How Do You Care For Euphorbia Robbiae?
Wood Spurge is a herbaceous, perennial, fast-growing evergreen shrub that blooms in the spring with a bright yellow/green flower.
It grows in an upright spherical mound to 12 to 20 inches tall and is bushy and compact. The plant is mildly stoloniferous (that is, it produces new plants through runners) and is commonly employed as a ground cover. To avoid overcrowding, space the plants 18 inches apart before planting.
Wood Spurge thrives in full sun to partial shade, dry to medium, loose, well-drained soils. The plant can perish if the soil becomes damp, especially in the winter.
If your site contains hot summer days, it enjoys afternoon shade, but if there is too much shade, the beautifully shaped clumps can open up. Wood Spurge grows well in poor soils, including rocky-sandy soils.
Euphorbia amygdaloides var. robbiae is one of the few plants that thrives in poor, dry soil in the shade, making it ideal for growing under large trees. It spreads through subterranean runners to make a low weed-smothering carpet.
From spring to early summer, it produces erect spikes of lime green blooms that contrast with the dark glossy foliage. It serves as an excellent year-round evergreen foil for other shade-loving plants. The Royal Horticultural Society has bestowed the renowned Award of Garden Merit upon it (AGM).
Euphorbia amygdaloides var. robbiae should be grown in well-drained soil in moderate to full shade. In the autumn, prune wilted flower stalks. As part of routine border maintenance, remove undesirable seedlings each spring.
How Do You Prune Euphorbia Robbiae?
Wood Spurge should be pruned in late winter just before growth begins. If left unpruned, it will form a tall clump, which will take on a pyramidal shape.
Pruning encourages it to grow more compactly, forming a low mound and branching out with smaller plants if given room to spread.
When pruning, be sure not to cut off too many of the suckers that bubble up from the base of the parent plant; leave them alone and they will grow into full-fledged plants. Pruning also promotes flowering.
How Do You Propagate Euphorbia Robbiae?
In the spring, division is the most effective method of propagating Euphorbia Robbiae. Gently lift the plant from the soil with a garden fork, and then divide the clumps into smaller sections by hand or with a sharp knife. Each division should be about 4 inches tall.
To encourage the prolific underground runners to form, water the plants daily for several weeks in early spring.
This ensures that the tubers contain enough food reserves for the plant’s growth, and it also allows them to start moving toward sunlight to form shoots.
Push back the runners with a stick or a finger if they are encroaching on another part of the plant’s root, and keep moist until they have established themselves.
Where Does Euphorbia Robbiae Grow?
The Wood Spurge (Euphorbia amygdaloides) is a tiny evergreen perennial endemic to forests in Europe, Turkey, and the Caucasus. It is a shade-loving plant that may grow up to 80cm tall and has green foliage grouped in rosettes on woody stalks.
It produces flowering bracts in hues of green in late spring and early summer, with tiny green-yellow flowers in the center. It thrives in dry shade, under trees, particularly in a wooded habitat.
It is a sucker, and if left unchecked, it can grow invasive. Like many Euphorbias, its stems contain a toxic sap that can cause skin irritation.
Euphorbia amygdaloides var. robbiae is a wild form of the species with dark green foliage and spikes of lime green flowering bracts in spring. This form performs admirably in the shade.
Is Euphorbia Robbiae Evergreen?
This Spurge is one of the best for use as a groundcover in milder winter climates. Plants grow an evergreen spreading mound of bright green, leathery leaves held on bronzy-red stalks. Late spring displays clusters of greenish-yellow bracts.
Spreads by underground stems to form a thick, impenetrable patch. Tolerates dry shade under trees. It may be a little too vigorous for general use in the perennial border, but it is a wonderful contender for problem areas. If desired, the plant can be pruned immediately after blooming.
How Do You Water Euphorbia Robbiae?
It is best to water only during periods of extended drought, and then sparingly. Water immediately after planting or when the moisture content is low.
Reduce watering during hot summer days or in winter, following an extended drought period. Do not allow the soil to become soggy or the plant will rot and die.
Keep the soil evenly moist, but never waterlogged. Water deeply and infrequently to encourage the roots to grow downward in search of moisture and nutrients.
How Do You Control Euphorbia Robbiae?
Cut back robbiae after flowering to prevent it from self-seeding; and, if it likes you too much (and it can), dig out the roots to prevent it from spreading. One final word of caution: when cut, members of the euphorbia family release a milky fluid that is both deadly and irritating to the skin.
The seeds (which resemble capers but are extremely deadly) are expelled explosively and distributed by ants (reference). We’ll have to be cautious when removing it because the toxic, milky sap can cause skin discomfort and perhaps significant injury if it gets into our eyes.
Because of the mat-like appearance of the spotted spurge weed, hand plucking is an effective method for eliminating it from the lawn or flower beds. Because of the unpleasant sap, wear gloves. Make sure to pull this plant before it develops seeds; otherwise, it will spread quickly.
Is Euphorbia Amygdaloides Var Robbiae An Indoor Plant?
Euphorbia Robbiae is perfect for growing indoors. It requires very little light, so you can even put it in a windowless corner of your house. It needs well-drained soil and a moderate amount of water, and it will quickly form an attractive ground cover.
What Is Euphorbia Amygdaloides Var Robbiae Good For?
Euphorbias are excellent for informal natural landscaping. They are very easy to care for and extremely adaptable. Euphorbias make an excellent addition to terrariums, rock gardens or containers. They make a very unique addition to the garden, but only in small amounts because they spread like crazy!
One of the best features of this spurge is that it is highly unusual and will draw attention. It is quite attractive, especially during the growing period, and will add a touch of interest to your yard or garden.
How Tall Does Euphorbia Amygdaloides Var Robbiae Grow?
This species can reach a height of 30 inches (76 centimeters) and 60-75 cm wide.
It grows to about 2 feet tall and 2 feet broad and spreads by suckers. At a reasonable and beneficial rate, rather than an alarming rate. Another feature it has with its relatives is a disdain for bogs. To keep it happy, give it any relatively well-drained soil.
Cut off the old flowers for cosmetic reasons, or if you’re as apathetic about flowers as I am, simply cut them off. You must decide whether they are a credit or a liability for yourself.
It has a great solid texture, grows well in shadow, spreads a little – but not too much – and is really dependable. The blooms, like other Euphorbias, are strange. Shrek’s ears are yellow/green.
Can I Cut Euphorbia Robbiae Down?
Cut flowering stems to the ground. This means that plants have two sorts of shoots: those from the previous season, on which the blooms develop, and those from this season.
Cut the flowered stems down to ground level in late summer or autumn so that the next season’s shoots can flower the following year.
It grows between 40 cm and 60cm tall, depending on whether or not there is other vegetation around it.
Is Euphorbia Amygdaloides Var Robbiae Easy To Care For?
This plant is great for beginners because it’s not very fussy. If you take it outside in the summer, it may get too much sun. So, either put it under a tree or provide shade. During the winter months, you can put your plant in front of a sunny window and let it grow while indoors.
Euphorbia Robbiae is easy to care for. It prefers well-drained soil, and it is a low-maintenance plant. In the wild, it can tolerate drought and poor soils, but in the garden, it is much happier planted in rich soil.
How Do You Tell A Euphorbia Robbiae?
Euphorbia amygdaloides, sometimes known as wood spurge, is a bushy, evergreen, compact, free-branching euphorbia that grows to 12-20″ tall in an erect circular mound. It is found in woodland borders throughout Europe, Western Asia, and the Mediterranean.
It has spatulate to obovate matte green leaves that are purple colored underside (up to 3″ long). Lower leaves alternate with upper leaves in whorls along the stems.
Throughout the summer, the leaves are bright green, but when the weather cools, they take on lovely purple-burgundy tones. Broken stems produce a white milky sap that can irritate the skin and is toxic if consumed.
In the spring (April to June in St. Louis), stems are topped by an inflorescence (to 8″ tall) bearing yellow-green blooms borne in cyathia.
True flowers lack sepals and petals and are unnoticeable (single pistillate flower is ringed by several staminate flowers). These blooms, however, are supported by long-lasting, yellow-green, leaf-like floral bracts that are extremely showy and contrast well with the plant foliage.
