Deep purple, 4” flowers arise from spring through fall on the upright
vining growth of this vigorous climber. The growth habit of this selection is
more contained than many in the genus which lends itself to container growing
especially where space is limited. It can be maintained with pruning as an
upright potted plant or allowed to rise up and grow as a vine. We’ve successfully
trained Purple Allamanda as a standard with one seasonal pruning in late
winter, and it flowered nonstop from spring until late November here in CT.
Another positive attribute of Purple Allamanda is its strong root system that
gets it through the short days of winter with ease. It thrives in warm temperatures
with a full sun exposure.
