Origin of Name

Euphorbia Flanaganii Cristata 'Arm Crest' is a crested form of Euphorbia flanaganii. The species name honors the botanist J.D. Flanagan, who is noted for his work with Euphorbia species. The term 'Cristata' refers to the crested growth form, and 'Arm Crest' describes that the crest has originated from tissue of arms and not the stem.

Technical Description of Plant

Euphorbia Flanaganii Cristata 'Arm Crest' is known for its distinctive and ornamental crested form. Instead of the typical upright growth, this cultivar exhibits a horizontal, wavy, or fan-like cresting along the stem. The crested stems are green, often showing lighter green to yellow variegation, and they have a somewhat undulating appearance. This plant is also known as "Green Coral" due to its resemblance to underwater coral formations. The small leaves are ephemeral and grow along the ridges of the crest. While Euphorbia flanaganii typically produces small yellowish-green flowers, the 'Arm Crest' form is primarily grown for its unique foliage.

Origin of Plant

Euphorbia flanaganii is native to South Africa. The 'Arm Crest' variety, like other crested succulents, results from a rare mutation, and it has been selectively propagated for its distinctive growth pattern and ornamental appeal.

Conservation Status

As a cultivated variety, Euphorbia Flanaganii Cristata 'Arm Crest' does not have a specific conservation status. Cultivation of these unique forms in nurseries helps reduce the pressure on wild populations of Euphorbia species.

Care Instructions

Euphorbia Flanaganii Cristata 'Arm Crest' requires careful attention to maintain its ornamental appearance. It prefers bright, indirect light but should be protected from harsh direct sunlight, which can cause scorching. A well-draining cactus or succulent soil mix is essential. Water moderately during the growing season, allowing the soil to dry completely between waterings, and reduce watering in winter. This plant is not frost-tolerant and should be kept in a temperate environment. Handle with care, as the sap of Euphorbias can be irritating to skin and eyes.
