Do you have room under your shaded outdoor eating area where you could plant the shell ginger? Mine are planted on the north side of the house and they bloom nicely. All they need is some bright light.
Have you ever seen the Pipevine Swallowtail butterfly in your yard? The Pipevine Swallowtail is mostly black and it lays its eggs on the Pipevine. I planted the smaller variety of pipevine two years ago, Aristolochia trilobata, but I have not seen the Pipevine Swallowtail as yet.
