Tropicals & Tender Perennials: Suggestions for tropical bed under my new 12' coconut ?, 1 by JUNGLEGAL

I just had this 12' cocos nucifera installed yesterday. The bed isn't that big at about 10' x 7'. It gets full afternoon sun although I imagine it will be a bit dappled now that the cocos is planted.

I'm asking for suggestions for the under plantings because it takes me forever to visualize my gardens and I don't want this to be a big dirt pit until a lightbulb finally goes off. It's the perfect time for suggestions as the next month is full of spring gardening sales. Thanks in advance.
