''Dudleya abramsii'' is a succulent plant known by the common name Abrams' liveforever. It is native to California and northern Baja California, where it grows in rocky areas in a number of habitat types. It is a fleshy perennial forming a small basal cluster of leaves around a central caudex. The thick, waxy leaves are triangular to oblong and usually pointed, reaching up to 11 centimeters in length, but often remaining much smaller. The entire rosette is generally only a few centimeters wide. The inflorescence is a mostly erect, branching stem lined with pointed bracts and bearing up to 15 flowers. The flower has five small, thick sepals at the base of five pale yellow petals each about a centimeter long. There are several subspecies: *''D. a.'' ssp.
