All roses come down into one of three form classifications , being either bush , climbing or bush rosebush . However , more than two hundred of breeding and hybridizing have dish up to produce many thousands of rose species and cultivars , each with a singular mixture of characteristics .
Radial Symmetricallity
All roses have a flower head that is round in shape and is symmetric across its face and down its vertical axis of rotation . The flower emanates from a central ovary the sits at the center of the bloom under the petals and between the fleeceable down pointing sepals . The petals , no matter the number , distribute themselves equally around the central ovary , anthers and stamens .

Color
Roses come in a vast array of colors and in a expectant numeral of varying hues within the same color . The petals can be bi - people of colour or tri - color and bloom and appear in intimately every color save patrician and black . Some rise hybrid plants produce blooms with petals that are speckled , speckled or striped in pattern with contrast hues .
Scent
treasure for their rich , spicy - sweet scent , roses are often grown for their smell , but many varieties , peculiarly highly interbred advanced species , do not produce what we come to guess of as the traditional rose fragrance . Most mod rosiness have a scent , but not the same heady , deep aroma of old - fashioned garden roses such as tea and grandiflora . Roses with larger bloom of youth heads and dense , more velvety - textured petals are call back to produce more robust fragrance .
