Introducing the stunning White Ghost Cactus, also known as Euphorbia lactea variegata, a vibrant cultivar of Euphorbia lactea. While Euphorbia lactea White Ghost is commonly referred to as the "White Ghost Cactus," it's actually not a true cactus. It's a succulent shrub or a small tree from the Euphorbiaceae family.
The name "White Ghost" is given to it because of its pale white color and ghostly appearance. So, even though it's not a cactus, it's still called a "cactus" because of its cactus-like shape and the way it's often grouped with other succulent cacti.
With the thick, fleshy, triangular stems of the white ghost cacti, Euphorbia grows upright and branches out as it matures. The stems are variegated with shades of white, green, and sometimes even pink or yellow.
Instead of leaves, it has small, spiky thorns or spines along the edges of its stems. These thorns are not only decorative but also serve as a defense mechanism against predators.
Native to the tropical regions of Africa and Asia, with a slow growth rate, the Euphorbia lactea White Ghost cactus can grow up to 6 feet tall in its natural habitat. However, when grown as a houseplant, it tends to stay smaller, usually reaching heights of about 1 to 3 feet. Its size can also be controlled through pruning and proper care.
The flowers of the white ghost cacti bloom in the spring season with yellow-white or greenish-yellow hues. These flowers may not be as showy as those of other plants, but they have their own charm. The blooms are surrounded by colorful bracts, which are modified leaves that often have a variegated pattern of white, green, and sometimes pink. Together, the flowers and braces create an interesting and eye-catching display.
When and How to Water Your White Ghost Cactus
To keep your White Ghost cacti happy and healthy, it's best to water them sparingly. In between waterings, let the soil dry out completely. This means waiting until the soil is dry to the touch before giving it a good drink. The White Ghost Cactus should only be watered when the soil is completely dry, typically every 2–3 weeks in active growth, and once a month or less during dormancy.
In the spring and summer, during the growing season, Euphorbia lactea variegata needs watering once every 2-3 weeks. The soak-and-dry method is the best technique to develop this plant. However, it's important to adjust the watering frequency based on the environmental conditions and the moisture level of the soil. In hot and dry climates, you may need to water it more often, while in cooler and more humid conditions, less frequent watering may be required.
During the winter months, when the cactus is in its dormant period, you should reduce the watering to once a month. It's best to water sparingly, only when the soil is completely dry. This helps prevent the risk of overwatering and allows the cactus to rest during its dormant phase.
Light Requirements - Where to Place Your Euphorbia Lactea
When growing the White Ghost Cactus indoors, it thrives in bright, indirect light for at least 4-6 hours a day. Place this potted plant near a window that receives plenty of sunlight throughout the day. However, be cautious of placing it in direct sunlight, especially during the intense afternoon sun, as it can scorch the delicate succulent.
If you notice your white ghost succulent stretching or becoming pale, it may be an indication that it needs more light. In that case, you can consider supplementing its light with a grow light to ensure it gets the necessary brightness.
If you are growing the White Ghost plant outdoors, this Euphorbia lactea variegata needs full to partial sun, for at least 4-6 hours a day. Just make sure to acclimate your Euphorbia white ghost gradually to the outdoor conditions if it has been indoors for an extended period. Start by placing your Euphorbia ghost cacti in a partially shaded area and gradually expose it to more sunlight over a few weeks.
Optimal Soil & Fertilizer Needs
When it comes to the soil, the White Ghost plants need well-drained soil and should be fertilized once a year in spring. You can create a suitable soil mix by combining equal parts of succulent potting mix, perlite, and coarse sand. Planet Desert specializes in succulents and has specialized succulent potting soil that includes an organic substrate with mycorrhizae to help with the growth of a healthy root system to help your white ghost Euphorbia succulents thrive.
During the growing season, which is typically in spring, you can fertilize your ghost cactus once a year. Choose a balanced (5-10-5), water-soluble NPK fertilizer specifically formulated for succulents. Follow the instructions for dilution and apply the fertilizer to damp soil to avoid any potential root burn. During the dormant period in winter, it's best to avoid fertilizing altogether.
Hardiness Zone & More
If you're growing the White Ghost plant outdoors, it is typically suited for USDA zones 9 to 11.
These zones generally have milder climates with frost-free winters and warm summers.
If you live in a region with colder temperatures, it's best to keep the succulent indoors or provide protection during winter months to prevent any damage from freezing temperatures.
It's important to avoid excessive humidity, as it can increase the risk of fungal diseases. Aim for a moderate humidity level, around 40% to 60%, to create a comfortable environment for your ghost cacti.
How to Grow Best Indoors the White Ghost Cactus
If you are growing your white ghost cactus indoors, it thrives in temperatures ranging from 60°F to 80°F. It's important to keep your Euphorbia lactea variegata away from drafts or sudden temperature fluctuations, as it prefers a stable and consistent climate. So, find a cozy spot in your home where the temperature remains within this range, and your white ghost will be happy.
Wildlife - Euphorbia lactea Attracts the Following Friendly Pollinators
The variegated Euphorbia lactea produces small, inconspicuous flowers that are primarily pollinated by bees, hummingbirds, and butterflies. These friendly pollinators are attracted to the nectar and pollen of the flowers, helping to ensure successful fertilization and seed production for this unique species.
Butterflies
Bees
Hummingbirds
Lady Bugs
Multi Pollinators
Other Birds
According to ASPCA, the variegated Euphorbia lactea is mildly toxic to humans and cats if ingested in large amounts. The milky sap of the plant can irritate the mouth and stomach and result in symptoms like diarrhea, vomiting, and lethargy.
Propagating White Ghost Cactus
To propagate the White Ghost Cactus, take healthy stem cuttings, let them callus for a few days, and plant them in a well-draining cactus mix. Place the pot in a warm, bright spot with indirect light and keep the soil lightly moist. Roots typically develop in a few weeks, especially when propagated in spring. You can also grow it from seeds, though this method takes longer and requires consistent moisture, warmth, and patience.
Key Takeaways
- The White Ghost Cactus is a rare and highly sought-after cultivar, prized for its striking white, silver, and pale green marbled stems that lack chlorophyll.
- This cactus-like euphorbia thrives in bright indirect light or filtered sun, making it an eye-catching choice for both indoor and outdoor displays.
