I have heard complaints that all OGRs are pink and they all look alike. It is true that pink, like in Modern roses such as hybrid teas and miniatures, is a very common color, but not all roses are pink. There are several OGRs that are different, unusual, and some that one might consider bizarre. The rose also has no sex organs, so it can not be used in breeding programs. Love it or hate it, this rose is very popular for landscaping and a great filler material for rose arrangements.
Stripes are very popular.
There are OGRs whose blooms change color as they age. This trait comes from the China roses. Most of these blooms start off as yellow or light pink blooms, then turn to red or crimson before the petals fall. It's amazing to see different colored blooms on the same plant. There are also multiple colors in OGRs.
