Hi Kathleen,
Sphagnum bogs are my favorite US habitat as well (Maybe we shouldn't admit this on a geophyte forum). This particular alpine bog surrounds a little pond, and several acres of it are covered with giant Puyas whose branched flower stalks form a little forest more than ten feet tall. Every time I visit, the place is misty, and the network of flower stalks just sort of fades off into the white fog.
