The information on local (indigenous) potatoes is often confusing, primarily because so much of it is still anecdotal; although this may reflect the limited access to articles that I have in Burundi.
Above is a picture of one of the two varieties, the second – Solenostemon rotundifolius has beautiful leaves:
A herb with prostrate or ascending habit and a succulent stem reaching up to 15-30 cm in length, forming tubers in clusters around the base of the stem. The tubers are small and dark-brown.
USES The tubers are used in the same way as potatoes.
GROWING PERIOD Annual herb, tubers are ready for harvest after 150-200 days from planting.
