I've only had Sandra Elizabeth since May of 2021 and am already impressed with this daylily. The scapes hold the pretty, yellow blooms well above the foliage and branching is such that each bloom has room to shine. I've not seen rust on it. It bloomed in mid August in 2021, but in 2022 and 2023, it bloomed from the second week of July through at least the first week of August. It is registered as very late and this one definitely starts much later than many of my other daylilies. August Flame and Sandra Elizabeth bloom about the same time in my zone 6b garden.
I did not measure the scapes, but I think it gets taller than the registered height of 28 inches.
August 12, 2021 - three months after planting in my garden.
July 20, 2023 - two years later - it has multiplied very well!
July 10, 2023 - branching is awesome and bud count is maybe between 15-20, but I don't have a true count of either.
July 31, 2023 - no rebloom, no polys, and no fancy frills with this one. But it is a beautiful yellow with bouquets of blooms in the late garden.
