The flowers of Sweet Pepperbush (Clethra alnifolia) are highly prized by many insects. This bank of Pepperbush grows wild next to our old house site -- I'd guess it's at least 100' wide long and 20' wide. Some of it is 10' high. It smells wonderful!
Insects throng to the sweet flowers in droves. There are four carpenters bees in this picture alone.
