The most common common name for Euphorbia epithymoides is cushion spurge. Cushion spurge contains a toxic white latex sap that can cause irritation when it comes in contact with skin, mucous membranes, or the eyes. If ingested, this sap can cause symptoms such as nausea, vomiting, and diarrhea. In severe cases, ingesting the plant can lead to more serious symptoms, including weakness, lethargy, and in some cases, seizures or coma. It is important to avoid consuming any part of the cushion spurge and to wash hands thoroughly after handling the plant to prevent accidental ingestion or contact with the eyes and mouth.
To pets
Cushion spurge is toxic to pets due to the presence of a milky latex sap found throughout the plant. If a pet ingests any part of the cushion spurge, they may experience symptoms such as vomiting, diarrhea, drooling, and abdominal pain. In severe cases, ingestion can cause more serious signs like tremors or seizures. It is important to keep pets away from this plant and to seek veterinary care immediately if you suspect your pet has ingested any part of the cushion spurge.

WaterCushion spurge should be watered deeply whenever the top inch of soil feels dry to the touch, which might be roughly once a week, depending on environmental conditions. Irrigate with about 1 gallon of water per plant to ensure the soil is moistened well, but be careful not to overwater as this plant prefers drier conditions. During the growing season in spring and early summer, water needs may increase, but reduce watering in the fall and virtually eliminate it in the winter when the plant is dormant.
LightCushion spurge thrives in full sun to partial shade. It is best to place it in a spot where it can enjoy at least six hours of direct sunlight daily. Dappled shade during the hottest part of the day can help prevent scorching in regions with intense summer sun.
TemperatureCushion spurge is hardy and can tolerate a range of temperatures, withstanding minimum winter temperatures down to -30 degrees Fahrenheit. It performs best when the temperatures are between 60 and 75 degrees Fahrenheit, which are ideal conditions for growth. Excessive heat can be tolerated especially if there is adequate watering, but generally, extreme temperature fluctuations should be avoided.
PruningPrune cushion spurge to remove spent flowers and control its shape; this is best done in early summer after the plant has flowered. It can also be cut back in late fall or early winter to tidy up the plant and promote bushier growth for the following season. Pruning every year or every other year is generally enough to keep cushion spurge healthy.
CleaningAs needed
SoilCushion spurge thrives best in a well-draining soil mix with some organic matter. Ideal soil pH for this plant is slightly acidic to neutral, ranging from 6.0 to 7.0. A mixture of loam, sand, and compost in equal parts with a bit of peat moss can promote healthy growth and drainage.
RepottingCushion spurge does not need frequent repotting; it can be repotted every 2-3 years. It's quite adaptable but should be repotted if it outgrows its container or the soil becomes compacted.
Humidity & MistingCushion spurge prefers average room humidity levels; it does not require high humidity. Consistent moisture without waterlogging suits it best, avoiding too much dry air or excessively damp conditions.
Suitable locationsIndoor
Provide bright light, well-draining soil, and moderate watering.
Outdoor
Plant in full sun to partial shade, in well-draining soil.

Life cycleEuphorbia epithymoides, commonly known as Cushion Spurge, begins its life cycle as a seed that germinates in the spring when soil temperatures warm. The seedling quickly grows into a herbaceous perennial plant, forming a compact, bushy mound with light green leaves. By mid to late spring, Euphorbia epithymoides blooms, producing clusters of bright yellow-green flower bracts that stand out in the garden. After flowering, the plant may go dormant in summer if temperatures are too high or conditions too dry. In autumn, the foliage often takes on a red or purple tinge before the plant retreats into dormancy for the winter. Each year, the plant re-emerges from its rootstock in spring, repeating its growth and reproductive cycle.
PropogationPropogation time
Spring
The Euphorbia epithymoides, commonly known as Cushion Spurge, is commonly propagated by seed or division. However, the most popular method is division, which is ideally done in early spring or fall. This involves carefully digging up the plant and dividing it into smaller sections. Each section should have at least a few shoots and a portion of the root system. Replant the divisions immediately at the same depth they were previously growing, spacing them about 12 inches (approximately 30 centimeters) apart to allow for growth. Water the new plantings thoroughly to help establish them. This clump-forming perennial responds well to division and it helps to revitalize older plants that might be losing their vigor.
