Aeonium arboreum var. rubrolineatum (Svent.) H.Y.Liu
Aeonium arboreum var. rubrolineatum is a thick-stemmed, succulent plant with long leaves that darken in the sun, reaching an impressive up to 5 feet (1.5 m) tall. It can branch from the central stalk, but not so much as to become “shrubby”. The leaves are mostly green and lush during the winter months, then as the weather warms and they receive more light, they turn a yellow/brownish color with maroon stripes and markings on each leaf. Orange flowers form long clusters in the summer.
How to Grow and Care
Aeoniums do not like really hot or dry weather. They may go dormant in summer and do not require any water, except in very dry conditions. In extreme heat, their leaves will curl, to prevent excessive water loss. Growing them in moist shade will keep them growing, but their true growth season is winter to spring, when temperatures are cool (65–75˚F / 18–24˚C) and damp. In the winter, water whenever the soil has dried out. Test by poking your finger down into the soil an inch or two. Too much moisture or allowing them to sit in wet soil will cause root rot… – See more at: How to Grow and Care for Aeonium.
Propagate Aeoniums by stem cuttings, except for unbranched species which die after flowering and are propagated from seed. Take cuttings when the plant is actively growing, usually fall in USDA zones 9 through 11. Aeoniums go dormant in summer; cuttings taken while plants are dormant don’t root. Each leaf rosette dies after it blooms…. – See more at: How to Propagate Aeonium.
Cultural problems can cause massive damage to Black Rose plants, including leaf loss. Soggy soil and over-watering are perhaps the most common and serious cultural issues for Black Rose plants because too much water will drown the roots and may lead to root rot, particularly during cold weather… – See more at: Why Are Leaves Falling Off My Black Rose?
Native to La Gomera Island in the Canary Islands.
