Jerusalem-artichoke
Helianthus tuberosus
Jerusalem artichoke is a vigorous, fast-growing perennial grown primarily for its edible tubers, which are harvested in autumn. Plant in a sunny to partly shaded spot with fertile, well-drained soil and water regularly during the growing season. Be mindful of its spreading habit — it can become difficult to contain, so consider planting in a raised bed or using root barriers.
