一盆植物英语表达为 "a potted plant."
"Potted" 来自英语单词 "pot"，表示盆、罐或壶。而 "plant" 指植物。所以 "potted plant" 意思就是盆栽植物。
例句：
I bought a potted plant for my office. (我为我的办公室买了一盆盆栽植物。)
She placed a potted plant on the windowsill. (她把一盆盆栽植物放在窗台上。)
Potted plants are a great way to add some greenery to your home. (盆栽植物是给家里增添绿意的好方法。)
