Roses are aromatic, aesthetically pleasing perennials belonging to the Roseacea family and the Rosa genus.The perfect roses are those that have between 25 and 40 petals. These roses are considered to be ideally beautiful and the most aesthetically pleasing. Roses with a higher petal count often have trouble blooming consistently and struggle to take up enough water and nutrition to support the flower. Too many petals negatively affect the shape of the rose. These flowers often wilt faster or do not open all the way. The outer petals of the rose are typically the least aesthetically pleasing. Typically turning green or brown in color and often appearing wrinkled, these petals are known as guard petals. Guard petals protect the inner petals of the flower as they bloom, and also when they are cut and handled. .
