Aruncus Aruncus is a genus of clump forming herbaceous perennial plants in the family Rosaceae. Botanical opinion of the number of species differs, with from one to four species accepted. They are closely related to the genera "Filipendula" and "Spiraea", and are native to mountainous damp woodland in temperate regions of the Northern Hemisphere. Creamy white plumes of flowers are produced above veined and toothed leaflets.

It is closely related to the genera "Ardisia" and "Geissanthus", and various species have been transferred between the three genera. All three were formerly placed in the family Myrsinaceae, which is now treated as a subfamily (Myrsinoideae) of the Primulaceae.
