Autumn Minaret Daylily. Without a doubt, this has to be the tallest daylily that I have ever seen. I am 5'10" and the flowers can be over my head. It is a late season bloomer and I have seen flowers as late as mid October on its 6' scapes, hence the name 'Autumn Minaret.' But the amazing thing about it is that stems are so strong that they don't blow over even in 40 mph wind gusts. The flowers have narrow yellow petals with a soft bronze eye, but its best claim to fame is its height. On good rich soil, I have seen them as tall as 7'. And as with all daylilies, the flowers are edible. A salad garnished with daylily flowers is stunning. Just make sure you don't use any pesticides on your plants if you intend to eat them. Daylily blooms have a slightly peppery lettuce flavor. Eat them in bud or after opening.
