Morphology

sphagnum + moss

The phrase is a straightforward noun–noun compound naming a type of moss (a moss of the genus Sphagnum); if a learner knows 'sphagnum' and 'moss' the meaning is directly derivable. This compositional botanical naming pattern is regular and cross-linguistically common, so it will be clear to B1 learners who know the constituents.

Etymology

Sphagnum moss refers to a pale, sponge-like plant: sphagnum, a kind of moss, that soaks up and holds a lot of water. That's why gardeners use sphagnum moss to keep soil moist and why it slowly breaks down into wet 'peat' in bogs.
