。
She picked flowers.
Literal
She [topic-は] flowers [object-を] picked.
About as compact as a Japanese sentence gets: topic, object, verb. 摘む ('to pluck, pick, nip off with the fingertips') is the specific verb for picking flowers, leaves, herbs, or anything you take with a small finger motion — distinct from 採る ('gather, collect') or 取る ('take, grab'). The kanji 摘 (with 扌 'hand' radical) literally pictures a hand picking. The bare past 摘んだ has a clean, literary ring that fits descriptive prose like a children's-book scene or a poem fragment.
