Second-generation cold-hardy mashua tubers, selected from plants that thrived through harsh Welsh mountain winters at altitude in the Brecon Beacons.
These aren’t just imported tubers – they represent proven adaptation to UK conditions. Each tuber carries the genetic memory of surviving north-facing slopes, heavy frost, and marginal soils. If they thrive here, they’ll flourish in most UK gardens.
