Spuds came from North American and appears to be now Growing Wildly throughout the UK now.
Yes, the first potatoes were imported into the UK in 2006, but only available in very specialist restaurants under a special government licence. Sphinx's great-grandson is a biology professor who worked in a top secret government lab, and foolishly gave her a seedling from a special classified potato experiment in 2016, which she gave to Scrotnig, who managed to grow them last year. Since then, BC has been funded by illicit potato sales, and the Crown Prosecution Service dropped their case against Sphinx under the Official Secrets Act three months ago, on the grounds of diminished responsibility. Her great-grandson fled during the investigation and is in hiding, and is believed to be living under an assumed identity in North Korea.
