Perennial · Zingiberaceae

Common culinary ginger is grown from pieces of living rhizome rather than seed and makes lush tropical foliage before swelling edible underground stems. In zones 5-8 it is best treated as a warm-season container crop that starts early indoors and appreciates partial shade in high summer.

Harvest

For green ginger, harvest once the plant is leafy and rhizomes are plump but pale and tender; for mature ginger, wait until foliage yellows late in the season.

Expected Yield 0.5–2 lbs/plant

Storage 30 days — Refrigerate unpeeled rhizomes dry in a bag, or freeze pieces for long-term use.
