Aeonium arboreum ‘Zwartkopf’ is a striking succulent with clumps up to 3 feet (90 cm) tall gray-brown stems that often branch near their base. The long, bare stems hold large terminal rosettes (up to 8 inches/20 cm in diameter) of very dark purple, almost black leaves. Large conical clusters of bright yellow star-shaped blooms.
USDA hardiness zone 9b to 11b: from 25 °F (−3.9 °C) to 50 °F (+10 °C).
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?
