Irish Moss has been growing along the side of our house for as long as I can remember (we moved into our newly built house in May 1997).

I love it! It's so soft to the touch! Maybe that's why the Chickadees love to gather some of it and add it to the bottom of the birdhouses I hang, so that their eggs and the baby Chickadee birds will have a soft, smooth, and comfortable nest!

I've been growing these for several years and after terrific spring and early summer growth, always have to deal with decline in mid to late summer through autumn. In different full sun locations the centers tended to die out. The first time I divided these I noticed the mesh sleeve the starters were grown out (six packs) from hadn't deteriorated and thought that might be the problem. After division, a similar die back occurred the following year. This year I'll try a moist shaded location for some of those that I have left.

I have attempted to successfully keep this plant over winter three times, both in a pot and in the ground. Seems not to be hardy here in my zone 5 garden.
Still a beautiful plant, so I use it as an annual. Great in miniature gardens and as an accent in pots.
