Mandevilla (from Latin mandare meaning “to speak”) is a genus of flowering plants native to South America. They are often called asparagus vines because they grow on stalks up to several feet high and have slender stems with leaves resembling those of asparagus. Their common names include asparagus plant, stinking vine, stinkhorn vine, and stinkhorn bush. There are approximately 150 species of mandevillae. Some species produce edible fruits; others are poisonous.
All varieties of mandevilla have three main parts: a stem, a leaf-like branch, and a fruit.
Some species produce flowers only once each year while other types may bloom every two years or less frequently depending on environmental conditions. Flowers vary greatly in size and shape, coloration, fragrance, and taste. The flowers of some species are used medicinally, such as the seeds of the sweet potato plant. Other species are ornamental, including the common mandrake (Mandrax morrisii), which produces purple berries that resemble blackberries.
In tropical regions, most species occur along rivers and streams where they form dense stands of thousands of individual plants. All varieties of mandevilla have shallow roots that enable them to thrive in high-humidity environments. In these areas, they are often the dominant plants.
Most mandevilla species produce few seeds and many vegetative offshoots, a process known as ‘crown division’. Each plant can produce up to 12 offshoots from a single root system. The entire root system of each plant is clipped and each offshoot is placed in a container for distribution. Each container can hold up to 12 offshoots.
A typical mandevilla vine has a height of about 6 inches. The leaves are in pairs, pointed, with prominent veins. They are supported by long leaf stalks called petioles. The stems are reddish or green and may have small raised spots on them. The flowers are irregular in shape and bright green.
They are surrounded by star-shaped red structures called meristems. The red meristems and green flowers give the plant its distinctive color.
Dwarf varieties of mandevilla, such as ‘Mandarin’, grow only 3 to 4 inches in height. They thrive even in pots and containers with little garden space. They bloom profusely and continually if they are planted in a warm, sunny location.

How long do mandevillas bloom?
The blooming period of a mandevilla vine is from spring until autumn, but there are some varieties that bloom only in late spring. These late-flowering plants typically have maroon or purple leaves and stems, while the early types have green ones. Most of the plants bloom from August to September.
How do you take care of a mandevilla vine?
Like most plants, mandevillas should be kept in a location that is cool and shaded in the summer and sheltered from extreme cold in the winter. They should be watered twice each week and fertilized monthly with a balanced 10-10-10 NPK fertilizer. Be careful not to over water or over fertilize them, because this can cause them to become susceptible to fungus and mold diseases. Pruning them back hard each year will keep them from becoming leggy.
What type of soil do mandevillas like?
They like soil that is rich in organic matter, such as compost or rotted leaves. They prefer soil that has a pH level between 6 and 7.5, which is on the acidic side of the scale. If your soil is too basic (has a pH level higher than 7.5), they require extra iron. You can add an iron supplement to the soil when you plant them, and then fertilize them monthly with an iron-rich fertilizer. If your soil is too acidic (has a pH level lower than 6), they won’t be able to take up the nutrients that they need from the soil, so you will need to add an organic fertilizer suited to acid-loving plants.
Where do mandevillas come from?
Mandevillas are originally from the mountainous regions of Central and South America. Most of them come from the foothills of the Andes Mountains in Colombia, Ecuador, and Peru. In these regions they can be found at altitudes between 4,000 and 9,000 feet above sea level. They like it hot and are able to flourish in climates with temperatures that range from 35 to 95 degrees Fahrenheit.
How long have mandevillas been cultivated?
The earliest known records of man-devillas are from 1562, when they were found in the gardens of Emperor Akbar’s palace in India. They were probably brought there from South America by Spanish or Portuguese sailors. They became very popular during the Victorian era (1837 to 1901) when British colonists went to great lengths to import as many different types of plants and flowers from their former colony, India. They are still popular to this day in England, and the English gave them their name: mandevilla.
How many different types of mandevilla are there?
There are over 200 named varieties. They differ in height, leaf size and shape, flower size and color, blooming period, and seasonal hardiness.
What colors do the flowers come in?
Rose, white, pink, red, purple, and bi-colored flowers can all be found among the different varieties. Some varieties are solid colors, while others have a combination of colors in the petals.
