Grow Darn You

  I've been reading a lot recently about growing sweet potatoes 

 I don't want a crop of them. 

 They are supposed to grow, like an avocado pip, in a glass of water and turn into a house plant 

This is what it's supposed to look like after only a couple of weeks

The reality... 

After a month.... 

Growth? 

Zilch, diddly squat, nothingness 

I've googled.  

'Choose a sweet potato with multiple eyes 

All you need is warm water, a glass jar and sunlight' 

They say

'Suspend your sweet potato in a glass of water by poking it with toothpicks' 

They say

'Make sure it's submerged. 

Put it in a sunny window

Refresh the water every few days

Watch as it grows over the next 2 to 3 weeks' 

They say

I did all that. Plenty of sunlight.  I waited. I changed the water

My daughter Elli has done the same

Zilch there as well

Any ideas? 

I suppose I should buy another sweet potato

We get red and white varities

I'll try a white one
