Jerusalem artichoke is the sunflower that went underground and invented fart jokes. Tubers are inulin-rich — great for diabetics on paper, chaotic for dinner parties if portions are naive. It spreads from overlooked tuber bits; treat it like bamboo's polite cousin that still invades if you ignore boundaries. subtropical and tropical Americas grows it fine; harvest in cool months for firmer texture. ☀️💧 Sun and Water Requirements: - Full sun for tall stems and heavy tuber set. - Average to rich soil; steady moisture during growth, drier at harvest if soil allows. - Confine to beds or barrels if you fear eternal volunteers. ✂️ Methods to Propagate: - Tubers: replant golf-ball-sized pieces in spring after last frost. - Crowns: moving clumps resets spread when neighbors complain.
