The Euphorbia flanaganii Monstrose Cristata 'Caudex Cristation' is a unique and rare succulent that stands out due to its intricate crested form. This mutation of the more common Euphorbia  flanaganii showcases a highly textured and undulating crest growing atop a thickened caudex (the swollen stem base). It is prized by collectors for its alien-like and sculptural appearance, making it a centerpiece in any succulent collection. 

It is also known as “Crested Medusa’s Head” or “Crested Euphorbia flanaganii,” due to its contorted, coral-like structure. The term “Cristata” in its name highlights the fan-like crests, which are formed due to genetic mutations that cause abnormal growth. 

This Euphorbia flanaganii variety is distinguished by its crested radial growth.

The plant in the image reveals densely packed, intricate ridges of green stems forming a coral-like structure, radiating from a broad caudex base. The combination of spiny ridges and undulating patterns makes it visually fascinating.

The texture of the caudex shows the characteristic geometric pattern common in crested succulents, adding to its sculptural appeal.

The color of the stems is vibrant green, contrasting beautifully with the rocky substrate, which emphasizes its unique form.

It can grow up to 6-12 inches in height, with a spread that can extend similarly in width due to the crest’s growth. The caudex remains compact, but the crests may spread outward, forming a fan-like structure. The plant in the image shows a well-formed crest that expands outward horizontally more than vertically, which is common in monstrose forms. 

The Monstrose Cristata has a radial pattern resembling a Medusa's head, while the Euphorbia  flanaganii  cristata Green Coral variety features a fan-shaped, crested growth with convoluted ridges resembling waves or crests. 

The flowers of Euphorbia flanaganii Cristata are quite small and not very showy. They typically appear as small yellow or greenish cyathia, the characteristic floral structure of the Euphorbia genus. These flowers emerge from the ridges of the crest, adding a delicate contrast to the otherwise rigid appearance of the plant. While not significant in terms of appearance, they are a sign of the plant's health and maturity. Though the flowers are small, they may attract small pollinators such as insects.  

When it comes to care, this plant thrives in bright, indirect light or full sun. Indoors, it should be placed near a sunny window, while outdoors, it can handle full sun as long as it’s not scorching hot. In very intense light, the crest may take on more vibrant tones. Well-drained soil is essential for this plant, as it is susceptible to root rot if kept in overly moist conditions. 

The Euphorbia flanaganii Cristata is drought-tolerant and should be watered sparingly. Allow the soil to dry out completely between waterings, especially in winter when the plant’s growth slows.  

The ideal indoor temperature for your crested Euphorbia is between 60-85°F. This plant can be grown outdoors in USDA zones 9-11. In colder areas, it must be brought indoors or grown in containers that can be moved as temperatures drop. Fertilize sparingly with a balanced, diluted succulent NPK fertilizer during the growing season in the spring.
