Kolambi Flower – Golden Trumpet Vine

Although common in India as a garden plant, Kolambi or Golden Trumpet Vine is a native of the South America, including Brazil and its neighboring countries. It might have been introduced in other parts.

The bright yellow flowers of this plant look like trumpets. It can also be compared to a funnel or a Gramaphone (an old device to play music). Funnily, it is called Kolambi Flower because it is quite similar to a pot used to spit, which also has the same name.

Leaves & Stem

The oblong leaves of Kolambi have a shiny texture. They grow densely on the stem and has very short petioles. Because of its dark green color and thick foliage, the plant always gives an evergreen appearance.

The woody stem is usually green or brown. They can climb over adjacent plants. Without pruning, the stems/vines can grow easily and spread over a meter on the ground. So in gardens, the vines are tied together to keep them erect.

The leaves and stem have a latex which can be poisonous and can also cause itching or other irritations.


The yellow flowers have 5 petals which have pointed tips. They might slightly resemble a lotus petal with a wide middle part.
