Solanum palustre is a wild, non-tuber-forming relative of the potato from central and southern Chile and adjacent Argentina, mainly studied for disease and frost resistance. It is not a common garden plant, so care is best matched to a cool-temperate, moist, frost-tolerant perennial.
Solanum palustre (syn. Solanum brevidens) is a species of wild potato in the family Solanaceae. It is native to central and southern Chile, and Neuquén and Río Negro Provinces of Argentina. Although it does not bear tubers, it is still being extensively studied for its resistance to Potato virus Y, Potato leafroll virus, early blight, late blight, common scab, bacterial soft rot, and frost.
Solaunum palustre is part of the Petota lineage, which is a subclade of the Potato clade (which also includes the Tomato clade). An updated phylogenetic analysis from 2025 employing genomic information confirmed this to be one of the three species belonging to the Etuberosum subclade, alongside Solanum etuberosum and Solanum fernandezianum.
