There are a few hibiscus that can be called picotee. This term usually refers to a flower showing a darker edge around a lighter colored base color. There are a lot of hibiscus that have an outer edge that is lighter than the base color but this style is not usually considered picotee.
We've offered a few varieties that are picotee style - Allure, Blueberry Smoothie, Double Trouble, Miss Congeniality, Magic Carpet Ride, and Torch Song come to mind. Scroll through the Gallery pages to see these with the darker edge.
http://www.hiddenvalleynaturearts.com/cbcultivarsWith hibiscus, many times the outer edge is a prominent feature when the flower is freshly opened, but the color will change or fade once exposed to sunlight and high temperatures and in those cases the flower would no longer show the picotee look. Not sure whether that would eliminate them from the picotee class or not, but several of those listed have that changing quality to the edge.
One cv that does not lose the edge color is Hoosiers. It has white petals surrounded by a distinct and vivid red color. Very pretty flower. Not a very good bush so not found very often in hibiscus collections. My plants of it have hung in there for quite a few years now which tells me that the bush does have longevity if not good growth habit.
Another picotee that Dale Dubin hybridized is Whipt Butta. That one is also white or pale yellow but this time with a darker yellow edge. Dale was interested in developing more picotees before he quit hybridizing to attend to his medical interests.
I'm sure there are other examples out there, but flowers with darker edges around lighter base petals is one of the more rare types of hibiscus flowers.
Below is a good example of Hoosiers.
