There sure is! It's largely based on attracting certain pollinators at certain times of year, based on their breeding cycles.

Oh thank you! I'm going to have to keep my eyes open next Spring to see what connections I can make. I already know white time is bee time and hummingbirds love the red. Pink is favored by a small yellow butterfly that I've sadly neglected to identify despite seeing them every year. I'm sure I can figure out more! *nature nerd squee*
