Description
Sunchoke, also called Jerusalem artichoke, is a tall native sunflower relative with an edible surprise below ground. The plants bring late-season yellow blooms, then form tubers that can be harvested after flowering or left to expand the patch.
Why Grow It
- Perennial edible crop for gardeners who like resilient, returning harvests.
