Aeonium arboreum ‘Zwartkop’ aka Black rose

The flowers are actually leaves, in older plants they can be as large as 8″ across. The true flowers are a bright yellow, and look like small daisies. I’ll post photos once it blooms. These just arrived this week.

The plant grows long stems with sparse clumps of rosettes. It looks like a small tree when fully grown (~3′)

I’m hoping to grow it in pots outside. It’s rated for zones 9-11 so it’s probably best grown as a house plant.

Grow it in full sun, well drained soil, same as you would for any succulent. Water it more in the summer, less in the winter, giving it a thorough soaking and letting it go almost dry between waterings.

Propagation is by cuttings in early spring. The two plants in the photos are cuttings, I’ve potted them up in wet soil, I’ll let the soil get drier and give them more light over the next few weeks.

The earliest mention of this plant I could find was late 1980s where it is mentioned as a houseplant or plant for warm, dry landscapes.

It’s in the same plant family as jade, Crassulaceae. It’s native to the Canary Islands where it prefers to grow on hillsides.
