Big Size Jerusalem Artichoke, Also Known As Sunchokes, Sunroot, or Jerusalem Artichokes, Individual Tubers For Planting.
Sunchoke tubers can be sown in the garden as early as two to three weeks prior to the typical springtime last frost date. The soil should be warmed to 50°F (10°C) before planting. Sunchokes can be sown in the dead of winter in areas with warm winters. It takes 110 to 150 days for sunchokes to be ready for harvest.
The sunchoke is a tough perennial that reaches heights of 5 to 10 feet. Small yellow blooms measuring 2 to 3 inches (5-7cm) across are atop the plant's rough-textured leaves, which are 4 to 8 inches (10-20 cm) long. Sunchokes can withstand a strong winter if they are covered with soil or mulch. Tubers expand and split quickly, but root barriers can stop them.
The plant is not related to the artichoke, despite the name Jerusalem artichoke being a misnomer; the sunchoke's flavor may be evocative of the artichoke. The name of the plant, which means "turning to the sun," is likely taken from the Italian word for sunflower, girasole, which is not a native of Jerusalem.
Grow sunchokes in direct sunlight. The sunchoke may grow practically anywhere, but it favors loose, well-drained soil.
spacing and planting. Sunchoke tubers should be planted 12 to 18 inches apart, 2 to 6 inches deep. Rows should be 36 inches apart.
