Flowers and buds

Echeveria affinis usually reaches heights of up to 5 centimeters and only slowly forms shoots. The leaf rosettes are 6 to 8, sometimes up to 22 centimeters in diameter. The broad, lanceolate and short, pointed leaves are 3.4 to 7, sometimes up to 11 centimeters long and 1.1 to 2.4, sometimes up to 4 centimeters wide. They are green to almost black in color and have an almost flat surface.

The 20 to 30, sometimes up to 40 centimeter high inflorescence forms flattened cymes at the top . These have three to five spread branches with four to ten individual flowers each. The petals are up to 8 millimeters long, the sepals are pressed. The scarlet corolla is bluntly pentagonal, 10 millimeters long and about 8 millimeters in diameter at the throat.

The number of chromosomes is 2n = 60.
