I know that the buds are edible and occasionally make them. They are also great stuffed (I usually use spinach and feta or other cheese) then dipped in a tempura batter and deep fried. I do the same with squash blossoms. I have no idea what they do with the bulbs. They don't look particularly appetizing though. lol Thanks for that info Carol. I'll keep them in the pot for now. Do all the bulbs carry the virus? If not how can you tell if they are infected?

It may or may not be Ipomoea batatas (sweet potato) but definitely looks like an Ipomoea of some type. (The genus also of morning glories, moonflower vines, and a myriad of others.) Their leaves can wildly change shape and size, among individuals of same type, and in phases on a same plant. I would lean toward I. batatas since it's not blooming now. Most Ipomoeas are in bloom at this time. I. batatas can bloom, but often chooses not to. The amount of sun it's getting may be affecting the status of blooms, if it's one that would otherwise be blooming now.

Over the last year I've added 2 varieties of apples, purple leafed plum, lavenders, german chamomile, roman chamomile, chicory, yarrow, elderberry, wolfberry, another hazelnut, borage, garlic, and comfrey, as well as veggies like peppers, tomatoes, radishes, scarlet runner beans, and I've just sown 2 varieties of kale. I added some things a bit late (I just recently found out about edible forest gardens!), so I may need to replace a couple of things that look iffy. This fall I'm hoping to add raspberries, thornless blackberries, red currants, grape vine, and a mulberry.

Wild passion fruit - technically edible, but tasteless. I've used the berries for dying Easter eggs a pretty Wedgewood blue. Also a host plant for fritillaries & zebra longwing butterflies. If you check out the flowers, you'll see that they are perfect miniature passionflowers, only green.
