Another joyous event in addition to spring peepers is when I see wild bloodroot. It started blooming a few days ago on a steep, wet bank between the road and a farmer's hayfield. I don't know how many years I drove past that spot before I noticed the flowers. They close up at night and when it's overcast.
Forsythia is blooming extravagantly right now as well as the traditional spring daffodils. Are there any wildflowers in your neighborhood that bloom this early?
