Definition

Noun: * Jerusalem artichoke sunflower: A tall perennial plant (Helianthus tuberosus) characterized by hairy stems and leaves. It is widely cultivated for its large, irregularly shaped edible tubers, which are also commonly called Jerusalem artichokes or sunchokes. The plant is a species of sunflower.

Usage

• The term is used specifically to refer to the plant species itself, distinguishing it from the edible tuber it produces.
• It is a compound noun that functions as a single unit to name this particular plant.

Examples

• Noun:

  • We planted a row of Jerusalem artichoke sunflowers at the back of the garden for a natural screen.
  • Unlike the common sunflower cultivated for seeds, the Jerusalem artichoke sunflower is primarily grown for its tubers.

Advanced Usage

Notes on Different Meanings
