Moss can be a divisive subject among gardeners, but Erica Nordstrom's new book, titled "Moss - Discover. Gather. Grow. From forest to garden: a guide to the hidden world of moss" might help to persuade some of the non-believers. The book manages to combine botanical detail, a visit to some astonishing moss gardens in Japan, the US and the UK and some practical projects for making your own moss gardens.
Here in Switzerland, the two webpages that will get you started are www.bryolich.ch for information on the Swiss Association of Bryology and Lichenology and www.bryophytes.ch for identification pictures and help on collecting samples and which mosses are protected and shouldn't be touched
