I added Blueberry Breakfast in 2021, but even so it did flower its first season in the gardens. I'll have to do a much more thorough inspection in 2022 to truly evaluate it, but on short acquaintance ... I kept it to the front of the border as it was not a very tall daylily (as mentioned by others).
It bloomed reasonably well for a first year in the garden, I expect much more increase in fullness of the plant (multiplying) and quantity of flowers, but have to say that it gives a great first impression.
The colour really is blueberry - looks like the fruit ... sometimes that waxy blue outer skin of the blueberry, and at other times, that raspberry-purple blue of the inner fruit. I have nothing else in the gardens with this particular colour - I would keep it for that alone, even if it had no other assets. But it bloomed well and I am looking forward to seeing it become well-established here.
