Added 11/21/08 I am regularly having people find my blog using a search engine to see if they can eat sweet potatoes from an ornamental plant. Please leave a comment to let me know whether you decided to eat your potatoes, and what you thought of them. If you do not have a blog, you can leave a comment by checking "Anonymous".
Added 11/11/10 I have other posts where I baked and eaten different kinds of ornamental sweet potatoes. Click here to see all the posts I've done on them.
My Marguerite potato vine produced a few tubers that I put aside last week. This afternoon, I Googled them to see if they are edible. I came across an old thread from iVillage Garden Web's Far North Gardening Forum, where people were saying they were edible, but there were differing views on the taste, and whether a person would want to eat them.
"Well," I thought to myself, "Here's an opportunity to be a photo-journalist and food tester!"
So, here is a photo of my vine, Ipomoea batatas 'Marguerite' taken 9/7/08. It's the lime green one in front. I don't remember if I checked the dark leaved sweet potato vine for tubers.
Here is the "harvest". It's not huge, but I thought I may as well see what they taste like, as I know I like sweet potatoes.
I put the potatoes on sensor cook, and my plan was to also time them to see how long they take to cook, but I forgot to. After a couple minutes, I heard a "pop" or two. I opened the microwave to see there was a little bursting, even though I had poked holes into them for steam to escape. I cleaned up the mess, put an extra paper towel over the potatoes, and let them finish the 2 minutes and few seconds that were left on the microwave.
Here they are, cooked! You can see the one that burst.
I am not photogenic! I had my husband take a few pictures, but deleted most of them. These aren't great, but here I am, seasoning a bit of the potato with pepper. I had already tasted a small bite, and it was sweeter and had a milder flavor than I had expected it to. I was pleased!
The verdict? If you like sweet potatoes, you will probably like these. My husband refused to taste them, as he does not like sweet potatoes. I think it's an awesome bonus from growing something you enjoy, even if it's just enough for a meal.
These weren't as moist as sweet potatoes, but with spray margarine, and a little salt and pepper, I enjoyed the rest of the potatoes with my supper. I should have gone out and cut some chives to put on them. They may have been moister if the smaller ones were cooked separately from the large one.
Next year, I'll pay more attention to any other sweet potato vines I plant, to see what kind of harvest they provide.
