This is an extremely rare ipomoea species from Africa. The small, lavender flowers are followed by fuzzy, orange seeds.
Ipomoea transvaalensis has smaller flowers and foliage than Ipomoea purpurea. It is useful as either a groundcover or a trellised vine. The seeds have a very hard coat that must be nicked before they are soaked. If they don't swell up the first time, nick and soak them again. Also known as Transvaal Orange-Seeded Morning Glory.
