Description
Aeonium ‘Arboreum’, commonly known as the Tree Aeonium or Irish Rose, is a striking, evergreen succulent with large, glossy rosettes of dark green to purple-tinged leaves. Its rosettes are composed of numerous fleshy, spatula-shaped leaves that can develop deeper pigmentation in full sunlight. During late winter to early spring, this plant can produce bright, cone-shaped clusters of small, starry yellow flowers that rise above the foliage, adding a dramatic burst of color.
Growth Habit:
Aeonium ‘Arboreum’ is a branching succulent that can grow up to 3 feet tall and 2-3 feet wide, forming small, tree-like structures. Its stems are often woody and support clusters of rosettes at their tips. The plant has a natural tendency to spread and create a small thicket over time, making it a wonderful option for rock gardens or as a structural accent in larger succulent displays.
Watering Instructions:
This plant prefers a moderate watering schedule and should be watered only when the top 1-2 inches of soil are dry. During its active growing season in fall through spring, water every 1-2 weeks, depending on the climate. In the summer dormancy period, reduce watering significantly, only enough to keep the plant from drying out entirely. Avoid water sitting in the rosettes, as this can lead to rot.
Soil Needs:
Aeonium ‘Arboreum’ thrives in well-draining, sandy, or gritty soil. A high-quality succulent or cactus soil mix is ideal, or a blend of standard potting soil with sand and perlite can be used to ensure proper drainage. Good airflow and a pot with drainage holes are crucial for maintaining healthy roots.
Indoor or Outdoor Tips:
Indoor Care: Place in a location that receives bright, indirect light for at least 6 hours daily, such as near a south- or east-facing window. Rotate the plant periodically to promote even growth. Avoid high humidity areas, and ensure good air circulation around the plant.
Outdoor Care: Aeonium ‘Arboreum’ grows best in USDA hardiness zones 9-11 and enjoys mild temperatures between 65°F to 75°F. In regions with hot summers, provide partial shade during the peak afternoon hours to prevent sunburn. This plant does not tolerate frost well, so if temperatures drop below 32°F, it should be brought indoors or covered for protection.
