Selaginella diffusa

This Selaginella is a nice greenish burgundy and will drape over landscape features in a very attractive way.  It is easy to keep contained and grows somewhat fast once established, but annual trimmings are enough to keep it nicely sculpted in my experience.  It forms large flat trailing pieces that are somewhat angular looking.  It is a larger species in thickness, but it stays low to the ground (under 3?).

For size reference, the tank is approximately 22″ wide.  I have found it grows very well even in standing water.
