Rosa cultivars come from various hybridization methods, they originate mainly from the species,
The rose has a vigorous and deep root, although in the plants originated from stakes this character is lost (small roots). Occasionally, they have a superficial rhizome. The stem is woody and may or may not end in a flower, they may be more or less erect, crawling or climbers and, generally, they have varied formations in their epidermis, such as stingers (the so-called "spines"). The branches are lignified, green, reddish or brown when young, changing to gray with aging. The leaves are composed, odd-shaped, petiolated, have sawn leaflets (like small teeth in the margin), smooth and, generally, each leaf contains five to seven leaflets and its brightness changes between varieties (bright, semi-glossy and matt).
