Grows as a vine-like shrub when it is young. The light yellow, trumpet-like blossoms appear on the tips of new growth and from side branches on the vine. Flowers bloom almost year-round, although the plant is not covered with flowers like the Allamanda.
Hummingbirds and butterflies will visit the blossoms.

Make sure watering is done once the soil goes dry. Although the soil can remain moist, but it should not turn soggy/wet. Having drainage hole in the pots goes a long way in ensuring there is no water stagnating on top of the soil. You can spray the plant occasionally.
Fertilise the plant once a month in summers however Don't feed any fertiliser in winters. Giving fertiliser to the plant ensures nutrients going in which keeps it healthy. Keep an eye on the leaves of the plant to know any symptoms for watering or sunlight.
