Edward F. Gilman2

Introduction

This evergreen, spreading and climbing vine is covered with vivid flowers in the warm months (Figure 1). Lavender-red, trumpet shaped flowers explode into bloom during the warm months and cover the vine in vibrant color. The spiny, yellowgreen fruit follows and can be seen on the plant simultaneously with the spectacular blooms.

Use and Management

The dark green, glossy leaves are produced on slender, green, twining stems which become woody with age. Blooming during the warm months of the year, Allamanda should only be planted in frost-free locations, although it could be grown as an annual in colder climates due to its rapid growth rate.

The erect sprawling growth habit makes it ideal for quick coverage of trellises, arbors, or on a tree trunk. Many people use it to cover the base of a mail box or pole. Allamanda will cascade over a retaining wall and makes a nice hanging basket. Rapid growth creates a sprawling form with individual shoots growing alone, away from the rest of the plant. Regular pinching will keep the plant in bounds, but too much pinching removes flower buds which form on new growth.

Requiring full sun locations for best flowering (some flowers are produced in locations receiving only 3 to 4 hours of sun), Allamanda is tolerant of various soil types and requires only moderate moisture. Regular, light fertilization during the growing season helps promote growth and flowering.

Pests and Diseases

A witches broom can deform Allamanda.
