Potatis, 'Solanum tuberosum' is ‘potatoes’. The word comes via the English plural form from Spanish patata, originally batata in a Caribbean language, on Haiti. That was the 'sweet potato', however, but the word was later extended to the common potato from Peru. Solanum is probably created from Latin sol, ‘sun’, and tuberosum means ‘with many tubers’.
To the Solanum genus also belong for example tomato and eggplant, and in the large Solanaceae family we also find Chili peppers and tobacco, and several ornamental plants such as petunias and Angel’s trumpets. It seems many solanaceaes are poisonous or at least bitter-tasting.
This bunch doesn’t look very good as you can see - it has been a wet year and snails have been hard on them. We have cultivated this purple variety for many years. We call it ‘Torpane’ because that is where we got it from, but the official name may be ‘Tyska röda’.
