What kind of bee is this?

We have a few wasps and bees buzzing around, it comes with the territory when you have as many flowers as we do. However, most of them are of a smaller variety. We have a broccoli plant growing in our herb garden, right outside our back door, and Kevin noticed this honking big bee. It didn't appear particularly aggressive. Bigger doesn't always mean meaner. With all the bee problems in the world, we're always grateful to see them here.
