My eremurus robustus has pink pollen; I noticed this because the honeybees that are on it all day while it is in flower have pink socks (the pollen they gather on their legs I think of them as stuffing in their socks).
It’s hard to get a pic because the plant is so tall and in the center of a bed, and the bees wave me off if I get too close, but today I finally got a pic that shows it.
Another very cool thing? The flowers are a great illustration of the whorls that nature makes, the flowers open in a rising spiral from the base.
