picking herbs and wildflowers
Especially associated with early spring, when young edible plants and wildflowers are gathered.
When spring comes, we go out as a family to pick wild herbs and flowers.
We made kusa-mochi with the mugwort we picked while gathering wild plants.
Compound of 草 (kusa, 'grass, herb') and 摘み (tsumi, 'picking', the noun form of 摘む tsumu). The reading is a straightforward kun'yomi combination.
