RE-grow sweet potato from single branch

I love sweet potato leaves. Just wash then broil it, drain well, add some dried fish, or just add some salt. You can buy it in Asian Market.

Eating the leaves and re-planting the branch is my habit. Need a small jar (glass is preferred) with water, put it there and change water every 2 days. Let's see~~~

Day 1

Day 3

After three days, the white stems come out.... Hope I can harvest sth later haha
