Euphorbia Lactea 'White Ghost'
The Euphorbia lactea 'White Ghost' is an architectural masterpiece that looks like it was sculpted from pale marble. Often mistaken for a cactus due to its thick, spiny stems and candelabra-like branching structure, it is actually a striking succulent native to tropical Asia. What makes this specific cultivar so incredibly sought-after is its profound lack of chlorophyll. Instead of green, its stems are entirely creamy white, pale gray, and sometimes faintly flushed with pink when exposed to bright light.
Because it lacks the green pigment necessary to photosynthesize efficiently, the 'White Ghost' is a famously slow grower. This makes large, branching specimens highly prized collector's items. It is the ultimate statement plant for minimalist, modern, or desert-inspired interiors, requiring very little water and practically zero maintenance to maintain its stunning, ethereal silhouette.
Light
▾
Bright, indirect light is absolutely essential for the 'White Ghost'. A location near an east or south-facing window where it receives plenty of ambient brightness and perhaps a few hours of gentle morning sun is perfect. Too much shade will cause its extremely slow growth to stall completely, while harsh, direct afternoon sun will cause severe sunburn on its delicate white stems.
Watering
▾
Treat this plant exactly like a cactus. Allow the potting mix to dry out 100% from top to bottom before you even consider watering it. When you do water, soak it thoroughly until water drains freely from the bottom, then empty the saucer immediately. In the heat of summer, this might mean watering once every 2 to 3 weeks. In the winter, you can often withhold water for a month or more. Overwatering is the single easiest way to kill it.
Humidity
▾
This succulent prefers a dry, arid environment. Average indoor household humidity is perfectly fine. Do not mist this plant, and ensure it has good air circulation. High humidity combined with stagnant air can invite fungal infections or stem rot.
Growing Media
▾
An extremely gritty, fast-draining cactus and succulent mix is absolutely mandatory. The roots are very fine and rot easily if left sitting in heavy, wet soil. Use a mix that is at least 50% inorganic material, such as coarse pumice, perlite, or horticultural sand. A heavy terracotta pot is highly recommended—not only does the porous clay help the soil dry out faster, but it also provides a stable base for the top-heavy branches.
Feeding
▾
Because it lacks chlorophyll, it processes energy incredibly slowly. It requires very little fertilizer. Feed it just once or twice during the entire spring and summer growing season with a specialized cactus/succulent fertilizer diluted to half-strength. Do not feed it at all during the autumn and winter.
Mushy, Brown, or Black Base
▾
This is stem rot caused by overwatering or soil that stays wet for too long. Unfortunately, once the base turns to mush, the root system is dead. Your only option to save the plant is to take a sterilized knife, cut the stem well above the rotting area (wear gloves to avoid the sap!), let the cut end callous over for a week in a dry spot, and then replant the cutting in completely dry, gritty soil to root.
Brown, Crispy Patches on the Stems
▾
This is sunburn. The white stems have no chlorophyll to protect them from intense UV rays. If the plant is sitting in a south or west-facing window taking the brunt of the hot afternoon sun, move it back a few feet or add a sheer curtain to filter the light. The burnt patches will not heal, but moving it will prevent further damage.
Dropping Tiny Leaves
▾
Don't panic! While primarily a leafless stem-succulent, the Euphorbia lactea will occasionally produce tiny, teardrop-shaped leaves on its newest growth points during the peak of summer. These leaves are vestigial and naturally dry up and fall off very quickly. It is completely normal behavior.
