The Porcupine potato has a woody basal stem structure (caudex) from which new vine-like growth arises, with angled stems that are strong smelling. It is grown for the unusual caudex, often as potted indoor plants.
Harvest the seeds when the fruit is mature and over ripe.
Sow seeds in early summer. Cover with a sowing medium not deeper than 4-5 cm. Use sandy loam with very well-rotted compost. Plant in a sunny location.
Can be grown in containers, using free draining potting mix.
Provide a lot of bright light, can take some direct sun. It is possible to place the pots outdoors in summer and move indoors in colder climates for winter.
