Opuntia is a large genus of plants native to North America and South America. All have succulent stems, some of them becoming woody with age. Stems may be cylindrical or flattened pads. Tiny, succulent leaves may be present on the newest growth (see photo below.) Most species are spiny.
Black-eyed Susan Vine (Thunbergia alata) is native to Africa. Thunbergia is a long trailing vine that is sometimes used to cover fences, but it can be pruned back. Pruned vines will branch, and the flexible branches can easily be trained to drape as filler flowers for containers or from hanging baskets.
