They get 5-6 hours of sun. This is always the amount they got. On the left of Nairobi Dawn there is Spanish Glow, and it grows and blooms normally.
I had other two diploids that was going really down and was almost dead, Siloam Merle Kent and Little Show Stopper. They had like empty and floppy roots, so I saved the remainings and planted in pots. They are alive now but not in my garden anymore. SMK never flowered much, but LSS was a very big clump, then something happened. Stella De Oro is flowering a lot less than the first two years.
Stella is in clay soil, but the others are in a bed with different soil.
