At least 4 or 5 years ago, I was given a couple of pots with seedlings in them.
I was told they were Malabar Chestnut trees.
I planted them in the yard and forgot about them except for checking on them maybe once or twice a year.
A few months ago I saw some large white Mimosa looking flowers laying on the ground under the trees.
Today, I saw a green seed pod up on the end of a branch.
Then, I looked under the tree and saw a brown open pod laying on the ground with over a dozen seeds in it.
I gathered the seeds[nuts] up and am drying them to experimentally eat them.
My experience with raw wild nuts [hazel nuts (filberts)] is that they need to be dried thoroughly before eating or they will be very bitter.
I expect these to be similar.
I can find nothing about them in a search here.
Anyone familiar with them?
