This member of the Convolvulaceae family was given this name by Robert Sweet in 1826. It is found all the way from the tropical Africa throughout Asia, and have furthermore been spread in Australia, southern North America and other warm places. It preferring a rich but well drained soil with some to much water and some sun. The caudex can grow to five centimetres in diameter, and rather long. The vines can reach two to five meters. The large flowers are lavender.

The generic name Ipomoea is derived from the Greek ἴψ, ἰπός; íps, ipós, meaning 'woodworm', and ὅμοιος; hómoios, meaning 'resembling'. It referring to their twining habit.  The species name means 'from Cairo'.
