Feed a Bee is offering free garden seed packs. Each seed packet contains about 200 wildflower seeds and you can request up to 20 free packets!
The seeds included are a mix of wildflowers, including partridge pea, black-eyed Susan and purple coneflower, that will grow well in most regions. I'm hoping they sprinkle in a few of those Money Trees my Dad was always talking about! I still contend he should have bought one instead of working so much.
I believe the earlier free wildflower seeds offer is still active too!
