I had used this photo in another post but it can apply here too.
The plants are Dwarf varieties..
Small Bordelons in the rear are not dwarfs but they can be kept hobbled.
My plants are grown for landscape foliage only..If choose to attempt to flower these I would increase container size and fertilizer regiment.
Knee high Little Prince...sides
Waist high Truly Tiny...middle
Chest high Bordelon.....rear
This is an average size in my zone 5/6.....in your tropical zone they will be somewhat larger.....say 2-4x.
These plants are cute and look great in a weathered vase shaped Italian terra-cotta pot
