From the genus name.

trifolium (plural trifoliums or trifolia)

(botany) Any of the genus Trifolium of clovers and trefoils.
- 1867, Wilson Flagg, “The Early Wild Flowers”, in The Magazine of Horticulture, Botany, and All Useful Discoveries, page 155:
  The larger species (Panax quinquefolium) is rather coarse and ordinary in its appearance; the flowers are very nearly like those of the trifolia, but grow in an irregular and elongated cluster.
- 2012, Douglas M. Considine, Foods and Food Production Encyclopedia, page 441:
  The majority of the trifoliums are native to Europe and Asia. Only comparatively few of the trifoliums native to the United States are of food production significance.

From tria (“three”) + folium (“a leaf”), a calque of Ancient Greek τρίφυλλον (tríphullon).
