Is Euphorbia Maculata Poisonous?

Is Euphorbia Maculata Poisonous?

When pinched or agitated, spotted spurge shoots exude a milky latex sap. Diterpene ester-type toxins found in Euphorbiaceae members contaminate animal feed and may cause dietary cancer in humans.

These chemicals are harmful enough in primary and secondary consumers to be classified as carcinogens (Cox et al. 2006).

When consumed, diterpene esters in the milky latex [of C. maculata] can produce nausea, vomiting, and diarrhea. After some time, redness, swelling, and blisters appear after contact with the skin and exposure to sunlight (Russell 1997).

The spurges (Euphorbia spp. or Chamaesyce spp.) have an acrid latex component in their milky sap. This sap is somewhat irritating to the skin, but it is also toxic and carcinogenic. Irritation is caused by exposure to the sun (Purdue 2007).

Toxic characteristics are present throughout the year and may play a role in allergies, hayfever, and/or asthma.

How do you take care of Euphorbia maculata?

Euphorbia maculata, often known as spotted spurge or prostrate spurge (not to be confused with Euphorbia prostrata), is a fast-growing annual plant native to North America in the Euphorbiaceae family. In the United States, it is a common garden and lawn weed.

It thrives in sunny spots and a wide range of soils, and it serves as a pioneer plant in ecological succession.

This plant’s sap is a moderate skin irritant that might give some people a rash. The sap is toxic and can cause cancer.

Euphorbia maculata is usually prostrate, with specimens seldom exceeding 30 centimetres in height (12 in).

The stems form a mat on the ground, with each stem rarely exceeding 45 cm (18 inches) in length.

The leaves are oval yet elongate, measuring up to 3 centimeters (1.2 in) in length and grouped in opposing pairs.

The cyathia, which are bisexual reproductive organs unique to the species, are tiny, with four white petal-like appendages that are occasionally pink.

The leaves often have a scarlet spot in the center, giving the plant its popular name of spotted spurge.

It looks like Euphorbia prostrata, although the latter has shorter leaves with more rounded tips.

It’s sometimes mistaken for Euphorbia serpens, but the relatively short and rounded leaves of E. serpens, together with the larger (but still inconspicuous) cyathia, should eliminate any confusion.

They do well in the following conditions

Soil requirements

The spotted spurge tolerates a wide range of soils and will grow in sandy, loamy, clayey or rocky conditions.

The soil can be acidic or alkaline. The soil should be well-drained, but this doesn’t mean that it has to be dry. In fact, its prostrate leaves can lead to leaf wetting by rain or irrigation. The plant needs full sun and a well-drained soil.

Spotted spurge is highly tolerant of drought, as well as moderately tolerant of salt and wind erosion

Water requirements

The spotted spurge plants are extremely drought-tolerant. They have been known to survive with one rainfall every 7–9 months under the correct conditions.

It grows best in moist soil but will tolerate drought conditions.

Light requirements

The spotted spurge is a fast-growing weed that grows well in full sun to partial shade but does best if allowed to grow in full sunlight. It may grow in shady areas but will be less vigorous there than it would be if growing in a sunny spot.

Temperature requirements

Despite the fact that it may sprout at temperatures as low as 60°F, spotted spurge isn’t a concern until temps rise beyond 75°F. While it is simple to kill, prevention and tenacity are essential for long-term management.

How do you grow Euphorbia maculata?

Spotted spurge prefers full sun, dry conditions, and sandy, gravelly, or rocky open barren land.

Prostrate spurge is a summer annual that thrives in dry, sandy soil, low-nutrient soil, and compacted to disturbed environments.

Because C. maculata is an annual plant that thrives in arid environments, it is unlikely to disrupt water flow. Water flow is unaffected or little affected.

Because C. maculata is an annual plant that thrives in arid environments, it is unlikely to have an impact on water quality.

Is Euphorbia maculata a succulent?

Spotted spurge is a prostrate-growing summer annual weed that thrives in warm regions and fades back after frost.

It can be found in cracks in sidewalks, gravel, roadsides, gardens, and even woodlands.

The small, oblong leaves have an uneven red to purple mark in the center and grow opposite on the stalk. When the stems are damaged or injured, a milky white sap is released, comparable to that of dandelion.

The plant has a strong taproot that can reach two feet into the earth and roots at the leaf nodes only seldom or never.

Summer and early fall provide the little greenish-white blossoms. Even tiny seedlings with little or no dormancy can blossom and set a large number of seeds.

Spurge populations can quickly grow since they blossom young and have little or no seed dormancy.

Remove plants as soon as possible to decrease seed production; however, due to the large number of seedlings that grow, hand weeding can be time-consuming.

Because plants grow so close to the earth, mowing is futile. Most preemergence herbicides are effective at controlling spurges.

Spotted spurge, commonly known as Prostrate Spurge, is closely related to Euphorbia prostrata.

Euphorbia prostrata has shorter leaves that are more rounded at the tips and no spot in the center, making it easy to identify between them.

Is Euphorbia maculata an indoor plant?

The prostrate summer annual spotted spurge is native to the United States. This plant, also known as spotted sand mat, can be found in sidewalk cracks, roadsides, gardens, and thinning or drought-stressed lawns.

To germinate, it only needs heat, light, water, and a small amount of soil, albeit it is not particularly competitive in good growing circumstances.

Spotted spurge can signal an underlying issue, such as soil compaction or drought stress.

This weed prefers warm, constant air temperatures above 75°F, so you won’t see it in the spring.

Individual plants develop outward from a central growth point above a taproot, typically flat against the soil surface.

At the nodes, the stems do not root. When stems are broken or wounded, a milky white sap is released, which is irritating to the eyes and skin. Sheep are also poisoned by spotted spurge.

How do you control prostrate spurge?

Herbicides, both pre- and post-emergence, can be used to control prostrate spurge.

Preemergence control can be performed by applying isoxaben (Gallery, Isoxaben) in the spring before germination in the summer.

Dinitroaniline herbicides (such as Barricade and Pendulum) can also be used to suppress prostrate spurge, albeit the effects are less reliable than isoxaben.

Once spurge has germinated, cool-season grass can be controlled with two- or three-way mixes of 2,4-D, dicamba, MCPP, or MCPA, which are available in a variety of formulations at local stores. Due to the development of new seedlings, more treatments may be required.

Is Spotted spurge a weed?

Spotted spurge (Euphorbia maculata), a spotted plant that flourishes in the heat of summer, is an ugly nuisance that not only takes up home in weak sections of the grass, but also invades landscaping beds, sidewalk cracks, and vegetable gardens.

The hairy red stems that branch out from a central point, small dark green leaves with a red spot, and thick, mat-like form distinguish Spotted spurge.

This annual weed emerges in mid-spring and blooms throughout summer with inconspicuous, small green flowers.

Spotted spurge may be differentiated from other weeds by the milky sap that is generated when any portion of the plant is injured, in addition to its trademark red dots.

It may produce a thick mat up to 3 feet broad in thin places of the lawn.

Is Euphorbia maculata edible?

Euphorbia maculata is a prostrate-growing summer annual weed that thrives in warm regions and fades back after frost.

It can be found in cracks in sidewalks, gravel, roadsides, gardens, and even woodlands.

The small, roundish to oval-shaped leaves have an uneven red to purple spot in the center and grow opposite on the stalk.

When the stems are damaged or injured, a milky white sap is released which is irritating to the eyes and skin.

The sap is poisonous and considered carcinogenic. They are not edible

Will roundup for lawns kill spotted spurge?

Herbicides can also be used, however many of them are only effective against spurge while the plants are young.

Once mature, they can withstand a wide range of weed killers. Herbicides for killing spurge are most effective when used in late spring or early summer, when spotted spurge first sprouts.

Glyphosate is one of the few herbicides that will operate on adult spurge (Round-Up).

However, be cautious since glyphosate can destroy whatever it comes into touch with. Even with this, the spurge may sprout from the roots, so keep an eye out for it and treat it as quickly as possible if you detect it.

Pre-emergent sprays or granules can also be used to suppress spurge, but only before the seeds have sprouted.

Is Euphorbia maculata a fast grower?

These low-growing plants mature slowly and are frequently overlooked until late summer. Frost annihilates plants.

The ovate, somewhat hairy dark green leaves grow in opposing pairs on pink to maroon hairy stalks.

The leaves are frequently marked with a red spot in the center of the top leaf surface, however this marking is not always present.

The stems radiate from a central node and do not root at the nodes. When damaged, they produce a milky sap (a hallmark of the euphorbia family).

The sap irritates the skin of those who are sensitive to it and is particularly poisonous to sheep.

How to Euphorbia maculata propagate?

Euphorbia maculata propagate through seed.

The majority of weedy spurges are summer annuals that dislike competition and rely on their prodigious seed output to survive.

A single plant can develop thousands of tiny seeds that can remain dormant in the soil until the conditions are favorable for germination (sprouting).

Summer seeds grow instantly, but late fall seeds are generally dormant and will not germinate until spring.

Spotted spurge germinates best at temperatures ranging from 75° to 85°F, although it can germinate at temperatures as low as 60°F and as high as 100°F.

Germination may occur in most parts of California from February to September if moisture is present.

Light is also necessary for optimum germination; seeds buried more than 1/2 inch will not germinate properly.

Plants that germinate in chilly circumstances early in the spring might persist as little seedlings until temperatures warm up enough for development.

When the seed germinates, it produces a tiny rosette of leaves. As the plant grows, the leaves produce a thick mat that can reach 3 feet in diameter.

The plant’s reproductive development is quick, and it can generate seeds as early as 5 weeks after germination.

Is Euphorbia maculata invasive?

As an adaptive annual species, spotted spurge has a high potential to spread.

In Europe and Asia, spotted spurge has been known to spread with the aid of flowing water and become a nuisance in irrigation systems as well as small ditches.

If the weed escapes cultivation, it is capable of invading grasslands, pastures, fields, and open areas. It will form dense mats that reduce or eliminate native plant diversity.

Research has demonstrated that the weed can also invade wetland areas, marshes, and even catchments.

In California, spotted spurge is considered to be a noxious species and is on the California Invasive Plant List of Pest Plant Species section of the Integrated Pest Management Policy Manual.
