About Euphorbia Lactea
Native to tropical regions of Asia, Euphorbia Lactea is a form of spurge. In its native setting, it grown as an outdoor ornamental plant; however, it can also be grown as a houseplant in temperate regions.
Easy to grow and quite unusual looking, mottled spurge will create a stunning display when featured as a part of your landscape or inside your home.
As mentioned, Euphorbia Lactea is succulent shrub or small tree. It can grow as tall as 16 feet and it features several branches that can reach a thickness of about 2 inches.
The branches of the shrub feature several cross-sections, which are covered with spine-like growths.
The spiny portions of the plant measure about ½ inch thick, and overtime, they start to develop small-sized leaves. The end portions of each individual section on the plant, as well as the leaves, are reddish in color. Leaves of the plant are small and deciduous, meaning that they fall and regrow each year; however, not all plants produce leaves.
The size a fully grown Euphorbia Lactea varies. When planted in the ground and gown in optimal conditions, mottled spurge can reach heights of up to 16 feet or more. When grown in a container, it can reach heights of 2 feet.
In terms of blooms and fragrance, the mottled spurge only produces a minimal amount of flowers, if at all. Even flowering Euphorbia Lactea, however, does not produce a fragrance. Though it does not consistently produce flowers and there is no fragrance, the leaves and stems of mottled spurge do offer a showy appearance.

Euphorbia Lactea Growing Tips
If you’re interested in growing Euphorbia Lactea, let’s take a look at some tips that can lead to growing success.
Where to Plant Euphorbia Lactea
While mottled spurge can tolerate temperatures that fall to 30 degrees, it can only tolerate such temperatures for a very short period of time.
If you live in a location where the temperatures are warm year-round, this succulent shrub can be planted outdoors.
If you live in a region where the temperature falls to 30 degrees or lower, growing it in a container that can be brought indoors when the cold season arrives or leaving it indoors year-round is recommended.
Euphorbia Lactea, like all succulents, requires large amounts of sunlight; however, it should not be exposed to direct sunlight for prolonged periods of time, as harsh UV rays – especially during the high heat of the day – can damage the leaves and branches.
Therefore, if you are planting it outdoors, choose location that receives partial sun to partial shade. If you are planting it indoors, select a room that receives ample amounts of sunlight; in locations in the Northern Hemisphere, for example, a south-facing window would be idea.
If planting in a container, make sure to choose a container that features a drainage hole. Euphorbia Lactea can suffer from root rot or can drown if it sits in large amounts of water for long periods of time.
Like all succulents, Euphorbia Lactea needs to be planted in quick-draining soil; just like the soil that it grows in its native environment.
Therefore, whether planting it in a container or in the ground, manufactured succulent or cactus soil should be used. Alternatively, you could make your own substrate by mixing together standard potting soil, perlite, and coarse sand.
Mottled spurge can be grown from seed or can be propagated from mature plants. However, do note that both methods can be difficult. The seeds can be hard to find and if you can locate them, germinating the seeds is often difficult.
Furthermore, growing from cuttings can also be challenging, as the plant produces a milky-white sap-like substance that can be toxic in nature to some people, as well as to animals.
With that said, if you would like to establish your own mottled spurge, your best bet would be to purchase an established plant and propagate it.
The best time to propagate is during the summer season, when the plant is actively growing. Because the plant does feature toxic latex sap that can be irritating when exposed to, make sure to take proper precautions and wear a pair of goggles and gloves before handling.
- Propagation should take place from a healthy root stock on the plant.
- Use a sharp, sterile knife to cut a “V” into the upper portion of the plant.
- Carefully trim off the stem of the succulent shrub where the stem connects to the branch. Once removed, use cold water to wash the sap away and then dip the cutting into commercially manufactured rooting hormone powder.
- Set the powder-covered cutting aside until the end callouses over; usually, this will take about a week.
- Once calloused-over, set the cutting so that it is in an upright position in well-draining soil; mist the surface of the cutting and wait until it takes root in the soil.
- To speed up rooting, set the cutting in a warm location, as roots establish more rapidly in warm settings. Generally, it takes a few weeks for rooting to be complete.
Whether you have purchased an established Euphorbia Lactea from nursery or you have propagated your own plant, it’s important to properly repot it.
Remember, this succulent can grow rather tall, so it needs space so that the roots can spread out.
Fill a container that features a drainage hole with pre-made succulent soil, or a substrate that you have mixed yourself. Thoroughly wet the soil and dig a hole in the center of it.
Carefully remove the succulent from its existing container. Remove as much soil from the base of the plant to expose the roots. Carefully inspect the roots to check for any damage or rot; remove any roots that appear to be problematic.
Set the base of the plant in the new container. Spread out the roots and cover them over with soil. Set the newly potted plant in a warm location that receives ample amounts of light.
In warm climates, Euphorbia Lactea can be planted outdoors and in the ground. If you are planting it in the ground, make sure to choose a location that receives partial sun to partial shade. Remember: the soil needs to be well-draining.
Carefully remove the plant from its pot. Gently wipe away as much soil from the base as possible to expose the roots. Check for any damaged or rotted roots and remove them. Set the plant into the ground and cover with soil.
Euphorbia Lactea Care
While mottled spurge is relatively easy to care for, it does require some degree of care. Here’s a look at some basic care tips.
Like all forms of succulents, Euphorbia Lactea should be watered using a “soak and dry” technique. In other words, wait until the soil is completely dry and then give it a good soaking. Excessive watering can cause root rot and can drown the plant. In the summer, it may require more watering, and in the winter, less. Keeping an eye on the soil is the best way to determine when to water.
Other than removing spend flowers (if your plant grows flowers), Dragon Bones Tree does not require any grooming.
Pests and Insects
The Dragon Bones Tree does attract some species of pests and insects. If you notice this problem, wetting the plant can help to remove any pests and insects that may be inhabiting it. Alternatively, you can apply an insecticide soak to the soil; however, do not apply insecticide to the branches or stems of the plant itself.
Summing It Up
Euphorbia Lactea makes a dramatic statement, whether planted indoors or out. By using proper planting and care tips, you can enjoy this succulent shrub for years to come.
