I heart my riccia lawn.
Newbie here - I love the photos of this stuff too. I have Pellia on drift wood, an I have the riccia floating...and I haven't figured out how to contain the stuff. Do I just plop it on a rock and cover it with a hair net and wait?
And I have two different types that I am not sure - one looks like the "Y" shaped riccia that I am seeing here on this thread, and the other is very dark green and more translucent and large wavy type "leaves" with no roots...is it also riccia?
Thanks for putting up with my ignorance on this.
