Dudleya abramsii subsp. calcicola
Limestone dudleya, Limestone Dudleya
Family: Crassulaceae · Type: perennial · Native
Conservation status: CNPS 4.3
Limestone dudleya is a rare (CNPS 4.3) California native perennial found in southern Sierra Nevada Mountains on open, rocky granite or limestone outcrops at elevations of 500 to 2,600 meters. Flowering from May to July, this succulent produces yellow flowers with darker yellow keels, sometimes tinged with red, in delicate inflorescences. Growing in compact rosettes 1 to 9 centimeters wide with short stems 0.3 to 2 centimeters across, it forms dense clusters on rocky terrain. Its fleshy leaves are lance-oblong to lanceolate, 1 to 6 centimeters long and 2 to 9 millimeters wide, with acute to slightly pointed tips that help it survive in harsh, exposed environments. The flower petals are 9 to 15 millimeters long, fused at the base and narrowly acute, reflecting the plant's adaptation to rocky, limestone habitats.
