About Great pignut
Bunium bulbocastanum, commonly known as greater pignut or earth chestnut, is a perennial herbaceous plant from the Apiaceae family, prized for its edible tubers. Its delicate white umbelliferous flowers and carrot-like foliage make it attractive in herb gardens or naturalized landscapes. It is ideal for kitchen gardens or as part of an edible plant garden, providing seasonal interest with its blooms and underground harvest.

Care tips
It prefers full sun to partial shade and well-drained soils, preferably sandy or loamy. Watering should be moderate, allowing the soil to dry out slightly between waterings, especially during the active growing period. A substrate rich in organic matter will promote good tuber development. A common mistake is waterlogging, which can lead to tuber rot; ensure excellent drainage.
