Rosa minutifolia is a species of rose known by the common names Baja rose and small-leafed rose. This is a very spiny, dense shrub native to the chaparral plant community of Baja California and San Diego County, California. It is grown elsewhere as an ornamental. The branches of the shrub are gray to red-tinted and covered in long and short spines. The shiny toothed leaves are composed of small leaflets only about half a centimeter wide. The blooms are generally bright pink with many yellow-anthered stamens and masses of prickles on the undersides.
