I did manage to dig up a bunch of plants, mostly natives, to take to the plant swap. There were some black-eyed susans already there, so I picked up a few of those. Most of what I got was actually trade off the plant sale table, plus a couple Little Bluestem from the greenhouse, courtesy of their plant expert. Sea Oats, Side-Oats Gramma, Closed Gentian, Wild Prairie Petunia, and Purple Prairie Clover. I'm also on record for getting some pots of Big Bluestem and/or Prairie Dropseed when those get big enough to plant -- they've just been started so it'll take a few weeks. Some of the plants I got today are tiiiiny so will require extra care and hardening off before they can be planted outside. We'll see how they do. I checked the stuff I planted from Celebration, though, and they all seem to be surviving despite the rough weather.
We went outside for a little while, and saw a fox squirrel stripping bark from a tree. It was cute to see her stuffing her mouth so full of fiber. We think she's building a nest -- there was a partly finished one in a nearby tree that looked to contain more bark shreds than deciduous leaves (usually the preferred material for squirrel nests). The weather was damp and intermittently sprinkling rain, but at least not pouring; the team of tree planters seemed able to complete their project.
All in all, it was a very enjoyable Earth Day. What are you doing for Earth Day?
