Mandevilla

A classic tropical vine, mandevilla is a great way to add a splash of color to any vertical space in a garden. With big, showy blooms that continue all summer and the fact that the plant is low-maintenance makes it a top vine choice. Mandevilla vines (sometimes called diplodenia) have seen a resurgence in popularity and breeding work is being done to continue to expand the vine’s varieties.

Flowering Vines for Color

Mandevillas are all about the blooms. Big, tropical blooms. Traditionally blooms come in shades of pink, red, and white and many shades in between. Now there’s a new color added to the range, a beautiful apricot. The large five-petaled blooms often have a rich golden throat inside that adds to the tropical look. Flowers are born in clusters that will continue to grow and add more buds all the time. Be careful not to damage these growing points of the bloom clusters or new buds will not form on that stalk. The size of the blooms can vary quite a bit depending on the variety. In general, smaller flowers tend to be much more abundant, and the larger blooms are a little more sparse, but quite grand.

These are some of our favorite flowering vines.

Mandevilla Care

As far as care goes for these plants, they are low maintenance. Like most vigorous plants that bloom for long periods of time, they will benefit from a good dose of fertilizer every once in a while. While mandevilla is an annual vine, it can be overwintered. When planting, it’s important to note that mandevilla is poisonous if ingested. Place the plant in a spot away from curious kids or pets. The milky sap it exudes when cut can also cause sensitivity in some people if it comes in contact with skin.

If the plants get a little too crazy for your liking, mandevilla can be pruned or trained. This can actually help to encourage more branching, and eventually, more blooms.

New Mandevilla Varieties

Initially, all mandevillas were climbing and vining plants. More recently, horticulturists and scientists have reined them in and shrunk them down. Many of the newer varieties are great options for hanging baskets and even spilling out of a container. Branching has also been improved, creating much bushier plants, and more blooming potential.

With all of the work to shrink these plants down in size, foliage can be quite variable between varieties. Older varieties tend to have much larger leaves that are a little rougher in texture and have more pronounced veins. The smaller, shrubbier types tend to have smaller leaves that are generally smooth and usually fairly glossy. The smaller leaves tend to showcase the blooms more.

Growing Mandevilla Vines Indoors

Mendevilla plants are gorgeous vines known for their lush flowers. Many people like to grow them on their balconies and patios. However, it is not always possible to grow your Mandevilla outdoors. These are not winter-hardy plants so they need warm temperatures to thrive.

Mandevilla vines require temperatures of at least 50 degrees F (10 degrees C) to thrive. It means that you cannot grow them outdoors yearlong unless you live in a warm climate. Most of the United States is not hot enough for this. It means that you will probably need to take your Mandevilla plant indoor for the winter or to grow it indoors for the whole year.

How to Grow Mandevilla Plant Indoors?

Mandevilla plants are not difficult to grow indoors, but you need to follow some guidelines. First of all, keep in mind that Mandevilla vine can take up some space. In the nature, these plants can grow up to 30 feet in height and length. Most houseplants don’t grow that big but they do take some space. Keep this in mind when deciding to grow Mandevillas indoors.

You will need to take your Mandevilla vine inside before the temperatures go lower than 50 degrees F. Take your plant inside and give it plenty of space. It is important to keep your Mandevilla in a room that is warmer than 60 degrees F.

Before you take your Mandevilla inside, make sure it’s free of pests. In case there are some pests, you need to get rid of them before you take your Mandevilla vine inside.

Another good practice before taking your vine indoors is to cut the plant by one third. In case your Mandevilla is too big, you can also trim it so it can fit the room without taking too much space.

If you have a greenhouse or a similar environment, perfect. This is ideal growing condition for your Mandevilla during winter. However, you may also place your plant near a sunny window, just make sure you can provide some shade for it. It is important to place your Mandevilla somewhere where it can get bright indirect light. Make sure to water it when the soil feels dry to the touch.

It is important to provide adequate light for your Mandevilla. Outdoors, they need regular fertilizing and watering. However, Mandevillas are dormant in winter so you should not worry about that. You need to cut watering in half during the dormant period. It is important that your Mandevilla stays relatively dry during this period to prevent rotting.

You may notice that your Mandevilla loses some of its leaves during winter. This is normal and it will regrow the leaves in spring, once the air warms up.

Your Mandevilla will probably not flower when it’s placed indoors. Making your vine bloom requires too much artificial light so it may not be worth it. Plus, remember that your Mandevilla is dormant during winter so you should not disturb this natural process.

In the Spring

Once the temperatures rise above 50 degrees F (10 degrees C) in the spring you can move your vine back outside. Before you move your Mandevilla to the patio or balcony make sure to remove any dead leaves. Your Mandevilla plant will thrive outdoors through the summer.

You should notice that your Mandevilla develops sprouts in early spring. This is the sign that you should move it to a sunny location and, if conditions and temperatures allow, to the balcony or patio. Make sure to start fertilizing your Mandevilla every two weeks to make it thrive. Use high phosphorous plant food for fertilizing. This is a great way to make your Mandevilla grow even stronger and to produce beautiful flowers.

Question: This year I bought and grew a beautiful Mandevilla vine in a pot with a small trellis on my deck. It was stunning and is still blooming like crazy. I know this is a tropical plant. Can I save it indoors or in the garage over the winter and bring it out again next year?

Answer: Mandevilla is a genus of perennial tropical vines native to Central and South America. Over the past few years, a few species and their crosses have been domesticated and have become more widely available at Pacific Northwest nurseries and home-supply garden departments.
With large trumpet-shaped flowers and glossy leaves, Mandevilla vines are a lovely addition to any garden. But unless you take special care, you will lose these beauties once the temperature falls below 50 degrees outside. There is one hardier type, Mandevilla laxa, or Chilean jasmine (not really a jasmine), that is a little more hardy and can stand temperatures into the 40s.
To save your Mandevilla vine for next year, I learned from the New York Botanical Garden website that you’ll need to protect it from temperatures below 50 degrees. This means moving it to a warm shelter.

If your Mandevilla is in the ground, you’ll need to prune it back when the weather cools down later this month, dig it up and put it in a pot with rich, well-drained soil. I’m lucky, as I decided to plant mine in a large pot after I bought it. So mine will not need digging up; it will only need cutting back before i move it to a warm shelter.
A bright sunny window in a cooler room is the perfect place to locate your potted Mandevilla. The room should stay above 60 degrees if you don’t want it to go dormant. If it does go dormant, you’ll know; it will shed all its leaves. Water infrequently over the cold months. It can go outside again next spring.
Or you can let it go dormant in a cooler garage or basement. Move your potted vine into an area that stays above 50 degrees. It will go dormant and lose all its leaves. Next April, bring it into a sunny window, fertilize it, then move it outside when the weather gets above 50 degrees at night.

Another option is to take and start cuttings and overwinter the smaller plants in the house.
Whether your Mandevilla overwinters in the house or in the garage, don’t fertilize it until late winter. Water it infrequently. It likes to be kept on the dry side when dormant.
If you have a heated greenhouse, you can keep your Mandevilla growing all winter if the temperature is kept at 65 degrees or higher. If it is below 60 degrees, but above 50, it may go dormant.
Mandevilla flowers on new growth, so if you give it an early spring dose of fertilizer once it starts growing again, it will flower earlier for you next year.
Mandevilla is in the Apocynaceae family, the Dogbane family. They have a milky latex sap that may irritate your skin, so wear garden gloves while cutting it back.
More than ever, tropical vines are available for sale as summer plants. In addition to Mandevilla, passion flower (Passiflora) vines and black-eyed Susan vines (Thurnbergia) are found in Pacific Norhtwest garden stores. These can be saved by being brought indoors in the winter as well. I have managed to overwinter blue passion flower on the south side of my house a couple of times. But if the winter has any hard freezes, you will likely lose them outdoors.
