Potato (Solanum tuberosum) with underground stems and young tubers
The perennating organs of the Potato (Solanum tuberosum) are underground tubers, which are swollen stems acting as food stores. Originally from the lower Andes in South America, this plant has been exploited in Europe as a food source since the 15th Century, owing to the high starch content and good keeping qualities of the tubers.
This image shows part of a plant dug up to expose underground stems with swollen tips – the immature tubers. Part of the main root system of the plant can also be seen.
The largest tuber is approximately 2 cm across.
