Echeveria glauca

Familia: Crassulaceae (Crasuláceas)
planta suculenta de tipo herbáceo o sufruticoso, con hojas carnosas, redondeadas y dispuestas en roseta, en la que de modo lateral se inserta el tallo floral; flores provistas de cinco pétalos carenados, reunidas en inflorescencias ramificadas, muy pocas veces sencillas.
Las rosetas echan a menudo flores de color rojo, con el extremo libre e interior amarillo.
Están situadas sobre racimos de 10-25 cm de largo e inclinados hacia un lado.
Longevidad: de 3 a 7 años.

This is a beautiful low-growing large rosette-forming specimen with pale blue green leaves. Looks a lot like a lotus bowl when viewed from above. In late spring and early summer it produces stems of ovoid red flowers yellow inside.
H 20cm.
Echeveria is a large genus of succulents in the Crassulaceae family. They are native from Mexico to northwestern South America. The genus Echeveria is named after the 18th century Spanich botanist Atanasio Echeverria Codoy. Several of these species are outstanding garden plants. A large number offsets heavily and are given the common name of 'Hen and Chicks'.
Most species grow in the shade and can take some frost. Hybrids tend to be less accomodating about their growing conditions. All the species are drought resistant, but they grow better with regular deep watering and fertilizing.
They can be propagated with offsets, leaf cuttings, and if they are not hybrids, by seeds. Offsets is the easier way.
Most species lose their lower leaves in winter. Depending on your level of humidity, these leaves are fertile ground for fungus that can then attack the plant. It is better to remove them regularly. Another consequence is that after a couple of years the plants look untidy. It is better then to re-root the main rosette(s) and keep the rest of the plant for propagation.

Les rosettes de Echeveria Glauca sont spectaculaires... De 10 à 40 cm de diamètre, elles sont accolées les unes aux autres et s'étalent allègrement. La floraison est, elle aussi, très surprenante : petites clochettes bariolées jaune, rose, vert au bout de longues tiges qui partent du coeur de la plante. Comme beaucoup de plantes grasses, elle aime la chaleur et le plein soleil.
