and annuals is widespread throughout the tropics.It includes sweet
potato and some of the loveliest of the tropical flowering vines.

fragrant flowers which in many species wither by midday.
The flowers are usually short lived, lasting only one day (or
night), but blooming prolifically and in succession. They are useful
for covering sheds, fences, trellises and banks, and may also be
grown in pots.
Flowering colors: Blue, Crimson, Mauve, Orange, Pink, Purple, Red,
Scarlet, White, Yellow
Cultivation: . They prefer moderately fertile, well-drained soil and
a sunny position. Care should be taken when choosing species, as
some can become extremely invasive in warm districts.
