Small Leaved Rose
Rosa minutifolia
  
About Small Leaved Rose (Rosa minutifolia) Nurseries Show All Photos Rosa minutifolia is a rare species known by the common names Baja rose and small-leafed rose. This is a very spiny, dense shrub native to the chaparral and maritime succulent scrub plant communities of Baja California and barely crossing the border into San Diego County where it's habitat has been almost completely destroyed. It is on CNPS list 2B.1 and is listed as Endangered by the state. It is being propagated at the San Diego Botanic Garden as a conservation measure, and 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. It is slow growing and individual plants remain fairly compact, unlike other wild roses. Though very drought tolerant, it accepts some summer water and will often bloom in response. It has a very long flowering season; with supplemental water it is essentially year round. It's a good choice for drought tolerant gardens especially in the southern coastal counties.
