One of the most beautiful trees we have in the Spring is the Red Buckeye, Aesculus pavia. In the fall it produces seed pods which you can gather and plant to grow more red buckeye trees. Last year the squirrels beat me to it but not this year! Here's a short video of me gathering and planting red buckeye seeds.
