A rose is a flower in the Rosaceae family. Although there are hundreds
of species of wild roses, these flowers have also been classified within
three main groups. There are Wild Roses, Old Garden Roses, and Modern
Garden Roses.
Wild Roses appear much different than what you may have seen in the
near by florist or garden. This mostly deciduous inhabiting species
has four to five petals and varies in colors; however, they are mostly
pink or white.
Old Garden roses have significant historical background amongst origin,
nomenclature, and cultivation. They differ vastly from each other in
regards to how many petals they have, whether they are shrubs or climbers,
and how often they bloom.
Modern Garden Roses can sometimes be confused with old garden roses
because the parent roses may be from that category. However, this group
can be characterized by flower formation and growth. This type of flower
is what you would normally see in a florist and is most likely the white
rose sample used above.
(On a side note, the color white for roses symbolizes innocence and
purity!)
