What are Euphorbia Plants?
Euphorbia is a large and diverse genus of beautiful flowering plants known as “spurge” plants. Succulent characteristics characterize the plants in this genus.
They can be found in the deserts of Mexico, South Africa, and Madagascar. Spurge plants’ leaves, like those of other succulents, retain water.
Many people grow these cultivars in their living rooms or indoor gardens as ornamental varieties.
Euphorbia varieties are valued primarily for their stunning appearance, unique floral pattern, flowers, and crown of thorns.
The flowers lack petals, sepals, and other common parts, distinguishing them from other flowers.
Because these succulent shrubs can withstand drought and are easy to care for, they are becoming more popular with gardeners.
There are numerous Euphorbia plants, each with its own color and appearance.
Fortunately, most of these species can be found at your local garden centers and grown in your indoor garden.
Popular Euphorbia Plant Types
With over 2,000 species, the Euphorbia family is a large and diverse plant family. While many of these species are not commonly grown in home gardens, there are a few popular varieties to consider.
The Spurge plant is distinguished by its brightly colored flowers, which can be yellow, red, or purple. It is also well-known for its ability to spread quickly and cover large areas.
Here is a list of some of the most popular Euphorbia species.
Euphorbia Abyssinica
Desert candle spurge is another name for Euphorbia abyssinica.
It is found throughout the North African desert areas, including Ethiopia, Sudan, Somalia, and Eritrea.
This large tree-like succulent has woody stems. The leaves are fleshy and small. Surprisingly, scientists discovered that the root of this plant has anti-malarial chemo-suppressive properties [1].
This cultivar thrives in the rock garden. You must ensure that this Spurge receives plenty of sunlight.
We recommend that you provide them with at least 6 hours of direct sunlight. Make a growing medium that drains well.
In the growing and blooming seasons, water them sparingly and feed them organic fertilizer, which is good for them.
Euphorbia Ammak
Euphorbia ammak, also known as Candelabra Spurge, is a beautiful variety with a short trunk that stands upright. It appears to be a branched candelabra.
The surface of this plant is a creamy-yellow color. It can reach a height of 20 feet and a width of 8 feet.
As a result, if you intend to grow it indoors, make sure you have enough space for this Euphoria.
This plant thrives in direct sunlight but keeps it out of direct sunlight during the summer.
Brown scars on the stems indicate that your plant has been exposed to too much direct sunlight.
This desert cactus does not require much water, but excessive moisture can cause root rot.
Water them sparingly and poke holes in the bottoms of the containers.
Euphorbia Amygdaloides Var. Robbiae
Euphorbia amygdaloides var. robbiae is a species of Wood Spurge that resembles a beautiful ground cover and forms shiny, deep green colonies of stunning rosettes.

Other Euphorbia Plants
There are so many more types of Euphorbia plants out there. Unfortunately, we can’t list them out. Below are some other spurge plants to consider.
Euphorbia Lambii: Also known as the Tree Euphorbia or Truffula Tree, it is mainly planted outdoors as a landscaping plant. If you look at it, you would think it was a tree, but no, it’s just a funny-looking top-heavy Euphorbia plant. It will no doubt add curb appeal to your front yard.
Euphorbia Flanaganii: With the nickname of Medusa’s Head plant, it is an extremely unique succulent plant that has long, serpentine stems that look like the fabled creature Medusa’s serpentine hair. Snake-like snake-like stems or branches characterize this plant, which is unusual among the common succulents. Every single one has a Fibonacci spiral at its center, and there are no two alike.
Euphorbia Leucodendron: Most commonly known as the Cat Tails Euphorbia Plant. Under perfect conditions, Euphorbia leucodendron, a succulent shrub with spineless limbs, can develop into a small tree. It makes a great landscaping plant. It is indigenous to the subtropical region of Madagascar, where it can reach a height of up to 10 to 12 feet. It resembles Euphorbia tirucalli in many aspects, but it is not the same plant because its stems are much thinner and have fewer branches.
How to Care for Euphorbia Plants
Euphorbia is a large and diverse plant family, the majority of which are native to Africa and come in a variety of shapes and sizes.
Some are delicate and small, while others are large and robust. Depending on the species, euphorbias can be easy or difficult to care for.
Euphorbia plants, on the other hand, require little care and are extremely hardy.
Let’s take a look at their basic requirements for indoor growing.
Light
Euphorbia, like the other succulents, prefers full sun to thrive. Partial shade appears to be acceptable to them, but we recommend that you provide at least six hours of direct sunlight regularly.
If you live in a hotter climate, keeping them in the shade during the day is preferable.
However, you can grow them indoors year-round in cooler climates without any problems.
The light should not be too bright or intense; otherwise, your plant will burn out quickly. It also needs enough light to promote growth.
You may need two lights if they are grown inside. A single fluorescent bulb works well and provides adequate lighting.
We have found that an LED lamp with a high-output white spectrum produces better results than most incandescent bulbs.
Temperature and Humidity
Euphorbia succulents are native to warm, dry climates. As a result, they will thrive in warm environments. You may need to keep a close eye on them during the winter.
Temperatures in the tropical and subtropical zones range between 55 and 60 degrees Fahrenheit.
Humidity does not appear to be an issue because they enjoy both high and low humidity conditions.
However, if your home has air conditioning or central heating systems, ensure that these do not affect their growth.
You can also use humidifiers to help maintain moisture levels inside your house.
Soil
Because Euphorbia varieties are succulents, the potting mix must be well-drained and the container must have several holes beneath it.
Growing Euphorbias is best done in sandy soil with a slightly acidic pH. As a substrate material, you can also use peat moss or perlite.
When temperatures begin to rise in the spring, this is the best time of year to plant these plants.
If you live in a cold climate, wait until summer before replanting. Use a large pot to allow for growth once the plant starts to bloom.
Watering
When it comes to watering Euphorbia plants, you should proceed with caution. Allow the top few inches of surface soil to dry before watering.
They cannot, however, be submerged in water. Overwatering your Euphorbia plants can also kill them by drowning their roots.
Excessive moisture can cause root rot and fungus infections.
If the soil is already dry, don’t water your plants, even in arid areas. Remove any dead leaves from your plants before watering them.
Fertilizer
Fertilizer needs vary by species, but all require nutrients to grow to their full potential.
We recommend applying organic fertilizer in the early to late spring to promote growth.
The leaves of these plants turn yellow when they are deficient in certain minerals. If this occurs, it indicates that they require more nitrogen and phosphorus than other elements such as potassium and magnesium.
These fertilizers will aid in the development of your plant’s coloration. You may need to apply another dose every two weeks until the foliage turns green again.
Propagation
These plants can be grown by sowing seeds, which are notoriously tricky to germinate. You can also propagate by stem cutting if you don’t have this.
Plant the stem in a cactus mix after cutting it with a sharp and sterile knife. Keep in mind that the sap can irritate the body.
Allowing the cut portion to dry will increase the success rate of rooting.
If you have a mature or mother plant, you can cut the stem or leaf and propagate your plants with the cuttings.
Using a sterile knife, cut the stem just below the soil.
The space between the stem and the soil should be left for the next plant.
Before they can be planted in new soil, the baby plants will need time to develop and sprout roots.
Common Problems of Euphorbia Succulent Shrub
Although these plants are hardy, they can face problems and suffer from various diseases.
In this section, we will mention some of the common issues with euphorbia plants.
Soggy or wet soil
Soggy or wet soil conditions can kill these plants by causing root rot. Therefore, ensure that the container has drainage holes and that the potting medium is well-drained.
Stem Rot
Stem rotting is another common disease of Euphorbia varieties. You will see dark, rotted, and soft areas on the stems. Remove the infected plants if you notice these symptoms.
Overhead watering can increase the chance of fungal diseases or powdery mildew issues.
Pests
Spider mites and mealybugs can destroy the beautiful leaves of Euphorbias. Apply insecticides if these insects are noticed. It would be best to remove them as soon as possible because they become unmanageable when they start laying their eggs.
FAQ
Are Euphorbia plants considered cactus?
No, Euphorbia plants are not cactus plants. Euphorbias feature thorns, generally in pairs, on modified stems that are mistakenly misidentified as cacti. Plus, Euphorbias do not have areoles. However, cacti and Euphorbias both blossom with flowers, but their flowers are generally very distinct.
Are Spurge and Euphorbia the same?
Yes, Spurge and Euphorbia are the same plants. Spurge is the common name, whereas Euphorbia is the botanical name. Euphorbia is a vast and diversified genus of flowering plants of the spurge family, generally known as Spurge (Euphorbiaceae).
Is Euphorbia poisonous to touch?
Yes, Euphorbia plants are poisonous when touched. Common euphorbia plants are toxic and are considered a skin irritant that can lead to blistering. The milky sap secreted by a Euphorbia plant is the plant’s most dangerous component. If you get sap on your skin, thoroughly wash it off with soap and water. When sap hardens on the skin, it can’t be washed away with water, so soap or milk must be used to get it off. Only the milky sap of Euphorbia varieties is poisonous.
How long does it take for Euphorbia seeds to grow?
In cold weather, Euphorbia seeds take 2 to 6 months to germinate, whereas, in warm temperatures, it takes 1 to 2 weeks.
Euphorbias may be cultivated from seed, but they are notorious for being difficult to germinate. In the spring, sow seeds in a mixture of coarse sand and commercial seed growing mix.
Conclusion
Plants of the genus Euphorbia (or spurge) are hardy and popular ornamental plants grown in any garden. They can live in both cold and wet climates.
With their stunning foliage and bright blooms, these evergreen plants add to the overall beauty of the landscape. They thrive in both temperate and tropical climates.
Because they have fewer requirements, they can be easily grown indoors. They prefer soil that is moist but well-drained. You can water them whenever you want.
You can either plant them in the ground or use a cactus mix. You can propagate them with seeds or stem cuttings.
Avoid watering these plants in the fall because they go dormant during this time.
Finally, use organic fertilizers like bone meal, vermicompost, blood meal, and cow dung to increase flower production in the spring.
