Q. Is there a black rose named in honor of Justice Oliver Wendell Holmes? W. G.
A. This name has been given by Father Schoener, a Santa Barbara priest and rosiculturist, to the velvety black rose which he has grown.

This is the only other reference I can find for 'Souvenir de Catherine Breslau'. Sadly, there is no description.

Miracle Man of Roses

Close to the avenue of giant rose trees is an insignificant bush. It blooms irregularly, but when it does, the world sees a black rose. Only a tiny bit of dark red on the edge of some of the petals shows how it has been bred from crossing the very dark-red plants. Of the creation of this bud, Dr. Schoener says, "It is only logical to presume that if two very dark roses were crossed the next generation would contain a rose darker than either of the originals. Remember, that is only a theory. Science is not made of theories, but of facts. So I made my experiments, and eventually succeeded."
