They are related but not identical. Sphagnum moss refers to the living plant. Peat moss is the partially decomposed remains of sphagnum and other plants that have accumulated over centuries in waterlogged conditions (peat bogs).
Gardeners use it primarily for its excellent ability to retain moisture and improve soil structure, and because it creates a slightly acidic environment favoured by many plants.
