This charming cultivar differs from the standard Euphorbia abdelkuri in its pinkish-reddish body-color, varying in intensity with light levels.

Euphorbia abyssinica

euphorbia abyssinica

Euphorbia abyssinica is a nice large, cactus-like, candlestick, tree Euphorbia with short thorns. It forms a dense crown of ascending branches usually up to 4,5 m tall (but reported to reach 9 or more meters of height).

E. abyssinica is a highly variable species with several forms and making precise descriptions may be difficult.

Euphorbia actinoclada

euphorbia actinoclada

Euphorbia actinoclada is a dwarf spiny, perennial, succulent shrublet up to 50 cm in diameter and 15 cm tall, but usually smaller, with a fleshy root merging into a short thick rootstock (often called a caudex).

The upright branches are up to 15 cm long and 1 cm in diameter and spread in the upper part. Their surface is dark green with brighter longitudinal stripes. The flowers (cyathia) are reddish.

Euphorbia aeruginosa

euphorbia aeruginosa

Euphorbia aeruginosa is a very decorative spiny, succulent, forming dwarf, shrubs 15-30 cm in height (up to 40 cm recorded north of Punda Milia) and a subterranean caudex. Branches bluish-grey or brownish-green with many brownish spines. Branching occurs at or below ground level and above too.

Its name, which means ‘verdigris’, refers to the coppery-green branches which have contrasting reddish-brown spines.

Euphorbia aggregata

euphorbia aggregata

Euphorbia aggregata is a dwarf dioecious succulent shrub, very spiny and free-branching that forms a low tufted cushion-like mass composed of hundreds of heads that grows up to 1 m in diameter, but very old large plants with up to 40.000 (or even more) heads have been reported.

E. aggregata is closely related to Euphorbia ferox and Euphorbia pulvinata, which can be recognized by their striking growing shape. Therefore its more likely that intermediate forms between the mentioned species will occur in the habitat. The fierce peduncles that characterize Euphorbia ferox are few in number on this species.

Euphorbia albipollinifera

euphorbia albipollinifera

Euphorbia albipollinifera, named after its unusual pure white pollen, is one of the lesser-known medusoid type euphorbias, with a subglobose body, tuberculate, central apical area, and relatively few spreading branches up to 75 mm long.

Euphorbia alluaudii

euphorbia alluaudii

Euphorbia alluaudii (Cat Tails Euphorbia) is a dioecious (exceptionally monoecious) succulent shrub or small tree made up of clusters of cylindrical, jointed, spineless branches. Most of its branches rise erectly from the base and then arch outwards to form a mass as wide as tall.

It can ultimately reach 4(-6) meters though in containers it more commonly grows to a modest 1.2-1.8 meters tall. At the tips of the stems, small yellow flowers will appear in the spring and summer and the developing fruit is red and somewhat heartshaped.

Euphorbia ambovombensis

Euphorbia ammak is a striking Euphorbia of massive stature that resembles Euphorbia candelabra. It branches but not profusely. It is a typical representative of large, tree-like Euphorbias that can grow up to 10 m tall with a short trunk, it is superficially similar to some new world Cacti. The upright broadly obconical crown of this plant makes it looks like a branched candelabra.

Euphorbia ankarensis

euphorbia ankarensis

Euphorbia ankarensis, as is implied by the specific name, is a rare and localised species confined to the ‘Falaise d’Ankarana’ in NW Madagascar. It has short fleshy sticks with attractive pale green cones of cyathophylls at the top, followed by deciduous leaves which are shed at the beginning of the dry season.

Euphorbia antiquorum

euphorbia antiquorum

Euphorbia antiquorum is one of the largest armed tree Euphorbias, cactus-like in appearance with a rugged elegance growing up to a height of 5 – 7 m, branched and branched to form a loosely rounded crown, it has been known to attain gigantic proportions if left undisturbed, but usually shrub-like.

Euphorbia aphylla is a small, evergreen, densely branched and succulent shrub 30-80(-250) cm tall. The pencil-like shoots (apparently missing leaves) arise from a short trunk and branch further into whorls. The species name ‘aphylla’ comes from the Greek for ‘without leaves’.

Euphorbia arbuscula

euphorbia arbuscula

Euphorbia arbuscula is an impressive leafless shrub or broad-crowned candelabrum tree 3-7 m high that produces a white resinous exudate when cut. It is a succulent plant without real leaves, where photosynthesis is guaranteed by the green parts along with the tips of the branches.

The mature specimens are gorgeous trees that provide shade from the scorching sun, as the dense crown has no leaves to shed. Irregularities in the shape of the individual, especially aged, trees are due to traumatic events which change the vitality of one or more branches. The fruits are brown.

Euphorbia atrispina

euphorbia atrispina

Euphorbia atrispina is a dioecious ‘cushion’ euphorbia, branching densely from the base. Apart from the fact that the species is a dwarf (7-20 cm high), no important features distinguish it from its close allies, Euphorbia heptagona and Euphorbia enopla which have a larger, bushy habit.

These three spiny shrubs are difficult, if not impossible, to distinguish. Euphorbia atrispina is really beautiful, easy to grow and looks best in cultivation when young and goes on to produce large mounds with time.

Euphorbia balsamifera differs from other species of the genus by having a single-flowered terminal inflorescence. Also like other Euphorbia, it is unisexual, with male and female flowers on separate plants. It is pretty variable where leaf characters and stem development are concerned.

In summer it loses its leaves and reveals a bare tree trunk looking like death. In reality, it is not dead but it is a summer deciduous. In order to prevent the loss of water through their leaves in times of drought and high temperatures, the plants choose to lose them, even if it means stopping the photosynthesis process and entering into a rest phase.

Euphorbia gymnocalycioides

euphorbia gymnocalycioides

Euphorbia gymnocalycioides is a great-looking small succulent euphorbia with a deep green, knobby globoid body. It bears such a striking similarity to a genus in the cactus family, Gymnocalycium, that it was given the epithet “gymnocalycioides” (resembling Gymnocalycium).

This is a fine example of convergent evolution, a process in which the same adaptive traits evolve in distantly related species or groups as a response to similar environments (in this case, hot and dry deserts).

Euphorbia halipedicola

euphorbia halipedicola

Euphorbia halipedicola is another of the Euphorbia cooperi-like plants with some subtle differences. It is a rare succulent shrub or small candelabra tree up to 4 m high, usually with a single trunk crowned with a whorl of segmented branchlets.

The branches do not split again, unlike the common tree Euphorbia. Old dead branches hang underneath the compact crown for a while. Over time all lower branches shed in a continual process leaving the top branches to accentuate the candelabra form.

Euphorbia hamata

euphorbia hamata

Euphorbia hamata is a thornless low-growing succulent, bushily branched from the base, sometimes forming large dense twisted masses 30(-45) cm high and 45 cm in diameter with small green to reddish flowers at the growing points. It is dioecious (unisexual).

Euphorbia handiensis

euphorbia handiensis

Euphorbia handiensis is a small clumping, columnar cactus-like shrub up to 1 m tall with sparse, long white spines, branching near the ground and branching forming relatively large specimens with age. Euphorbia handiensis is recognized as one of the rarest euphorbias under cultivation today.

The inaccessibility and limited area of its habitat, together with the slow growth of seedlings will keep this species always among the rarer euphorbias.

Euphorbia heterochroma

euphorbia heterochroma

Euphorbia heterochroma is a small cactus-like spiny succulent shrub up to 2 m tall. The thin branched stems are attractively marked and may or may not have thorns. The species is very distinct from all those most nearly allied to it and easily recognized by its long-exerted small capsule.

Euphorbia hofstaetteri

euphorbia hofstaetteri

Euphorbia hofstaetteri is one of the thicker stemmed species belonging to the Euphorbia milii group. It is a remarkable shrubby Euphorbia to 70 cm tall, that has velvety leaves with a hint of a red margin.

The stems of this shrubby species are swollen at the base and are densely covered with spines. The flowers ( cyathia) are yellow-green with decumbent, red-brown striped, green cyathophylls (petal-like bracts).

This Euphorbia resembles Euphorbia croizatii, which comes from the extreme south between Ambovombe and Ifotaka, or Euphorbia rossii from the Mangoky river, which has a similar spination.

Euphorbia horombensis

euphorbia horombensis

Euphorbia horombensis is a laxly and irregularly branching, xerophytic shrub with a spiny succulent stalk of the Euphorbia milii group, 1 to 1.5 m high.

It is similar in growth habit to Euphorbia milii var. breoni but differs from it in the shape of the spines, which are flattened base, in the densely branched inflorescences and in the smaller, reddish-brown cyathophylls (specialized leaves that surround the cyathium and give an overall flower-like appearance to the whole).

Euphorbia horrida

euphorbia horrida

Euphorbia horrida is a spiny succulent shrub with irregular basally clumping stems. In age, it will form tight clumps of upright columns up to a meter wide that closely resemble some cactus species. It also has clustered crowns of somewhat ferocious spines much like the true cacti.

Euphorbia horwoodii

euphorbia horwoodii

Euphorbia horwoodii is really a nice looking dwarf fibrous-rooted succulent that in the juvenile stage forms a sphere with completely reduced branches and form compact side-arms later as it gets old. Mature plants about 5 cm high and 12 cm in diameter.

But rarely cultivated plants on a graft retain their incredibly compact, highly evolved habit and often become almost a thorn bush with long messy side branches up to 30 (or more) cm in diameter. There seem to be several quite different-looking clones known in cultivation.

Euphorbia inaequispina

euphorbia inaequispina

Euphorbia inaequispina is a dwarf and branching perennial succulent, leafless, and very spiny. The cylindrical stems, crowded shields, and long unequal spines, readily distinguish this from all other known species except Euphorbia ellenbeckii, from which it differs in the spine-shields not being 3-lobed, and an entire absence of a pair of prickles at the base of the spines.

Euphorbia inermis

euphorbia inermis

Euphorbia inermis is a many-branched medusa-form euphorbia up to about 50 cm in diameter with branches radiating like fingers from a central stem, continued below ground as a large fleshy tuber. Euphorbia inermis is monoecious.

A properly grown plant is a joy, especially when it is in flower, for then each short, erect finger is covered with fragrant, pure white (or yellow) flowers that look like snow crystals and the cluster is exquisite.

This is one of the caudex-forming Euphorbias, very similar to Euphorbia esculenta and Euphorbia caput-medusae. If you look down into a large specimen you’ll see what looks like a sunflower; it’s another example of a Fibonacci spiral. The whole plant produces a caustic milky sap.

Euphorbia infausta

Euphorbia ingens is very similar to Euphorbia candelabrum from the Horn of Africa and eastern Africa and may be conspecific. The branches of Euphorbia ingens are usually more distinctly and shortly segmented, the teeth along the angles are usually further apart and the branch tips bear fewer inflorescences.

Euphorbia itremensis

euphorbia itremensis

Euphorbia itremensis is a succulent geophyte plant that grows a subterranean napiform tuber producing several branches often strangely twisted and bent. In habitat, only the rosettes of leaves appear on the surface, but the pachycaul root can be deeply buried in the sand. Each rosette leaf corresponds to the apex of a stem.

The flowers of Euphorbia itremensis are said to be cream faintly tinged pinkish, but you can find anything from pure white to bright pink. The two-color forms coexist in the same habitat, and pale pink intermediate forms do occur.

Euphorbia lactea is one of the most common succulent euphorbias in cultivation, but highly variable with several forms and hybrids making precise descriptions of it difficult.

Variegated and crested Euphorbia lactea is a popular subject for grafting; prized specimens are intricately convoluted and blend creamy white with shades of green and pink.

Euphorbia lactea cv White Ghost

euphorbia lactea cv. white ghost

Euphorbia lactea cv White Ghost is a striking and very popular cultivar lacking in most of the chlorophyll-bearing tissues of its green counterpart. This Euphorbia doesn’t even look like a real plant and has an overall creamy white or greyish coloration.

Triangular stems grow in dense candelabra form with distinctive silhouettes and grow up to over 3 meters.

Very good in dry indoor situations, it is a much hardier plant than usually listed that does fine on its own roots. It and can also be grown outdoors in warmer climates even to full sun, though probably morning sun would be the most ideal situation.

It is a relatively slow grower, at least compared to the ‘regular’ form of Euphorbia lactea It is a beautiful plant that makes an incredible landscape plant.

Euphorbia lamarckii

euphorbia lamarckii

With a height of 0.8-2.5 meters, Euphorbia lamarckii is one of the largest Canarian spurges that form large shrubs or small trees with woody trunks. It belongs to the group of endemic shrub species.

It differs from other species by its pedunculated, umbelliform and usually compounds inflorescences, yellow-greenish in color and because the floral bracts fall off before the fruit ripens.

The yellowish-green floral bracts and narrow lanceolate leaves with rounded tips are very similar to the king Juba spurge (Euphorbia regis-jubae) that spread on the eastern islands, but their distributions do not overlap.

Euphorbia lambii

The deciduous leaves are ovate to sub-cordate, light green with neat brown veining and are shed at the beginning of the dry season. The top of the branches produces attractive brownish-green cones of petal-like cyathophylls (Coloured bracts around the cyathium).

Apparently, it blooms at the end of its growth cycle so that it loses its leaves. It is one of the nicest Madagascan Euphorbia, rarely found in specialized succulent collections.

Euphorbia meloformis

euphorbia meloformis

Euphorbia meloformis has round green and purple banded, spineless stems with 8 to 12 ribs. It occasionally offsets from the base. It is very similar in look to E. obesa, but with small yellow flowers on long peduncles which dry and persist on the plant after blooming.

Euphorbia planiceps

euphorbia planiceps

Euphorbia planiceps is a low, succulent shrublet developing from an underground caudex (thickened stem) that is a continuation of the tuberous main root, divided below into carrot-like or longer roots.

On the head and at the sides the there are a great number of branches that re-divide, forming a dense congested mat (up to 300 mm in diameter) which appears flat on the soil surface.

This ‘flat head’ is due to the continual contraction of the branches downwards, a feature that controls water loss in the arid areas in which it lives. Unlike the related species here it does not develop rhizomes.

The plant is spineless but the peduncles however persist for a year or longer and are 1.5-2.5 mm long. Its remarkable flowers (cyathia) possess at the outer edge of the glands 3-4, conspicuous, teeth-like processes commonly referred to as fingers.

Euphorbia razafindratsirae is a choice miniature in the E. milii group. It forms a dwarf shrublet with horizontally spreading branches with a surprisingly ample caudiciform base. The plant is a low grower with pencil-thick branches bearing tiny spines.

When in leaf, the foliage is oblong, with wavy margins and slightly pubescent. The chartreuse to reddish cyathia, similar to those of the related Euphorbia hoffstaeteri, are formed during winter dormancy when the plant is leafless.

In summer it is partly shrouded by the pubescent, undulate-margined leaves. The caudex will form underground but can be elevated above the soil. It gets quite thick, to about 5 cm in time.

Euphorbia Care Guide

The thorns on these plants are about 0.6 inches long on average, but they can get as big as 1.2 inches over time if you take good care. There are about 2,000 species of these plants and they come in a variety of forms and sizes. These plants can grow to be as large as trees in some forms and some of them can be grown indoors too.

Some Euphorbia plants produce flowers that don’t look conventional and those who are dealing with these plants must watch out for a milky sap that can sometimes be poisonous. Here’s a look at your Euphorbia care and propagation guide.


These plants need full sun, which means they need to get direct sunlight for at least six hours on a daily basis. They might need protection from the afternoon sun depending on how strong the sun in your region is.

You can identify this by looking for burns or yellow coloring when exposed to too much sun. But typically, they grow well when planted outdoors in a sunny spot.

If you plan to grow this plant indoors, you must place it near a window that gets lots of sunlight. People who take this route like to pick south-facing windows for this reason. That way the plant will get sunlight all day long. Alternatively, invest in a good grow light for succulents that can replace natural sunlight.


These plants grow actively from spring to the fall season and that is when it should get the right amount of water. The right amount in this case is just making sure that the top two inches of soil are never dry.

So, if you spot them in that condition you should water the plant. That usually happens once a week because these plants are pretty great about tolerating drought. That is because these plants are native to regions that are described as semi-arid and rocky.

Sometimes the soil dries up to the point that it starts to feel crispy. Ideally, you should not let it get there. Your worst-case scenario should still get the plant watered once every month.

The best time to water these plants is in the morning so that they have enough ammo to deal with the sun during the day. But in the winter season, you must change tactics and water the plant only when it looks like it is starting to wilt.

These plants are a type of succulent which means they don’t need too much water. But that also means that they need well-drained soil as succulents do.

You can mix it with sand and add a little bit of perlite to the mix. If you add perlite, make sure that your potting soil and regular sand are mixed 50-50. Failing that, any commercial succulent potting mix will also get the job done. (We review the best soil for succulents in pots here.)

euphorbia care


Depending on the species, you will need to follow separate feeding techniques. But generally speaking, a little bit of fertilizing is good for these plants. You can add a little bit of organic fertilizer or compost to a young plant so that it grows healthily.

But you want to make sure that the fertilizer you are using is in liquid form and diluted a little to weaken it. You must also make sure that the fertilizer must be added to the plant in its growth period between spring and fall. In the winter, the plant is dormant and does not need to be fed as much.

Check out our article on the best fertilizer for succulents to help you choose the right one.

If your Euphorbia is in a container, you will have to feed it some more fertilizer compared to the ones that are being grown out in the ground. And if you notice yellow leaves developing at the bottom, that’s a sign that you need to feed the plant some fertilizer.


These plants are fairly easy to grow and maintain. That applies to the climate it is grown in too. You will need to ensure that the air is at least 50 percent humid throughout the year. If you are growing it indoors, you will be relieved to know that it grows okay in dry rooms too.

If you are looking for its best-case scenario, the temperature must be 70-80 degrees Fahrenheit during the day and 55-65 degrees Fahrenheit at night.

Pests and Diseases

Not many animals bother these plants thanks to the sap and the spines. But that does not discourage spider mites and mealybugs. They are the most common pest to attack these plants. And if it’s not taken care of right away, the attack turns into an infestation very quickly.

Propagating Euphorbia

These plants can be propagated in two ways: seeds and stem cuttings.

It is difficult for the seeds to germinate quickly which is why this is the tougher
method of the two. But if you take this route, you can get commercial sand mix and mix it in the same amount with coarse sand and plant the seeds in it. If there is
enough warmth, you will see growth in a couple of weeks. Otherwise, it can take 2-6 months.
