Unlike Tripleurospermum inodorum, Tripleurospermum maritimum is a native plant according to New Flora of the British Isles Edition 3 by Clive Stace. The leaves are very similar to Tripleurospermum inodorum except that they are thicker sometimes almost succulent otherwise it looks very like Tripleurospermum inodorum.

Tripleurospermum maritimum sounds like a plant which should be found only at the coast but much of it is recorded inland as well. It is found almost everywhere except on the high ground and as much in the far north as in the Channel Islands and Scillies. It is common on the outer islands including Shetland, St Kilda and North Rona. In Ireland is is common along the whole coastline but there is not so much recorded inland.
