How To Grow Euphorbia From Seeds

The most beautiful euphorbias are those like Euphorbia oblongata. bright lime green bracts, brilliant yellow blooms, and dark green, oval-shaped leaves with light green veins. Once in full development, the stems can be clipped for flower arrangements or left to give the flower bed a beautiful acid hue. This wonderful and gorgeous plant is one among the longest-flowering and most expensive of commercial cut flowers since the blossoms are produced from early spring through early winter.

Even though this plant only has a limited lifespan, it is frequently planted as an annual. Euphorbia oblongata has a lovely branching habit and is equally useful in the border and cutting garden. The freely broad flower heads have an enlivening brightness. Their acid-green bracts blend in well with just about any nearby plant.

Euphorbia oblongata, which reaches a height of about 50 to 60 cm (20 to 24 in), thrives in moist but well-draining soil in dappled shade with a few hours each day of direct sunlight.

Before planting, soak the seeds in warm water for two hours. Because euphorbia plants don’t like their roots disturbed, it’s preferable to plant the seeds directly where they will grow or to use deep plugs or pots. Grow between 20 and 26C (68 and 78F). Be patient; germination often happens very slowly. It may take two to three weeks, but it occasionally can take many months.

Seeding Straight:

Once the soil has warmed and the temperatures have risen, sow the seeds immediately where they will grow. Spread seeds over the soil’s top and keep damp but not soggy.

Planting inside:

Use a good seed sowing mix or well-drained soil to surface sow the seeds into plugs or small pots. Cover the seeds with vermiculite, but don’t block the light.

When a seedling is big enough to handle, prick it out and transplant it into a larger pot so it can continue to grow. Before planting, gradually acclimate for 10 to 15 days to outside conditions. Plant in sun and regular, well-drained soil at a distance of 30 cm (12 in).


Euphorbia require a soil mixture with good drainage and full sun to partial shade. Water the plants thoroughly and let them dry completely before watering them once again. The plants may grow naturally on rocky soils and don’t require a lot of water or fertilizer. Both can be overused and will result in lush growth at the expense of blooms. In the late summer or early fall, prune blooming stems back to the ground.

Fresh Flowers:

Cut flower ends can be seared over a flame or submerged in boiling water to prolong their vase life.

Uses of plants


Plants should be handled carefully when working with spurges, especially if sap is visible. Always wear gloves because the milky sap could irritate your skin and is harmful. The latex is damaging to the skin and can result in rashes or burns.


The spurge species Euphorbia oblongata is native to Eurasia but has been introduced to other parts of the world.

One of the most fascinating and varied genera is euphorbias, with over 2,000 species that are incredibly diversified and include many useful garden plants. The plant is a member of the Euphorbia pulcherrima family, which also includes poinsettias.


The plant was given the name Euphorbes in honor of Euphorbes, the royal physician of the Numidian king Juba II, who is credited with discovering the plant’s milky white sap’s potential for both poisoning and healing. The Greek words eu, which means “good,” and phorbe, which means “pasture or fodder,” combine to form the English term euphorbus, which has the meaning “well fed.”

The oblongata species name and the popular names oblong or eggleaf spurge only describe the shape of the leaves. The term “spurge” is a frequent name for euphorbias.

As the sap of herbaceous euphorbias was sometimes employed as a purgative and a laxative, the popular name “Spurge” comes from the old French word espurgier, which means “to purge.”

The Greek physician who treated Mauretania’s King Juba II, who was named Euphorbus, inspired the name Euphorbia.

He wrote about an African plant that resembled a cactus and was employed as a potent laxative on the slopes of Mount Atlas, showing that he was evidently interested in botany. That plant may have been Euphorbia resinifera, which had a latexy exudate like all Euphorbias.

In Rome, Antonius Musa, the brother of Euphorbus, served as Augustus Caesar’s physician. Juba made the decision to honor his own physician by naming the plant he had written about after him after learning that Caesar had honored his doctor with a statue.

The Greek words eu, which means “good,” and phorbe, which means “pasture or fodder,” combine to form the English term euphorbus, which has the meaning “well fed.” According to some versions, Juba was amused by the wordplay and named the plant after his physician because of its succulent qualities and Euphorbus’ stout build.

How long does it take for euphorbia seeds to sprout?

10-14 days at 65-75F are required for germination (18-24C). Germination can occur randomly. In a greenhouse, seed should be sown and cultivated at 60F. (16C).

Plant three to four further sowings spaced two weeks apart for a continuous summer crop. Direct seed (recommended): Plant 1/4 of the seed after the last frost “deep. Transplant: Directly sow into cell packs or bigger containers 4–6 weeks prior to the final frost. Include seed. After the last frost, harden off and transplant outside.

Average, well-drained soil is ideal, but plants can grow in less-than-ideal soil. VEGETATION SPACE: 6–9 “.

Fresh stems should be cut when bracts are completely colored but before the blooms have opened.

Euphorbias are they simple to grow from seed?

There is also a less formal name for euphorbia plants (Euphorbia spp.) called spurge. They belong to a family of plants that can occasionally be grown outside or indoors. Euphorbia plants come in a wide range of variations, with unique shapes like shrubs, herbs, or examples that resemble cacti. It’s simple to grow euphorbias, and certain varieties may withstand cold conditions. These are simple to grow from seed and spread via cuttings. Find out how to grow a Euphorbia plant that will spark discussion and draw attention.

How to grow

Cushion For their seeds to sprout, spurge needs sunshine. The flower seeds should not be covered when the seeds are sown on the ground. Six to eight weeks prior to the end of the frost season, euphorbia seeds can be started indoors and then transplanted outside. Alternately, the seeds can be planted immediately outside in a prepared seedbed once the soil temperatures have warmed. The flower seed should be kept wet but not soaked.

After flowering is complete, prune the plant by roughly a third as part of its upkeep. The plant will remain tidy and compact after this pruning. Cutting the plant back can delay the self-seeding of Cushion Spurge, which is an easy operation. When touching the plant, use gloves since the white sap irritates the skin. Avoid overfertilizing plants since they will become leggy.

  • 3 seeds per plant, or 300 seeds, will cover around 10 square feet, is the recommended sowing rate.
  • 28 to 56 days on average for germs
  • attracts butterflies and bees
  • Surface sow, but firmly press seed into the ground.

Flower Specifications

The plant will thrive in full sun in temperate climates, but in southern climates, it will thrive more with some afternoon shade. Euphorbia Cushion Spurge should not be grown in moist or overfertilized soils. Although it can withstand severe drought, it struggles with foot traffic.

Euphorbia: Is it difficult to grow?

Euphorbias require relatively little maintenance. These plants need some care to get started, but once they do, they are remarkably self-sufficient. In actuality, more people perish from over care, particularly overwatering, than from neglect. However, they are tough and make excellent starting plants.

How quickly does Euphorbia expand?

The heavier stems have a tendency to point in the direction of the light as they grow. To stop the container from leaning, rotate it.

The shedding of leaves is typical. In a few months, fresh leaves will emerge at the top of the stem.

I can get up to 30 feet tall in nature. I can grow quickly indoors in a container and reach a height of 5-8 feet. From the base, fresh, light-green shoots will emerge.

You may have overwatered if you notice rotting at the plant’s base or notice that the stems are no longer spongey. By removing the top treatment and allowing the soil to breathe, you might attempt to dry it out. If the stem is still too wet, you can cut it with a fresh corrugated knife and transplant it in fresh, drier soil.

Can Euphorbia be rooted in water?

A succulent euphorbia called Euphorbia trigona is grown for its ornamental stems. If it is rooted in water, it will rot and should not be. Take a stem cutting of this plant in late spring or early summer to propagate it.

When taking cuttings, keep your skin and eyes protected because the sap might irritate some people’s skin or eyes or perhaps create an allergic response. The health of the parent plant and the cutting depends on stopping the flow of milky sap. Spray water onto the parent’s wound after dipping the cutting end in water. To prevent infection, allow the cutting to “heal” (dry out) for a few days. Create a container with a peat moss base that has been wet, add perlite for enhanced drainage, and then top it with a layer of horticultural sand or vermiculite to avoid rot. Place your cutting in the potting mixture and keep it at room temperature in filtered light.

For around two months, keep the potting material just slightly damp. By that time, the cutting will have developed roots and new growth. The plant can be replanted in a succulent potting mix and cared for as an adult euphorbia.

Which kind of soil are best for euphorbia?

Soil: Light, open, moist but well-drained soil (chalk, sand or loam). Any pH. Avoid being in a wet environment. Conditions: Optimal solar exposure.

Are euphorbias contagious?

The ideal plant for growing beneath large trees is Euphorbia amygdaloides var. robbiae, one of the few species that grows in poor, dry soil in shadow. It grows through subterranean runners and finally forms a low carpet that smothers weeds. From spring to early summer, it produces erect spikes of lime green blooms in contrast to the dark glossy leaves. It serves as a good evergreen foil all year long for other shade-loving plants. It has received The Royal Horticultural Society’s esteemed Award of Garden Merit (AGM).

Grow Euphorbia amygdaloides var. robbiae in partially to completely shaded, well-drained soil. Trim back fading flower stems in the fall. Every spring, as part of routine border maintenance, remove undesirable seedlings.

Wear gloves whenever handling euphorbias. The creamy sap irritates the skin.

Euphorbia Care:

Some plants need to be divided or propagated every two to three years, preferably in the early fall or spring, even if they have a short lifespan.

After flowering is complete, many benefit from being severely pruned, at least by one-third. This prevents any free-seeders from taking over and promotes the growth of new, fresh foliage.

Trimming euphorbia:

  • Early in the spring, remove any damaged stems to keep the plant neat and healthy.
  • As soon as the euphorbia blooms, trim the stems at the base.
  • Clip carefully, since new shoots may appear that you wish to preserve.

anything touches your skin because it is a potent irritant. Additionally harmful due to the sap, spurges should be avoided.

euphorbias and yard cats survive for years without trouble, but I don’t have kids or pets.


Check individual entries as perennial euphorbias have varying hardiness, especially in regards to their northern boundaries.

for the plants that are listed here. Some species only have root hardiness further north but are evergreen in southerly zones. Other varieties do well as annuals.

Exposure: Sun or Shade?

Although some euphorbias can take some partial shade, most euphorbias prefer the sun. those with dark purple or reddish coloring

If planted in full sun, the foliage’s coloration will be more dramatic. In fact, just a few species prefer at least dappled.

Others require part shade in the South’s blazing sunshine but can tolerate intense sun in the North, where they can thrive. One option that works well in shadow is Euphorbia amygdaloides var. robbiae.


The ability of spurges to withstand drought is one of its greatest advantages, hence proper drainage is essential.

The “Chameleon” does like more wetness than other animals. Euphorbias are also not fussy about soil, and the majority can

tackle common and sandy circumstances. Fertile soils may promote those varieties that tend to run and spread.

Keeping things lean gives control since people tend to expand beyond their limitations. However, if you want your
