Euphorbia pseudoglobosa

Botanical Name — Euphorbia pseudoglobosa

Common Name — False Globose Spurge

Plant Family — Euphorbiaceae

Background

Originating in South Africa, Euphorbia pseudoglobosa is a striking dwarf succulent with knobby, blob-like leaves sometimes tipped with tiny yellow-green flowers. With maturity it develops a pronounced caudex, or bulbous root system, that many collectors like to feature by leaving a portion exposed above the soil. Spineless and alien, this plant makes for a unique addition to the collection.

Growth Requirements

Sun

Euphorbia pseudoglobosa does best in full sun, at least 5 to 8 hours a day. Avoid intense afternoon sun. Grow outdoors in light shade or indoors in a sunny window with southern exposure and direct sun.

Temperature/ Humidity

Euphorbia pseudoglobosa prefers warm temperatures in the 70s and 80s. It can become stressed if left in conditions of extreme temperatures or intense sun.
These plants are not cold hardy, if grown outdoors migrate these plants to a sunny spot indoors when night time temperatures drop below 55 ºF.

Water

Native to arid and sub-tropical climates Euphorbia pseudoglobosa are drought tolerant plants. Water sparingly in the summer and only a few times throughout the winter. Their soil should be allowed to dry out entirely before watering thoroughly.

Soil/Roots

These plants prefer a sandy, sharply draining mix. Cacti or succulent potting mix is great. You can amend a regular potting soil with sand or pumice up to 50% to improve grittiness and drainage.

Flowering

These plants produce small yellow-green flowers during the spring and summer time. Potted plants and plants grown indoors may not flower.

Fertilization

These plants do not require fertilizer though it can be added to give container grown plants a boost or to supplement poor soil. Apply a water-soluble, balanced fertilizer monthly, diluted at half strength.

Propagation

Euphorbia pseudoglobosa can be propagated from stem cuttings. Take great care when cutting these plants as they contain a sap that can be highly irritant if contacted with skin.
Allow cuttings to callous for several days before dusting with rooting hormone and placing in soil.

Health

Diseases

Euphorbia pseudoglobosa are not prone to pests. Though not super common, they are more likely to fall victim to bacterial or fungal infections. Affected plants may need to be destroyed to prevent the spread of disease to other nearby plants.
Root rot can also be a concern and is triggered by overwatering. Always err on the side of underwatering.

Maintenance (pruning, legginess, repotting)

Little maintenance is required to grow these plants.
The deep, bulbous roots of this plant often require a deep pot, but once planted, they will be happy in the same pot for several years. Repot once every two to three years.

Toxicity

All Euphorbia plants contain a poisonous sap that is very toxic if ingested and highly irritant if contacted with skin. Keep out of reach of pets and children. Wear gloves and take great care when handling this plant.
