Ok, so I am completely and utterly unoriginal. I have no idea where ECF started, but I love looking at other people's pics, so here is mine!
While we do not have blue bonnets here in central New England (growing zone 4-5), we do have False Indigo (Baptisia australis), which I love.
False indigo is a stunner, it attracts butterflies, naturalizes, gets funky-looking seed pods and is a native to the eastern US. What more could a gardener ask for?
