This versatile tropical vine can be used as an ideal accent plant, hedge, or as a specimen plant in the garden. Its vivid yellow trumpet-like flowers grace this plant during the spring and summer months. There are several varieties of allamanda; some dwarf varieties are perfect for baskets or as border plants along a garden path. The larger varieties can produce flowers up to 5 inches in diameter and are perfect to plant along a fence or a bare wall that might need some dressing up.
Allamandas are sun worshipers; they love bright sunlight for most of the day. They can also be planted in locations with some shade; however, they will not produce abundant crops of flowers. Plant in areas where there is good drainage. Water daily when planted in the landscape until established. After established, water as needed, especially during the hot summer. If planted in containers, water consistently when the top inch of soil feels dry to the touch, do not overwater. For best results, fertilize in early spring and summer. Prune allamandas gently throughout the growing season to help maintain their shape.
Note: These plants are grown for decorative purposes and are not intended for human or animal consumption
