It’s dark green and has a stalk attached. Anyone know what it might be?’ This was a question submitted by a gardener to an online discussion forum (Gardener’s World, 2014), and it is not unusual for gardeners to ask why their potato plants have flowers or berries on them (Fig. 1)
The potato (Solanum tuberosum) originates from Central and South America, and the first plants brought to Europe in the 16th century were of the andigena subspecies (Solanum tuberosum ssp. andigena) from the Andean Altiplano of west-central South America.As such, they were adapted to conditions in which day length did not change much through the year and, when grown in the higher latitudes of Europe, would not tuberize until the autumn, when day length had reduced to ~12 h.This made the potato difficult to cultivate in higher latitudes, by the early 19th century it was already a staple in countries such as Ireland where the mild climate was conducive
