Grey and White Limestone

This rock is ideal for creating mini rocky landscapes populated by mosses, pinguicula, and plants that typically grow on rock faces. It doesn't have true holes but has many well-defined crevices where a minimal amount of pinguicula soil can be placed at the base.
This rock becomes very dark when wet, almost black with white streaks, and creates a strong contrast with the green color of mosses and pinguicula.
