There are two forms of this plant, a large, climbing woody vine or a shrub. The shrub
generally grows 4 to 5 feet. The vine will grow over anything and is a prolific bloomer.
The big yellow funnel-shaped flowers are mostly at the end of the branches. The leaves are
smooth, thick, opposite and pointed. If spent flowers are not deadheaded, rounded,
prickly, burlike fruits will form. These fruits split to release winged seeds. Yellow
allamanda has a white milky sap in all parts, which oozes out as soon as it is broken. The
milky latex (sap) may cause illness and rash in sensitive people and large doses may cause
vomiting. The sap also protects this plant from harmful insects except the
"frangipani caterpillar", which can cope with the toxins in the leaves.
Other Names - yellow allamanda, golden trumpet, yellow bell, angel's trumpet, buttercup flower, bunga akar kuning, wilkens-bita, llamarada, brownbud.
