Description: The Unicorn Cactus, also known as Euphorbia lactea 'Cristata', is a striking succulent known for its fan-shaped, crested growth that resembles coral formations or the fantastical horn of a unicorn. This plant is often grafted onto a sturdy rootstock for support, creating a dramatic contrast between the thick, dark green base and the vibrant, often pink-tinged crests above. Despite its common name, the Unicorn Cactus is actually a Euphorbia species, not a true cactus. Its unique, almost otherworldly appearance makes it a favorite for collectors and those looking for a sculptural, show-stopping plant.
Care Instructions:
Light: The Unicorn Cactus thrives in bright, indirect light. It can tolerate some direct sunlight, but too much harsh light may cause sunburn on its delicate crests. Indoors, place it near a window with filtered light, or outdoors in a partially shaded spot.
Water: Allow the soil to dry out completely between waterings. Water deeply but infrequently, typically every 2-3 weeks during the growing season (spring and summer). Reduce watering in fall and winter when the plant enters dormancy. Be sure to avoid overwatering, as it can lead to root rot.
Humidity: The Unicorn Cactus does well in low to average humidity levels. It’s tolerant of dry air, making it well-suited for indoor environments.
Temperature: Euphorbia lactea 'Cristata' prefers warm temperatures and thrives in the range of 65°F to 80°F (18°C to 27°C). Protect it from cold drafts and temperatures below 50°F (10°C), as it is not frost-hardy.
Soil: Use a well-draining cactus or succulent soil mix to prevent water retention. Adding sand or perlite can improve drainage, keeping the roots dry and healthy.
Fertilizer: Feed the Unicorn Cactus with a diluted liquid fertilizer formulated for succulents or cacti once a month during the growing season. Avoid fertilizing in the winter when the plant’s growth slows down.
Pruning: Pruning is generally unnecessary for the Unicorn Cactus, but you can remove any damaged or unhealthy crests. Be cautious when handling, as Euphorbias produce a milky sap that can be irritating to the skin.
Styling Tips:
Sculptural Indoor Accent: With its coral-like, fan-shaped crests, the Unicorn Cactus makes a dramatic statement in any room. Place it in a simple, modern planter to highlight its unique form as a focal point in your home or office.
Desert-Themed Arrangements: Pair this plant with other succulents like Agave, Echeveria, or Aloe for a stunning desert-themed arrangement. Its striking form adds height and contrast to your succulent collection.

Container Garden: Place it on a sunny windowsill or patio in a container garden with other drought-tolerant plants. Its crested shape provides visual interest and texture to any outdoor space.
Minimalist Design: Display it on a shelf or a desk for a minimalist aesthetic. The plant’s sculptural silhouette can serve as an artistic centerpiece, bringing an organic, yet modern, element to your décor.
