Habitat:

A. Arboreum is a plant native to Canary Islands. The cultivar “Emerald Ice” was created by Altman Plants.

Description:

A. “Emerald Ice” is a slow growing succulent which can grow up to 30 cm in height. The plant forms a rosette of bright green leaves with the edge cream colored. Fleshy leaves are arranged in a geometric and concentric pattern, very fascinating. Due to the shape and color of the leaves that resemble the gem, the plant takes the name of “Emerald”, and for the white margin the name of “Ice”. The plant does not develop a stem like the others species of this genus, but the formation of the rosette is common with the other species. The older leaves at the base of the rosette tend to turn pink.

Cultivation:

The Aeonium Arboreum is a slow growing plant very easy to cultivate. The perfect soil is a well-drained soil that let the water to drain away and avoid root rot. For this succulent the best sun-exposure is direct sunlight, so you can place it outdoors. The minimum temperatures that the plant can withstand are 7 ° C, below this temperature it begins to suffer and going down further it no longer survives. For the watering you can water regularly in the growing season but check that the soil is completely dry before watering again. Repotting is not required, because the roots of the plant do not spread too much and the growth of the stem is poor.

Propagation:

Because Emerald Ice is a particular cultivar, in order not to lose the characteristics of the plant, propagation can only be done by cutting. By cutting you can use the offsets that grow at the base of the plant. Cut the offset as close as possible to the base of the stem and then let it dry; after a few days the cut surface will dry and a callus will form, then place the cutting in a mixture of sand, soil and pumice.

Curiosity:

The plants of the genus Aeonium are very efficient in the depuration of the environment and very robust. For these characteristics they are, among the plants, studied by NASA for future use inside the spacecraft. Its name derives from the greek word aionios, which means eternal, immortal, a name that has earned both for its strength and for its affinity with the Sempervivum genus. In fact the Aeonium are plants extremely robust even for the standard of the great family of succulents; they can tolerate long periods of drought, as well as short periods of intense cold.
