Blue

I'm not sure why the sight of this blue mulch in a tree pit in Park Slope was such a jarring sight to me. It can't possibly be because blue isn't a natural color in the plant world, as evidenced by some of the fantastic blue flowers I witnessed at Brooklyn Botanic this year.






























Tweedia caerulea, just one of the fantastic plants chosen by Caleb for Brooklyn Botanic's centennial annual border


















The magic of Anne's Centaurea and foxgloves in spring.






























Salvia reptans in the Rose Arc, one of Sarah's late summer bloomers.

Blue: pretty amazing in nature, not so much in the tree pit.
