Is Dipladenia a Fast Grower?


Plants that were earlier categorised as belonging to the genus Dipladenia (Dipladenia spp.) are now considered to be members of the genus Mandevilla (Mandevilla spp.). If you don’t want the Dipladenia plants to take over the surrounding area, growing them in pots is a good choice. The plant hardiness zones 9 through 11 of the United States Department of Agriculture are ideal for growing mandevilla. In USDA zone 8, plants may be destroyed all the way to the roots, but they will eventually regenerate. If you live outside of these zones, you may grow them as annuals.


Within the Mandevilla genus, the species known as Dipladenia is known for its denser foliage and more gradual growth. Mandevilla plants are more vigorous than Dipladenia in their growth as vines.

Dipladenia or Mandevilla?

There are over one hundred different species of mandevilla, not to mention a large number of cultivars, and most of them have a rapid growth rate, with some variation depending on the variety and the growing circumstances. There are several species of Dipladenia and Mandevilla, both of which have a vining habit and lovely blooms that resemble trumpets. According to Garden Analyst, the genus Mandevilla was not identified for the first time until more than a century ago. At that time, the bigger forms of this plant were called Mandevilla, while the smaller, bushier variants were termed Dipladenia. Both of these plant species are now considered to be members of the genus Mandevilla, which has up to two hundred different tropical species and hybrids.

A beautiful climbing plant that can rapidly cover a trellis, arbour, or pergola, mandevilla may reach heights of up to 20 feet or more over its lifetime. Due to its shrubby nature, dipladenia may be used to create a stunning hanging basket or can be used to fill up a smaller area. It’s possible that you’re wondering whether or not dipladenia is an annual or a perennial. The fact of the matter is that it is determined by the region in which it is cultivated. Unless it is cultivated in one of the climatic zones with milder temperatures, it is classified as an annual.

Plant Care Today states that the Mandevilla genus of plants does, in fact, include certain representatives that are toxic to humans. Consuming mandevillas and dipladenias, despite the fact that they may not lead to life-threatening poisoning, is not a good idea since doing so can result in minor indigestion.

Growing Dipladenia in Containers

The dipladenia plant does not have a rapid growth rate. The climbing species of Mandevilla may reach heights of up to 6 to 8 feet in a shorter amount of time. When it comes to maintaining the form of your Dipladenia plants, you may prune them at any time of the year. It is crucial that the soil in containers used for cultivating Dipladenia has enough drainage if the plant is to thrive. A handful of crushed charcoal should be added to the mixture after it has been mixed with two parts peat moss, one part potting soil, and one part sharp sand. Mix well.

In the winter, you should only water your plants once a week, but you should water them until the water drains out of the drain holes. The soil should have an equal moisture content throughout the spring and summer, but in the autumn it should be allowed to dry out to the touch. When you plant or transplant your Dipladenia, be sure to save as much of the original root ball as you can. Put the container somewhere that will get light that is filtered or indirect. Because dipladenia thrive in warm environments, you shouldn’t take the container outside until the temperature has been reliably over 50 degrees Fahrenheit for at least a week.

Care for Dipladenia

Applying a fertiliser with a ratio of 10-20-10 every two weeks while the plant is developing will allow you to get the most height out of your Dipladenia plant throughout the growth season. When the plant is no longer producing new blooms, you should stop feeding it and start feeding it again in the spring, when the blossoms will once again begin to develop. If you want to maintain the form of your Dipladenia plant, you should start trimming it as soon as you see new growth in the spring. Creating a bushier plant may be accomplished by pinching back the growing tips.

Taking off the wasted flower heads gives the plant a cleaner look and helps prevent the spread of any diseases caused by fungi. It is simple to multiply Dipladenia plants in the event that you decide you need additional of these lovely plants. Plantopedia states that cuttings, layering, and sowing are the three methods that may be used in the propagation of dipladenia. If you prune the plant often throughout the spring, there should be a plentiful supply of new branches that may be utilised as cuttings. If you want to proceed in this manner, you should first place the branch in some rooting powder and then in cultivation soil.

The Rio Dipladenia is a well-liked type that may be seen rather often in nurseries. According to Home Depot, Rio Dipladenia is more drought resistant than other types of Dipladenia and may often be found in versions with pink, red, or white blooms. Because they attract a variety of pollinators, particularly butterflies, these stunning flowers in the form of a trumpet make a wonderful addition to the garden, whether they are planted in pots or directly into the ground.
