description

Echeveria amoena grows branched and the shoots reach a length of 5 centimeters or more and a diameter of 3 to 5 millimeters. The leaf rosettes are 2.5 to 5.5 inches in diameter. The obovate-spatulate and thorn-pointed, glaucous- green leaves are 1 to 2 centimeters long and 0.7 to 1.5 centimeters wide. They are about 4 millimeters thick at the tip, which is often red.

The loosely cymös -rispige inflorescence forms winding and is about 10 to 20 centimeters long. The very small bracts are 4 to 10 millimeters, sometimes up to 20 millimeters long and fall off very easily. The slender flower stalk becomes 10 to 30 millimeters long. The slightly spread sepals are a maximum of 3 millimeters long. The cylindrical and salmon-orange corolla is 7 to 9 millimeters long and has a diameter of about 4 millimeters at the base.

The number of chromosomes is 2n = 66 or 132.
