what tropical plants [or look a likes] or hardy for z6a cincinnati ? i am near the river [3 blocks].
Jeff, none that I know of. They would all need to be kept above 40 degrees - do you have a warm area to store them over the winter?
There are all kinds of interesting plants for up north, I used to live in OH. Not sure if you have shade or sun, what size plants you want, but there's... Wisteria, Dicentra (bleeding hearts,) Pieris, Baptisia, Brunnera, Alchemilla, Polygonatum, Thalictrum, Heuchera, ferns, staghorn sumac, bottlebrush buckeye, Hostas, Hisbiscus syriacus (rose of Sharon,) ginger, not to mention all of the bulbs that can be stored dormant in a basement... elephant ear, Cannas, Gladiolus, Dahlia, Caladium.
Musa bananas are known to overwinter where you are with a little extra care, this guy's doing it. I lived in central OH and had Mirabilis jalapa against the basement wall on the west side, which survived for years and the tuber was moved to AL and is still doing great. A friend a few blocks away had perennial Cannas around her brick patio, for about 15 years until I moved down here.
Jeff, thought of this post when I saw this.
