Right before all the leaves fall to the ground, the tulip really is quite magnificent. I'm not sure if this show attracts pollinators, as the info on line is not clear. It seems tulips may self pollinate or the wind blows the pollen around. Anybody know? It seems this lovely show must have a purpose. One thing is sure, the pollinator, if there is one must, is diurnal as the tulips close up at night.
