!! I've been without internet for several days.
Sunglasses Needed is such a great daylily - the color and form make it an amazing standout in the garden. It performs pretty well in my zone5 garden (though truthfully with the snow I doubt the plants frequently see those temps as they're well insulated) and will rebloom up here. The scape height and bud count are lower in the north but that's nearly universal so I don't count it against the plant.
