Positive Monocromatico On Apr 22, 2004, Monocromatico from Rio de Janeiro
Brazil (Zone 11) wrote:

This Allamanda comes from dry areas of the northeastern region of Brazil. This is a leggy shrub, reaching up to 3 meters tall, with long and erect branches that bear leaves only on its tips, the rest of the plant stays nude.

These leaves are much longer than the usual Allamanda ones, but still have that toxic white sap. These leaves are concentrated, 3 to 4 per node, with very short internodes. This vegetative appearance is what distinguishes this species from the others. The flowers are big, yellow, trumpet shaped, pretty much like any other Allamanda. The seed pods are round, spiny, and produce many seeds under ideal conditions.

This plant likes a relatively dry and hot climate, though some watering would be necessary sometimes. It likes fertile and well drained soils and full sun. It doesn´t tolerate low temperatures.


This plant has been said to grow in the following regions:

Spring Valley, California
Carriere, Mississippi
