Marimo, Japanese Moss Ball

A year ago I came across a mention of Marimo somewhere on the net. I had forgotten about them until a couple of weeks ago I found myself in an aquarium store and saw some in a fish tank. Since this was a serious kind of aquarium shop they were labeled "Japanese moss balls" but I recognized it right away as a "Marimo." Being one of those suckers born every minute I had to have one if only for the plant geek points. Lately I've been sort of uninspired with collection of indoor plants and have had the strangest urge to grow mosses and ferns. Which is partly responsible for the lack of updates here. I don't know why but lately but plants that are little more than boring green mounds have seemed like something I want to grow.
