peony
芍 refers specifically to the peony plant, a flowering herb. The meaning is narrow and botanical, without broader abstract extensions.
芍 combines the grass radical 艹 with 勺, which likely contributes a phonetic element. The character is used specifically for the peony plant.
The grass radical 艹 sits above 勺, like a ladle-shaped plant. Picture a peony blossom cupped like a ladle among the grass.
For シャク, imagine a peony in a shack: shack -> シャク, and the flower grows right outside the small wooden building.
