Mandevilla Persistence: Understanding Yearly Returns and Specialty Varieties

If you’re a gardening enthusiast or someone looking to add a splash of vibrant colors to your outdoor space, mandevilla plants might have caught your eye. Known for their stunning blooms and lush foliage, mandevillas are popular choices for gardens, balconies, and patios. However, one common question among gardeners is whether mandevillas come back every year.

In this article, we’ll delve into the perennial nature of mandevilla plants and explore what you need to know about their growth habits and care requirements.

Understanding Mandevilla Plants

Mandevilla plants, scientifically known as Mandevilla spp., are native to South and Central America. These tropical vines are prized for their large, trumpet-shaped flowers that come in various shades of pink, red, white, and yellow.

Mandevillas are typically grown as perennials in USDA hardiness zones 9 through 11, where the climate remains relatively warm throughout the year.

Perennial vs. Annual

The term “perennial” refers to plants that live for more than two years, while “annual” plants complete their life cycle within a single growing season. Mandevilla plants fall under the category of perennials in regions where the climate is conducive to their growth.

However, in colder climates, mandevillas are often treated as annuals or tender perennials due to their sensitivity to frost and cold temperatures.

Overwintering Mandevilla Plants

In regions where temperatures drop below freezing during winter, mandevilla plants may not survive outdoors. To ensure their survival, gardeners often bring mandevillas indoors or employ overwintering techniques.

Before the onset of winter, it’s crucial to prepare mandevilla plants for dormancy by gradually reducing watering and fertilizer applications. Once indoors, mandevillas should be placed in a bright location with temperatures above 50°F (10°C) to prevent cold damage.

Rejuvenating Mandevillas in Spring

As temperatures begin to warm up in spring, it’s time to rejuvenate mandevilla plants for the upcoming growing season. Prune back any dead or damaged growth, and repot the plants if necessary.

Gradually reintroduce mandevillas to outdoor conditions once the threat of frost has passed, ensuring they receive adequate sunlight, water, and nutrients to promote healthy growth and abundant flowering.

Care Tips for Year-Round Success

To ensure mandevillas thrive and return year after year, it’s essential to provide them with proper care throughout the growing season. Here are some tips for success:

Sunlight: Mandevilla plants prefer full sun to partial shade, so choose a location that receives at least six hours of sunlight per day.

Watering: Keep the soil evenly moist during the growing season, but avoid waterlogging, which can lead to root rot.

Fertilization: Feed mandevillas regularly with a balanced fertilizer to promote vigorous growth and prolific flowering.

Support: Provide support for mandevilla vines to climb, such as trellises, arbors, or fences, to showcase their cascading blooms.

Pest and Disease Control: Monitor mandevilla plants for pests like aphids, spider mites, and whiteflies, and promptly address any signs of disease to prevent damage.

Specialty Varieties of Mandevilla Plants

In addition to the classic varieties of mandevilla plants, there are several specialty varieties that offer unique colors, growth habits, and flower forms. Gardeners can choose from a range of cultivars to suit their preferences and garden design. Some popular specialty varieties include:

Sun Parasol Series: Known for their compact growth habit and prolific flowering, the Sun Parasol series offers a wide range of colors, including shades of pink, red, white, and yellow. These varieties are well-suited for containers, hanging baskets, and landscape plantings.

Brazillian Jasmine (Mandevilla laxa): Unlike the typical mandevilla vines, Brazillian Jasmine is a shrubby species with smaller, fragrant white flowers. It can be grown as a perennial in warmer climates or as an annual in cooler regions.

Giant Crimson Mandevilla (Mandevilla x amabilis): As the name suggests, this variety features large, deep crimson flowers that make a bold statement in the garden. It has a vigorous climbing habit and can reach heights of up to 20 feet with proper support.

Dipladenia: Often confused with mandevilla, dipladenia is a closely related genus that includes species with smaller flowers and more compact growth. Dipladenia cultivars come in various colors and are well-suited for smaller spaces or as indoor houseplants.

Exploring these specialty varieties allows gardeners to experiment with different colors, forms, and growth habits, adding diversity and interest to their garden landscape.

Biological Pests and Natural Predators

While mandevilla plants are relatively resistant to pests and diseases, they may still encounter some common biological pests in the garden. Understanding these pests and their natural predators can help gardeners effectively manage infestations without resorting to harsh chemical treatments. Here are some biological pests that may affect mandevilla plants:

Aphids: These small, sap-sucking insects can distort new growth and cause leaves to curl. Natural predators such as ladybugs, lacewings, and predatory wasps feed on aphids and help control their populations.

Spider Mites: These tiny arachnids feed on plant sap, causing yellowing leaves and fine webbing on the foliage. Predatory mites, thrips, and predatory insects like predatory mites and thrips can help keep spider mite populations in check.

Whiteflies: These small, moth-like insects feed on the undersides of leaves and can transmit viral diseases to mandevilla plants. Natural predators such as parasitic wasps, ladybugs, and predatory beetles prey on whiteflies and their larvae, reducing their numbers.

Frequently Asked Questions (FAQs)

Q: Do mandevilla plants come back every year?

A: Yes, mandevilla plants can return year after year in regions with mild winters, typically USDA hardiness zones 9 through 11. However, in colder climates, they may not survive winter outdoors and may need special care or overwintering indoors.

Q: What can I do to ensure my mandevilla plant returns each year?

A: To encourage the return of mandevilla plants, provide them with proper care, including well-draining soil, regular watering, and adequate sunlight. Additionally, protect them from frost during winter and consider overwintering indoors in colder climates.

Q: Are there any factors that may prevent mandevilla plants from coming back every year?

A: Yes, factors such as harsh winter conditions, improper care, or pest infestations can affect the ability of mandevilla plants to return each year. Providing optimal growing conditions and addressing any issues promptly can help improve their chances of survival and return.


In conclusion, mandevilla plants are indeed perennial in regions with mild winters, where they can thrive and return year after year with proper care.

However, in colder climates, mandevillas may be treated as annuals or tender perennials, requiring overwintering indoors to protect them from frost.

By understanding the growth habits and care requirements of mandevilla plants, gardeners can enjoy their spectacular blooms and lush foliage season after season, adding beauty and charm to their outdoor spaces.
