Plant Profile
Tiger NutCyperus esculentus
Tiger nut is an unusual sedge prized for its nutty-sweet root tubers. In Central Europe, it is mostly cultivated as an annual, as it requires significant warmth to reach its full potential. The plants form dense, grass-like clumps that are ideal for container gardening on sunny balconies.
