Origin of Name

Euphorbia lactea cv. 'White Ghost' is a cultivar name that vividly describes its unique appearance. The species name "lactea" is derived from the Latin word for "milky," referring to the white, latex sap that the plant produces when cut or damaged. The cultivar name 'White Ghost' alludes to the plant's striking white or pale green coloration, giving it a ghostly, ethereal look that distinguishes it from the standard green form of Euphorbia lactea.

Technical Description of Plant

Euphorbia lactea cv. 'White Ghost' is a striking succulent known for its sculptural, ridged, and branching form. Unlike typical green succulents, 'White Ghost' features a predominant white or very pale green coloration due to a lack of chlorophyll, which makes it highly prized for ornamental purposes. The plant forms a candelabra-like structure with branches that bear sharp, spine-like ridges along the edges. It can reach several feet in height when given the right conditions and time to grow. 'White Ghost' rarely blooms, especially in cultivation, with the main attraction being its vibrant, bone-white branches.

Origin of Plant

Euphorbia lactea is native to tropical regions of Asia, particularly India and Sri Lanka, where it grows in dry, forested areas. The 'White Ghost' cultivar is a result of selective breeding or a natural mutation and is primarily propagated for its striking appearance.

Conservation Status

As a cultivated variety, Euphorbia lactea cv. 'White Ghost' does not have a specific conservation status. The species Euphorbia lactea itself is not listed as endangered, but like all plants, sustainable cultivation practices are encouraged to ensure biodiversity and prevent overharvesting of wild populations.

Care Instructions

Euphorbia lactea cv. 'White Ghost' requires bright, indirect sunlight to maintain its pale coloration without risk of sunburn. It thrives in well-draining soil designed for cacti and succulents. Water sparingly, allowing the soil to dry out completely between waterings, and reduce watering in the winter months. As it lacks chlorophyll, 'White Ghost' may be grafted onto a green rootstock to ensure it receives the necessary nutrients for growth; care for both the graft and rootstock as needed. Protect from frost and extreme cold, as it is not cold-hardy. Handle with care, as the sap can be irritating to skin and eyes.
