Plant Care Guide >> Outdoor Shrubs >> Allamanda
Allamanda is a handsome evergreen, twining climber that grows vigorously in its preferred tropical climate. It has dark green, leathery leaves and carries its golden yellow, trumpet-shaped flowers over a very long period. Allamandas are used throughout the tropics as ornamentals. They are easy to grow, in warm conditions.
Common name:

Allamanda, Golden-trumpet

Botanical Name:

Allamanda cathartica




Light green, glossy leaves are produced on slender, green, twining stems which become woody with age. The leaves are smooth, thick and pointed.


Up to 6 inches in diameter (15 cm), trumpet shaped, single or double, yellow flowers. The plant flowers all the year round.


Requires full sunny locations for best flowering. Few flowers are produced in locations receiving only three to four hours of sun.


They are easy to grow, in warm conditions.


Needs well-drained soil enriched with decayed organic matter. Will also benefit from a mulch of compost or manure.


The plant requires moderate humidity.


Needs regular, deep watering during summer but should be kept rather dry during winter.

Pest and Problems:

Allamanda is only occasionally bothered by caterpillars or mites.

Growth habit:

It is a fast grower. It grows into a vine but can also be trimmed to be used as a shrub.


Feed your plant with a 5-10-5 liquid fertilizer, mixed at half strength.


With proper pruning, it makes a very attractive free-standing specimen shrub. Regularpinching will keep the plant in bounds.


Propagation is done from cuttings.

Special Care:

All parts of the plant are considered poisonous and highly cathartic. Because Allamanda is such a prolific bloomer, give it a rest during the winter months, watering less, and no fertilizer.

Landscaping Utility:

It can be used as a shrub it kept pruned or it can be used as a vine on tellis. The distance of planting should be 2.5 feet c/c.
