I have a ginger plant and a potato plant, both growing untended in my yard! I have neither the time, talent, nor energy (nor the tolerance of heat, humidity, and mosquitos) to do much gardening, so I've been randomly planting things in areas where they might have a shot at growing. I'm very happy to see at least two of them thriving!
I can now add these to the pecans, fledgling hickories, inland sea oats, and the fig tree my great-grandmother planted.
