Description

Helianthi is a close relative of the famous Jerusalem artichoke (Helianthus tuberosus) and can be used in exactly the same way. However, the tubers even surpass topinambour in terms of nutrient content and (in our opinion) of taste! It grows almost
everywhere. The tubers have a long tradition as a staple food in the Americas. Harvesting takes place only when needed, so that the tubers can grow continuously. In Europe, Helianthi seed is quite rare, as the seeds do not fully mature in temperate climates.
