Thanks for the information guys.

Ummm...Swamper..thanks for the kind offer but I am not a wildflower kind of gal. I already purchased 5 ginger plants for one side of the garden; I only have to choose the plants for the other side.

But you are kind. :) I am putting an oncidium sphacelatum on one of the trunks of the palm trees if that helps. :)
