Irish moss is not really a moss. It's a flowering plant, Sagina
subulata. While it will take some foot traffic, it really will not take
the constant traffic of a frequently used path. Actually, it will do
better between stepping stones than as something on which to step.

Irish moss requires conditions quite different from true moss. It
requires good soil, good drainage, and full or part sun.

Very similar to Sagina subulata in both appearance and culture is
Aremaria verna, which is also called Irish moss. Both are sometimes
called Scotch moss. Both are hardy to around 5F but will also thrive in
mild-winter climates; however, neither will survive the heat and low
humidity of a desert.

Any sugestions of something that would work for what I described?
