Common name: Purple Allamanda
Botanical name: Allamanda blanchetii Family: Apocynaceae (oleander family)
Synonyms: Allamanda violacea
This shrubby climber is an Allamanda hybrid or selection of unknown origin
with large ( 4"-6") deep purple flowers. There is a more common selection
known as Allamanda "Cherries Jubilee" which has lighter purple flowers with
yellow in the throat. Allamandas come from tropical South America.
Allamanda is in the Apocynaceae family which includes Plumeria, Carissa,
Ochrosia, Adenium, Mandevilla, Nerium oleander, Thevetia and others. All
plants with milky sap like these (also typical of the castor family) are
potentially toxic - though a few, like Carissa, are not. One can identify
this family easily by the trumpet-shaped flowers that have radially
symmetrical lobes that are usually twisted like little propeller blades as
well as the milky sap.
