I got Yellow Ducky in 2011 and it increases quickly. It is one of the hardest daylilies I have to get a good picture of.
The color is so bright it gets washed out in the sunlight and taking a picture on a cloudy day leaves it looking dull and dark. But it is very pretty in person and I love the teeth on it. I've never seen rust on it.
6/13/21 - it blooms about 4 weeks and even though it is registered as Mid-late, it blooms mostly in June in my zone 6b garden.
H. 'It Is Finished' is in the background.
Branching is good with between 3-5 way and between 15-18 buds.
It is pod and pollen fertile because I had a bunch of seeds from it. However, I eventually threw them away for lack of space to plant them.
