Vegetative characteristics
Sempervivum pisidicum grows as a rosette plant with a diameter of 2 to 9 centimeters and forms runners 2 to 5 centimeters in length. The oblong spatulate, short tapering leaves are light green and have a purple tip. The leaf blade is 30 to 50 millimeters (rarely up to 85 millimeters) long and 10 to 18 millimeters wide.
Generative characteristics
The flowering shoot reaches a length of 12 to 45 centimeters. It has elongated, lanceolate, long, pointed leaves that are shorter than those of the leaf rosette . The inflorescence consists of long branched cymes with up to 15 flowers. The 13 to 15-fold flowers are on thick, 3 to 15 millimeter long flower stalks and have a diameter of 1.8 to 2.2 centimeters. Their triangular, tapering, green, 4 to 5 millimeter long petals are fused together over a length of up to 1.5 millimeters. The linear-lanceolate, keeled sepals have a length of 8 to 10 millimeters and are 2 to 2.5 millimeters wide. They are purple on the inside and green on the outside. The triangular to awl stamens are dark purple, the bald anthers are yellow. The bald stylus is about 2 millimeters long. The small nectar flakes are semicircular.
