What else are you seeing outside? We'd love to hear about it.
The goldenrods in our yard are beautiful right now. Open sunny areas should be full of their yellow glow. Be sure to look closely for all the cool little critters that are attracted to the bright flowers.
Ragweed is also blooming: the scourge of the fall allergy sufferers of Washington, DC. Unlike goldenrod, which attracts all kinds of pollinating insects, ragweed relies on the wind to spread its pollen. I just wish it wouldn't spread it into my nose. This is one thing that the rain makes better: those airborne pollen particles get sogged down and don't fly around as much.
Black Walnuts are starting to fall from trees all over the DC metro area. They're a hard nut to crack, which could explain why they sell for $14 a pound. Pick up a few for yourself and see what all the fuss is about.
Pawpaws are the largest fruit native to the DC area. In groves of mature trees, you can find them littering the ground, ready for eating. Of course, you'll have to beat the raccoons and opossums to them.
Find enough and you can make pawpaw-walnut cookies.
Chicken of the woods is a hard-to-mistake and hard-to-match mushroom. We found several with all the rain in August...keep an eye out in September as well.
Goldfinches live in the DC area year-round, but we seem to see more of them at this time of year as they come to feed on the seedheads in our flower garden. They're such a pretty little bird.
Spicebush is a common understory shrub in our local forests. In the early spring, it's got pretty yellow flowers. Over the course of the summer, the pollinated flowers transformed into little green berries. And soon, they will be turning bright red. Also, keep an eye out for spicebush swallowtail caterpillars, who you can sometimes found curled up inside a leaf. In my opinion, they're one of the best-looking caterpillars around!
