First, let me introduce myself to the list since this is my first post here 
(I think).  We have a small city garden with minimal prime areas for roses, 
so we are very selective in what we grow.

Second, most roses today ARE clones (in the strict sense).  Certainly, all 
the modern NAMED VARIETIES are clones.  Whether they are produced from 
cuttings or budding, they are the genetic equivalents of each other.

There are a couple of very minor exceptions:  (1) Rarely, a variety will 
MUTATE (rose growers call this a "sport") and produce a different variety.  
(2) very, very old varieties which have been cloned for many generations can 
show a "genetic drift" and actually produce slightly different strains of 
the same variety.  I know this has happened with some ancient cultivated 
plants like figs and grapes.  I don't know if our rose varieties have been 
around long enough for that.

And, of course, there are those roses called wild roses or species roses  
(and their varieties) which grow from seeds and are not clones.

BTW, can we use HTML in this list or do we have to use just text? I know 
images are forbidden, but what about tags?
