Bunium bulbocastanum

Earth-nut is a perennial herb known for its edible tubers and delicate flowers.

Also known as: Earth-nut

Bunium bulbocastanum, commonly known as Earth-nut, is a perennial herb native to Europe and parts of Asia. It typically grows to a height of 30 to 60 cm, forming a clump of finely dissected, feathery leaves that are reminiscent of carrot foliage. The plant produces small, white to pale pink flowers in umbels, which bloom from late spring to early summer, followed by the development of tuberous roots that are edible and have a nutty flavor. These tubers serve as a food source for various wildlife, contributing to the plant’s ecological role in its native habitats.

Earth-nut is often found in grasslands, meadows, and open woodlands, thriving in well-drained soils. It has adapted to a range of soil types, from sandy to loamy, and is known for its ability to withstand periods of drought once established. Historically, the tubers have been used as a food source by humans, particularly in times of scarcity, and they can be consumed raw or cooked. The plant’s ability to produce edible tubers and its resilience to varying environmental conditions make it a valuable species both ecologically and for human use.
