Buzzing in the Garden

When I returned from a recent Easter adventure in Ohio, my first stop - before unpacking and all that unfun stuff - was the garden. While inspecting the Bachelor's Button, I noticed a wasp on a bloom. The wasp circled and stayed for hours. As long as it doesn't try to build a nest in my eaves or under the deck, it's welcome to the flower nectar.

This is one of the first pollinators I've seen this season. I wonder what it thinks of the English Daisies I planted a few containers down. In about a month my lavender, chamomile, and zinnias will be in full bloom. Besides the Bachelor's Button & English Daisies I have a few other flowers in bloom:

What's your favorite bloom? Anything in your garden drive the pollinators wild?
