I did the same, though it was a long sprout - about 1 or 2 inches. It
appeared happy in a glass dish (hi sides) with dirt and placed by a sunny
window. The dirt was kept damp.
When moved out doors, it started to turn brown. Assuming this indicated
a lack of water, heaps were dosed daily and its still there and growing
too.

I stuck a sprouting tuber in a rised bed and it just died!
