A fascinating succulent with an almost surreal appearance
Prized for its geometric shapes and striking variegation, Euphorbia lactea native to tropical regions of Asia, has become a must-have for succulent collectors due to its adaptability and numerous varieties.
In this article, we’ll explore everything you need to know about Euphorbia lactea, from its cultivation needs to intriguing facts, with a special focus on three unique varieties: the ‘White Ghost’, the variegata, and the crested variegata.
Characteristics of Euphorbia lactea
Euphorbia lactea is a shrubby or columnar succulent, characterized by:
- Branched stems with well-defined ribs and short spines.
- Variegated colors, ranging from green to creamy white, and even pink in some varieties.
- White latex (from which it gets its name lactea, meaning “milky”), a toxic sap that oozes when cut.
- Upright growth, though some mutant forms develop spectacular crests or spirals.
- In the wild, this plant can reach 6-10 feet (2-3 meters), but in pots, it remains more compact.
Growing and caring for Euphorbia lactea
Soil
Prefers a well-draining mix, ideal for succulents. A recommended blend:
- 50% cactus soil
- 30% perlite or pumice
- 20% coarse sand
Avoid compact soils to prevent root rot.
Watering
- Summer: water moderately only when the soil is completely dry.
- Winter: reduce watering significantly (once a month at most).
Avoid waterlogging, which can cause root rot!
Light
- Bright, indirect light, with a few hours of direct morning sun.
- Tolerates full sun, but variegated varieties (like ‘White Ghost’) may scorch under intense rays.
- Minimum temperature: Not below 50°F (10°C)—it’s a tropical plant sensitive to frost.
Fertilization
Use a diluted cactus fertilizer once a month in spring and summer.
Euphorbia lactea flowers
Unlike many succulents, Euphorbia lactea rarely blooms in cultivation. When it does, it produces small yellow-green flowers (cyathia) similar to other Euphorbiaceae. Flowering is more likely in mature, well-cared-for specimens.
Three special Euphorbia lactea varieties
Euphorbia lactea ‘White Ghost’
- Features: Lacks chlorophyll, displaying an eerie creamy-white hue (hence its “ghostly” name).
- Care: Needs filtered light to avoid burns and grows slower than green varieties.
Euphorbia lactea variegata
- Features: Yellow, pink, or white streaks along the stems.
- Care: Similar to the standard form but more sensitive to strong sun.
Euphorbia lactea variegata cristata
- Features: Fan-shaped or crested growth with colorful variegation.
- Care: Requires less water than normal forms and must be protected from excess moisture.
Fun facts and symbolism
- Toxicity: the latex irritates skin and eyes—wear gloves when handling.
- Symbolism: in some cultures, it’s considered a good luck charm and a symbol of resilience.
- Monstrose & crested forms: genetic mutations make it a highly sought-after collector’s plant.
