Landscaping with Potted Vetiver

Vetiver makes an interesting landscape specimen plant.
Here (above) is one outside my window along with a kangaroo, a spineless Prickly Pear and a Dragon Fruit vine.
I also grow Vetiver in pots filled with water. I use Azolla, a water fern, on the water surface to keep mosquitoes  from breeding. The floating Azolla also adds texture  and a rich green colour to the landscaping.
I'm using these pots of water growing Vetiver  with Azolla as a companion to  shade  and cool down the opening to my work area. The Vetiver blocks radiated heat while the breezes pass through its leaves to enter the house.
That's the ambience theory anyway.
