If you live in a hot part of the country, and if you like growing succulents, you might be interesting in growing an edible succulent vine called Basella. There is a green one and a red one. I grow both.
They taste like okra, and are best when cooked up in a stir fry.
I forgot to add that they grow from both seeds and cuttings. And are often called Malabar Spinach, but they don't taste like spinach. They taste a little bit like okra.
