Thank you for planting my favorite plants(bromeliads, heliconias). I was wondering if you would plant anthiriums in your garden and pond areas too.
I also have another suggestion for your bog area and around the pools and ponds, various carnivorous plants. They are very unique and mind blowing with their abilities. Many of them bloom flowers too.
These are various the blooms of the anthurium plant. These plants will bloom continously in your garden because of your tropical environment. As you can see there are various colors.
Here are some of the carnivorous plants:
The Nepenthes- This is the Very well known and sought after-Nepenthes bicalcarata-Your son and daughter may appreciate too. Here is a link to a grower of Nepenthes and you can select which one you like the best.

Here are some of the many carnivorous plants and their are pure aquatic species too like the bladderwort(They help with fish and insect population control, they get sucked into the traps similar to catfish sucking in prey)

Also the Alocasia Amazonica plant with the dark leaves and white/mint green veins would be great too. It has a burgandy color on the back. They will get huge in your area. They will grow more in a round bush form and get taller too.
Here is photo of a smaller plant front and back pics:
Here is a link with more varieties of the Alocasia plant even giant forms.
