emergenceEmergence of shoots typically occurs after the last spring frost and when soil temperatures consistently reach 7°C or higher.
floweringFlowering is initiated by shortening day lengths, typically in late summer to early autumn.
fruitingFruiting (seed set) follows flowering, though the primary reproductive effort is tuber formation.
senescenceFoliage dies back with the first hard autumn frost.
harvestTubers are typically harvested after the first hard frost has killed the tops, which improves their flavor, and can continue through winter until the ground freezes solid.
dormancyTubers enter dormancy in the soil after the foliage dies back due to frost.
