Morphology
The phrase transparently signals a plant associated with Ireland — a B1 learner who knows 'Irish' and 'moss' will likely infer it is some kind of Irish plant or moss. However, the established sense refers to a red/seaweed (not true moss) used as a culinary thickener and dietary supplement, which is not derivable from the literal constituents, so the full meaning is not predictable.
Etymology
Irish moss probably comes from where it grows and how it looks: people in Ireland found a dark, moss-like plant on the rocks and called it Irish moss. People used this 'seaweed' to 'thicken' soups and desserts, so today the name means the edible seaweed used as a natural 'thickener'.
