Appearance
Golden Trumpet Plant appears to be a shrub. However it is a climber with delicate and woody stems. It can reach a height of 2 meters when planted on the ground, but can be taller when there is a support.

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