What is an Orange Azalea?

The orange azalea is also known as Mandarin Azalea or Mandarin Lights Azalea a flowering shrub that belongs to the genus Rhododendron. It’s also called R. recurvum, or sometimes just “azaleas.” It is a large, deciduous shrub that produces bright orange flowers in the spring. It can grow up to eight feet tall and blooms for many weeks at a time. People mostly use them as garden plants because they like their orange blossoms and the way they bloom early in the spring.

Orange azaleas have shiny, orange-red leaves—and green ones too! They also come in a bunch of different sizes: from really tall to really short. One thing that makes them so special is how big their flowers can get: up to a foot across.

Origins of Orange Azalea

The orange azalea is one of the most beautiful flowers you will ever see. Its vibrant orange colour and delicate petals make it a pleasure to behold. The orange azalea originated from Japan around 1888 but has been grown worldwide since its introduction to North America in 1919. There are many orange azalea varieties, including ‘Jervis’, ‘Prince of Orange’ and the more well-known ‘Christine Stevens’.

Orange azaleas are known for their bright orange blooms that bloom from late winter to early summer (February-April). There are many varieties of orange azalea plants with different colours on each branch.

The orange colour comes from pigments that are produced by certain plants to defend themselves against insects or diseases that may harm them. This pigment is called orange betalain, and it is found in a variety of plants.

Orange Azalea Plant Care Guide

The azalea orange plant has been extremely popular in recent years, as it’s easy to grow and likes climates similar to what is seen in Southern Europe or California. It also does well indoors if you live near cold regions with long winters. Here are some care guides.


The orange azalea should be in soil that drains well. Sandy or clay soils are not recommended for orange azaleas as they do not drain water, which leads to stagnant pools of water and disease problems. Many orange azalea growers are of the opinion that orange azaleas need soil with a pH level between six and seven. An excellent choice is loose loamy soil with organic matter mixed in such as peat moss, composted leaves or bark chips.

The best way to test your soil is using a pH meter or kit, which will give you an indication of how acidic it is. Anything from around neutral up to about pH level eight can be used.


Orange azaleas love full sun but don’t like it getting too hot. If orange azalea is starting to look droopy in the afternoon or evening it’s time for shade! A little bit of morning light is okay and orange azalea will still be happy if they get a few hours of direct sunlight per day, just make sure it’s not all day.

Shade cloth, orange azalea tree coverups are a great way to protect your orange azaleas from the heat. If you have a garden with orange azaleas, try and use some natural barriers like trees or bushes so they get good morning light but not too much heat in the afternoon.

orange azaleaWatering

Watering orange azaleas is not as complicated as one might think. Full, frequent watering will produce more flowers but it also can lead to root rot and other problems if you’re not careful. The best way to water orange azaleas is by giving them a deep soaking once every five or six days in the summer. In the winter, orange azalea should be watered every two to three weeks.

It is best not to water orange azaleas from overhead because this can lead to leaf scorch and other problems. Instead, use a watering can or hose attachment that will allow you to reach down into the root zone of your plant. This ensures that the orange azalea will be watered thoroughly without getting wet leaves.

If orange azaleas are in pots, use a soaker hose or other type of irrigation to ensure that they’re watered deeply and sufficiently.


Orange azalea can thrive in temperate climates, but it is cold-hardy and thrives in areas cooler than orange pomelo. Keep orange azalea warm during winter months with a 40°F minimum temperature when dormant. There are orange seedlings that have been developed to withstand more extreme temperatures so research what will work best in your climate.

While the plant can handle some cold weather, it cannot tolerate an environment where evening temperatures remain above 65 degrees F year-round. Avoid planting orange azaleas near concrete or other heat sources to prevent them from burning up during hot spells.


Humidity is essential for orange azalea trees. Aim to keep humidity levels at least 50%. During winter and spring, this can be achieved by misting the plant with a spray bottle once a day. If you don’t have access to water all year round, use an ultrasonic humidifier in your home during these periods. In summer, orange azalea trees enjoy being outside in the shade.


The orange azalea needs to be fertilised with a good, balanced fertilizer. Use either: manure, nitrate of potash (N), or slow release pellets such as Osmocote®.

  • Manure is the most natural option and can make use of any leftovers from your lawn mowing or weeding duties. It provides a good balance of nitrogen and other nutrients that orange azalea need.
  • Potash fertilizer is a great option for orange azaleas in containers or with restricted root space, as it releases its nutrient slowly over time. The orange azalea will be less likely to suffer from the effects of too much nitrate leaching into the ground.
  • Slow-release pellets such as Osmocote® are good for orange azaleas in containers or with restricted root space, and will provide a steady supply of nitrogen to your orange azalea. It is also easy on the environment because there’s no need to apply it too often.


Toxicity from orange azalea is only a concern when ingested. The sap can cause irritation to the skin, eyes and mouth if contacted

Inhalation of orange azalea smoke can be hazardous in high concentrations due to the presence of coumarin or other toxic compounds which may lead to liver failure. However, this risk is low as orange azalea is not a preferred material for smoking.

Azaleas are toxic to cats, dogs and horses. They should not be planted in areas accessible by animals or children. There is a specific type of azalea that has been bred for toxicity-safety called the Toxicity Free Azalea (TFA).


The orange azalea has a wide variety of flowers that can bloom throughout the entire year. This means they will need to be pruned often and many times severely so their branches don’t become too heavy with weight. Pruning is best done in early spring but it’s important not to do this during winter when plants are resting or mid-summer when plants are trying to produce flowers.


Orange azaleas are sold by many nurseries that propagate orange azalea from cuttings, or seeds. The propagation of orange azalea needs to be done in winter when the plants have fewer leaves and less active growth. This is because orange azalea’s need a cold period before they will sprout new buds for the next spring. Cuttings should be taken from orange azalea in the winter using clean, sharp pruners and placed into a growing media to start rooting.

The orange azalea seeds can be collected and planted in the fall, stratified for six weeks at 45 degrees Fahrenheit (F) to break their winter dormancy, then placed in a cold frame or pot with soil over them until they sprout. A cutting of an orange azalea can be taken in the spring from a healthy plant, and it will take root quickly.


Orange azaleas are great houseplants because they have a lot of colour and beauty. But it is important to know how to take care of orange azalea so that you can keep your plant healthy for the long term. It’s easy enough to repot an orange azalea, but there are a few things you need to know beforehand.

Orange azaleas have delicate, brittle branches which means they should not be repotted during the summer months when plants are most active and prone to damage from transplanting. The best time for orange azalea repotting is in early fall or winter. Make sure your orange azalea has a pot that is at least three times the diameter and height of its current container, as well as fresh soil.

Before repotting orange azaleas, it is best to remove the foliage from below the soil line and using a sharp tool like scissors or pruning shears. This will help you see any roots that are growing inside of the pot where they should not be, such as at the bottom of a container.

When repotting orange azalea plants, be aware that they are fragile and should not be handled roughly. It’s best to use a small shovel or trowel for the task of digging up orange azaleas from their pot as this will prevent damaging roots while still allowing you to get them out of the container.

Plant Disease

At times, orange azalea can be susceptible to a number of diseases and problems. The most common one is leaf wilt disease which leads to wilting leaves that eventually dry up if they are not treated. Leaf spot on the other hand causes yellow spots with black borders in between them on the foliage of orange azalea while powdery mildew leaves orange spots on the foliage.

Rust is another orange azalea disease that causes orange or brown splotches on the leaf margin as well as yellowish spots and lesions are often seen on the upper surface of a leaf blade. These are some common orange azalea diseases, but there are others such as root rot which causes orange azalea leaves to turn brown and shrivel up.

Orange Azalea Variegated

The orange azalea is a variegated variety of the North American native shrub, Rhododendron canescens. It’s also commonly known as orange fiesta azalea or orange tree periwinkle and has an orange flower colour on its leaves with green margins. The orange azalea originally found in the wild is orange with green margins. This particular orange azalea is a hybrid of R. canescens and an undetermined species, most likely native to Asia or Japan, that was first introduced in 1962 by J. Denny & Sons near Charleston, South Carolina

There are many different varieties that resulted from crossbreeding this orange fiesta azalea, such as orange African sunset azaleas and orange cardinal azaleas. The most recognizable orange variety is the orange Alabama sunshine which has a deeper orange flower colour than the original orange fiesta azalea. The variegated leaves of this particular plant make it stand out among other plants and give it a lovely orange shade.

Common Issues with Orange Azalea

Even with proper care, orange azalea can often develop common pests or issues. The most common pest for orange azalea is the aphid. This has a round shape and feeds on sap from the leaves of an orange azalea plant by sucking it up through their mouthparts. If they are not controlled early, these insects can hinder growth and cause yellowing leaves.

To combat these insects, orange azalea owners should spray the plant with a strong stream of water from time to time. This helps remove any sap that is attracting aphids in order for them not to feed on it.

Orange azaleas are often susceptible to root rot due to their shallow root systems. To prevent this, orange azalea owners should add mulch around the plants to increase moisture and help with drainage.

Fungal diseases are often a problem for orange azaleas due to their susceptibility to wet conditions. Fungicides can be applied as necessary but it is important that they not come into contact with plant leaves.

Orange azaleas are also susceptible to leaf spots, which can be caused by water splashing up onto the leaves from either rain or the watering of orange azalea plants. To prevent this, orange azalea owners should try not to water the plant on days when it is raining heavily and avoid excessive overhead watering as well.
