Aeonium arboreum var. rubrolineatum (Svent.) H.Y.Liu
Aeonium arboreum subsp. rubrolineatum, Aeonium rubrolineatum
Aeonium arboreum var. rubrolineatum is a succulent shrub with lance-shaped leaves crowded in rosettes at the end of the quite thick branches. It grows up to 5 feet (1.5 m), branching from the central stalk. Leaves are mostly green during the winter, and then as the weather warms and they receive more light, they turn brownish-yellow with maroon stripes and markings. When the plant goes dormant in summer, the rosettes are very small, and the branches are often almost leafless.
The flowers are star-shaped, pale yellow, commonly striped with reddish, and appear in attractive semi-globose to ovoid, up to 6 inches (15 cm) long clusters in summer.
Aeonium arboreum var. rubrolineatum is native Canary Islands (La Gomera). It occurs in a small area in the central and western part of the island, growing on rocky slopes in forest clearings and forest edges at elevations between 2,620 and 3,940 feet (800 to 1,200 m).
USDA hardiness zones 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
How to Grow and Care
Tree Aeonium grows best in full sun during the cooler months and in coastal areas. When grown inland or during the summer, provide this succulent with afternoon or partial shade. Avoid placing Tree Aeoniums in sites with western sun exposures.
Though Tree Aeoniums tolerate various soil types, as long as they're well-drained, it prefers light, porous soil. Therefore, you may want to amend your planting site with sand and limestone chips. For container gardening, plant Tree Aeonium in a moderately moist medium with excellent drainage.
This drought-tolerant plant hates water around its roots, so avoid excessive watering. In the wild, these succulents go dormant in summer, so water sparingly during the hotter months, allowing plants to dry out between waterings. In the winter, reduce watering to once per month.
