Pretty pictures in the idea ... is not it? A rock, I think TUFF, with some niches where host Pinguicol and different varieties (they are carnivorous plants ).
Perhaps difficult to find a suitable rock in the garden, but now I start looking, because I realize in the garden, in a bright area but with little direct sunlight.
A beautiful saucer top, bottom or just a vessel to contain more water, and the period of leave may also take the automatic irrigation water, in fact the problems Pinguicole NOT have to be watered with water "normal" tap , and not demineralized.

The idea tickles me ... then I could order from the plants the Extreme-Plants , Holland, from which I have already bought 6 plants at good prices, even some I have sent 2 because they were small plants.
