The genus Echeveria is named after the 18th century Spanish botanist Atanasio Echeverria Codoy. Echeveria 'Ghost', a hybrid of unknown genetics, forms rosettes of fleshy glaucous white-blue leaves. Orange bell-shaped flowers on short raceme frequented by hummingbirds. Good for windowsill culture or dish gardens. In habitat, many Echeverias grow on rocky outcroppings at higher altitudes. In this habitat, the water drains quickly away from the roots of the plant, never allowing the plant to remain waterlogged. For this reason, it is essential in cultivation to use a very porous soil, which will allow quick drainage. Bright light is required to prevent "stretching" of Echeverias ("stretching" occurs when a moderately fast growing plant such as an Echeveria, is grown in dim light or over-fertilized, which causes overly lush growth that contributes to weak, pallid plants). Water thoroughly when soil is dry to the touch. Protect from frost.
