This monster's name appears to contradict its appearance, given that the roses which adorn this dragon's body are red rather than black. However, when one examines the name more closely, one notices that this monster's skin is actually black in color, and the name can be taken as a more literal description of this monster's nature.
To elaborate: Because the name says that this is a "Black Rose Dragon", it is assumed that it is a "dragon of black roses" and thus the name does not adequately describe the appearance. However, it actually means that this is a "Black Rose Dragon" – a black-colored variety of a species of dragon that adorns its body with roses – which is an accurate description of the monster.

This is one of four "Signer Dragons" that technically never got an upgrade throughout the Yu-Gi-Oh! 5D's series; the other three being "Ancient Fairy Dragon", "Black-Winged Dragon", and "Life Stream Dragon".
