Exotic Plant Insight: Brugmansia Arborea

Brugmansia arborea is an evergreen shrub or small tree reaching up to 7 metres (23 ft) in height. The ovate leaves have coarsely toothed margins when in their best condition. The leaves, flower stalks, fruit, and especially the young shoots are covered with fine velvety white down. Flowers are strongly fragrant, trumpet-shaped, nodding to sub-horizontal, white to ivory-white or cream. At 12–17 centimetres (4.7–6.7 in) long, the flowers are the shortest of all Brugmansia. Flowers are produced almost continuously in smaller quantities, unlike many other Brugmansia that flower in larger flushes. The ovoid fruit have an average length of 6 centimetres (2.4 in) and width of 4.5 centimetres (1.8 in). The calyx is slit along one side and is very long in relation to the flower, and in this respect is often used as a quick check to verify correct identification. With a few exceptions, the green calyx usually reaches down almost all the way to the flower corolla's mouth.

They are native to the Andes mountains of southern Colombia, Ecuador, Peru, western Bolivia, and northern Chile. As the hardiest of all Brugmansia species in regards to both cold and drought, they are often found in the drier valleys of the Andes, in areas with an annual rainfall of 400 to1,400 mm. Occurring at elevations of 2000 to 3000 m, it is not uncommon for them to receive light frosts.

Brugmansia arborea are usually pollinated by moths. They are attracted by the white color of the flowers and their fragrance that gets stronger in the evenings.

Growing conditions: Hardiness zones 9 to 11, (-5°C/25°F, 4°C/40°F- see map below) in winter. It will stand short frosts, but generally does best in areas where the temperature rarely drops below 32°F. Provide a minimum winter temperature of 7°C and reduce watering over the winter. In cold winter areas, plants can be brought indoors.
