Euphorbia canariensis is endemic to canary islands. It is the plant symbol of the island of Gran Canaria. Very picturesque plant with dark color skin and spines in pairs like cow horns.

Etymology

The genus name "Euphorbia" is derived from the name of Euphorbus, a Greek physician who is credited with the early medicinal use of the plant's latex. The species name "canariensis" indicates its geographical association with the Canary Islands, where this plant is predominantly found. The term "canariensis" literally translates to "from the Canary Islands," highlighting its native habitat.

Synonyms

Euphorbia canariensis has previously been referred to by several synonyms due to taxonomic revisions. Some common synonyms include "Euphorbia edulis" and "Euphorbia lasiocarpa." Such synonyms arise from historical nomenclature and classification changes, emphasizing the need for continuous study in botany.

Origin

Euphorbia canariensis is endemic to the Canary Islands, specifically thriving on the volcanic soils of islands like Tenerife and Gran Canaria. These islands provide a unique environment characterized by rocky terrain, dry climates, and significant sunshine, which this species has adapted to over time.

Description

Euphorbia canariensis is a stout, columnar succulent that can reach heights of 3 to 6 feet (0.9 to 1.8 meters). The plant features a thick, upright stem that is typically ribbed and may exhibit a grayish-green color. Its surface is adorned with small, spiny projections that serve both decorative and defensive purposes. In the spring, Euphorbia canariensis produces inflorescences of small, cup-shaped flowers, which are yellow-green in color and attract pollinators.

Conservation Status

Euphorbia canariensis is not currently classified as threatened or endangered. However, habitat loss due to urbanization and agricultural expansion poses potential risks to this species in its natural range. Conservation efforts are crucial to ensure sustainable practices in regions where it grows, preserving its natural habitat.

Care Instructions

Euphorbia canariensis is relatively easy to care for, making it a popular choice among succulent enthusiasts. Here are key care guidelines:

• Light: Prefers full sun to partial shade. Providing sufficient light is critical for healthy growth.
• Water: Allow the soil to dry out completely between waterings. Overwatering is a common issue and can lead to root rot.
• Soil: Use a well-draining cactus or succulent mix to ensure proper drainage and prevent excess moisture retention.
• Temperature: Thrives in warm conditions, with an ideal temperature range of 65°F to 85°F (18°C to 29°C). Protect from temperatures below 30°F (-1°C), as it is not frost-hardy.
• Humidity: Prefers low humidity levels, in line with its arid native habitat.
• Fertilization: During the growing season (spring and summer), use a diluted cactus fertilizer sparingly to encourage robust growth.
