Our cars are all covered with pollen but I don't know where it's from or if it's even anything they can use. The only thing we have here that I can think of is the arborvitae and I don't know if that's a pollen that they can use.
That pollen that gets all over everything and makes people sneeze is almost always from wind pollenated plants, around here the spring pollen explosion is the pines. The bees
can use that pollen, but it's not very high in nutrition and they will typically collected something else if it's available.
