Crassulaceae - Genus Aeonium - Aeonium urbicum


 
Aeonium urbicum (Chr.Smith ex Hornemann)Webb & Berth.

Nice unbranched, monocarpic shrub, 60 - 250cm high with a great terminal pyramid, up to 80cm long, of greenish-white flowers who are 9- to 10 parted. Leaves in broad, dense apical rosette, narrowly oblanceolate, glabrous, pale green to blue-glaucous, red-edged; margins ciliate.

Is endemic to Tenerife and his distribution reaches as from Anaga to Teno. We find this plant as follows : Puerto de la Cruz, La Orotava, Icod de los Vinos, Los Silos, El Palmar, Tegueste, Santiago del Teide, Masca and very frequent on walls and roofs in the La Laguna district. From sea-level up to 1850 meter.

Flowering period is from February  to September.

Hybridisation frequently with surrounding other Aeonium such as A. canariense, A. ciliatum, A. haworthii and A. holochrysum.

The unbranched form of A.ciliatum on the island of La Palma has often been mistaken as an Aeonium urbicum.

The A. urbicum var. meridionale with his white-pinkish flowers grows more in the south of the island.
