Growing tips

If growing in cooler climates, they will require plenty of protection from frosts. Best performance is seen in the warmer more tropical climates.
Allamandas are sprawling climbers and if growing on a trellis or wall will require plenty of support to grow.
They can be grown as a low hedge like plant or ground cover. Regular pruning and maintenance is required to maintain shape and form.
Wear gloves when pruning to protect your skin from the milky sap.
Some species are classified as Environmnetal Weeds in tropical areas. Check with your local council for further information.
