Environment Tuberosum alpinus needs moderate, dry conditions. An overabundance of moisture is fatal, so during rainfall, shelter is sought in small caves which line the rocky slopes. Some of these caves contain hot springs, which protect the organism from sub-zero temperatures and blizzards in Winter. In damp conditions, the Alpine Potato is invaded by Pythium ultimum, and becomes moribund, unable to run from predators. Pythium ultimum causes successive greening, purpling, blackening, bloating, and, eventually, death. Extreme dampness occasions invasion by Phytophthora infestans, leading to Sticky Rot, which starts at the extremities and moves inexorably inwards, leading slowly but irreversibly to, eventually, death. |
