Noteworthy Characteristics
Patrinia gibbosa is a compact, clump-forming plant which typically grows in a mound to 12-18" tall (infrequently to 2'). Tiny yellow flowers (to 3/16" across) appear in loose clusters (cymes to 4" across) above the foliage in summer. Coarsely-toothed, pinnately-cut, broad-ovate, blistered leaves (to 6" long).
Genus name honors Eugene L. M. Patrin (1724-1815), French mineralogist who travelled from 1780 to 1787 in Siberia and elsewhere in Asia and collected plants as well as minerals.
Specific epithet means swollen on one side.
