Austinl01,
There's a large plastic pond liner under the pebbles. I decided to make it pondless because of my curious 2 and 4 year old. The liner is deep enough to hold fish, so I plan on converting it to a pond later once my kids are old enough to know the difference between a pond and swimming pool

. I've been looking for water plants which I can submerge into the rocks and water.
Besides the bananas, here's a list of the different plants; different types of dwarf and tall canna, giant bird of paradise, elephant ears, pineapple lily, ornamental grasses, rose hibiscus, passion fruit along the fence, pink guava, yellow angle trumpet, lemon guava, strawberry guava
