Almost instantly--bees! Honey bees love the purple pollen of pink poppies, so much so that several became bogged down by the heft of their pollen baskets and had to be tipped out of the blooms. Did they fly straight back to the hive, unload, and return?
Nope. Like big-eyed kids at Halloween with loot bags overflowing, they flew directly, sort of heavily, to the next poppy. Pink poppy purple pollen is seriously addictive.
