And for those who read the frog in the water gauge thread, here are two frog plants. The first is a typical bromeliad. Those formed like this make a perfect place for frogs. Some even lay their eggs in them as they hold moisture in the middle. The smaller plant is
Catopsis, one of only two carnivorous bromeliads. The waxy coating comes off easily, so the bug who wanted a drink from the middle can't get out, and becomes lunch. But tree frogs can live in them, so the plant can take nutrients from the frog's waste products as well. In my greenhouse, a tree frog picked a carnivorous bromeliad to make it's home over the other bromeliads.
