Growing Purple Sweet Potatoes

 Here's something a bit different!  I love Purple Sweet Potatoes!  Having left a few on a windowsill in the kitchen I noticed a couple of weeks ago that they had started to put out shoots.  I decided to see if I could propagate them, so with the aid of my new garden assistant Daisy, I cut off the top of the sweet potato and planted the shoots in some potting compost.


 Lo and behold in just a couple of weeks of warmth, water and sunshine the two tops had filled this pot with roots.  Sweet potatoes are not related to normal potatoes in any way and they grow quite differently.  Actually they are related to the columbine or bindweed family.  They propagate through these vegetative slips which put out roots when buried in the soil.
 So carefully I separated the individual slips and tried to get some roots on each cutting.
 The potato itself does not put out any roots, just the green shoots so I had to separate them quite carefully.  It is fairly late in the season to be doing this, I really should have planted slips around May, but let's see what happens in my South facing walled garden.  I have planted some slips in containers and in a large pot, so if at the end of the season they are not quite ready... I can bring a pot indoors and give it some extra heat and light to encourage it.
So fingers crossed the slugs don't get all of them!  I'll keep you posted!

I wish you luck! I tried that last year (slips planted in May etc), but they didn't produce much of a crop. I didn't think it worth repeating, but since you have a nice sunny spot for yours you'll probably have more success.

That is interesting. I lived in America for a while and got used to eating sweet potatoes over there. I'd never eaten them before. Now I've noticed lots of them in Sainsbury's and buy them, mainly to roast with the joint on Sundays. Delicious aren't they.
I love that you're trying to grow them and will be watching attentively to see how you're getting on with it. Good luck!
