That's a great job you did with your first year tropical garden. It's really beautiful. I love those ee, I'm going to have to try some next year. I'm new to tropicals and so far have banana(zebrian & super dwardf cavendish) ginger, mandevilla and cannas. I love them all.

Thank you so much for I.D.ing those for me. I do like to know what the proper names for plants are.

Now, If I could just remember to mark them so I don't lose track of them in the winter.

Now you need some cold hardy palms like Sabal Minor, Windmill Palms and Needle Palms to feel like you are in the tropics.
