Discovering The Tree Aeonium
Aeonium arboreum, commonly known as the Tree Aeonium, is a striking succulent that captivates with its unique appearance and resilient nature. Belonging to the Crassulaceae family, this subtropical subshrub is native to the western Canary Islands, including Tenerife, La Palma, and Gran Canaria. Its distinctive rosettes of leaves and tall, conical inflorescences make it a favorite among succulent enthusiasts and gardeners worldwide.
Description and Features
In its natural habitat, Aeonium arboreum grows as a subshrub, reaching heights of up to 2 meters. The stems are upright or ascending, smooth, and can measure between 1 to 3 centimeters in diameter. At the end of these stems, you’ll find flattened rosettes of leaves, ranging from 10 to 25 centimeters in diameter. The leaves themselves are obovate to oblate lanceolate, pointed at the apex, and wedge-shaped at the base. They exhibit a glossy, often purple-colored surface and are adorned with curved eyelashes along the margins, adding to their visual appeal.
During the spring, Aeonium arboreum produces impressive inflorescences that are conical to ovate, with a length of 10 to 25 centimeters and a diameter of 10 to 15 centimeters. These inflorescences bear small, bright yellow flowers on fluffy stems, adding a cheerful splash of color to its surroundings.
Cultivation and Care
Aeonium arboreum thrives in sunny to slightly shaded locations and prefers well-draining, weathered volcanic soil. It is suited for cultivation in containers or in garden beds with good drainage. In temperate regions, it is often grown under glass to protect it from cold temperatures.
One of the popular cultivars of Aeonium arboreum is ‘Zwartkop’ (also known as ‘Schwartzkopf’), recognized for its striking dark purple foliage. Another variation, ‘variegatum’, features variegated leaves that add an extra layer of visual interest to gardens and landscapes.
Invasion Concerns
While cherished in its native habitat and cultivated environments, Aeonium arboreum has posed challenges as an invasive species in certain regions outside its natural range, such as southern Australia. Vigilance and responsible gardening practices are essential to prevent unintended spread.
Conclusion
Aeonium arboreum, with its bold structure and vibrant blooms, exemplifies the beauty and adaptability of succulents. Whether as a centerpiece in a garden or a potted marvel indoors, this species continues to enchant with its resilience and aesthetic charm. For those looking to add a touch of the Canary Islands’ allure to their surroundings, the Tree Aeonium stands ready to delight and thrive.
