Kusamochi, literally "grass mochi", also known as yomogi mochi, is a Japanese sweet. It is considered a seasonal dish for spring. It is made from mochi and leaf of yomogi (Artemisia princeps), or more traditionally from the Gnaphalium affine. It may also be filled with red bean paste.
Kusa mochi may also be used to make a kind of daifuku called yomogi daifuku.
