We live in a rather rural area of Western Washington State. Our nearest neighbors are invisible from a human line of site with most land owned in blocks of 5-100 acres. Lots of time surrounds us. And while I can see what's flowering and growing in and around our pastures, that's about it. So when I see the bees coming back this time of year with different color pollens gathered, other than the orange from our own dandelion lawn/garden, I have no idea what they are bringing back. It's moot to them, though I am curious George about stuff like that. Are there any accurate pollen color charts that might be either state or region specific for the US available online?
