I am late to the sweet potato party. Looks like you are having fun.
With only a small garden I grow mine in large containers - like the kind landscapers discard after planting huge trees.
At harvest time I have a few neighborhood kids come over and stick their hands into the soil and feel around for the sweet potatoes.
It's good fun even if the kids get a bit dirty.
My daughter peels and cuts up the sweet potatoes and steams them. She does the same with an equal number of white potatoes, then mashes them together as a topping for Shepherd's Pie. Another way we like them is quartered the long way, brush with olive oil, sprinkle with coarse Kosher salt and toss them on the grill for a while. Yum.
There are many types of sweet potatoes with edible foliage; some taste better than others. At my local swap I was fortunate to be given 7 slips for a Japanese edible-leaf type which I will keep in the house with great care until spring arrives. Wish me luck; if successful, I will be able to share.
