I picked this up the last time I was in Oklahoma. It's one of my favorite rocks in my flower beds. I got it on E785 Road. Take the Welling Road, cross the creek and go left.
A friend of mine gave me some ginger roots a few years ago. I planted them (of course) and they came up and made real nice plants. I thought I had lost them this year because they were real late coming up after the winter. So now they are beginning to bloom.
I really don't know what they will look like when they are fully bloomed.
