I'm in zone 4 and have always loved the patterned daylilies. Back in the 90's they were hard to find, but now with the popularity are a bit easier. Stenciled Impressions and Mystical Rainbow are a few that have been here a very long time and do very well. A few others that are reliable and grow in zone 4 for me are....
Huckleberry Candy, lightly patterned, some days more,some less, good plant.
Screen Pattern, great pattern, lacks branching/budcount this far north, but a gorgeous pattern.
Jerry Hyatt, one of my all time favorite daylilies, will always be here.
In Taffeta Patterns, another favorite, the pattern changes more than with Jerry Hyatt.
Man in the Maze, a changing pattern and form.
Labyrinth, this one has been here since introduction and has done really well.
Shattered Illusions, dormant with a consistent pattern, looks the same every day.
There's a Place, love this one, cool lavender/orchid with a bluish watermark.
Marseilles Watercolor, registered as evergreen but has been here and growing happy 6 years now.
