ROSA, Rosaceae. Rose. The species or “wild” roses provide 
many showy spring-flowering shrubs, including climbers and 
trailers. The fruits or “hips” of many are large, abundant, and 
brightly colored; in some species they persist through the en¬ 
tire winter. These fruits are rich in vitamin C and some kinds 
are used for making preserves. The spines and prickles also 
vary greatly in size, color, and density, and in a few instances, in 
themselves, make the plant attractive [2J, 8C, nursery].
