My beloved planted some deep purple roses - I don't have the name
as of yet -
and after the second bloom the color is a lighter shade of purple.

I'm thinking that the PH of the soil, clay and planting soil mixed
might be
altering the color.

What does the knowledge base have on this ?

I'll pursue the name - there is a tag on the plant.

I know some plants move like litmus paper - pink acid and blue
base. I think
I have a rose working like that to a lesser amount.

I know that the last posting of this question was last month, but I
also am having the same problem with two of my rose bushes. One is
a
climbing rose called "Night Owl." It is a new bush, that we just
bought and planted about two months ago. The first time it bloomed,
it bloomed a very dark wine purple, which is the color that it is
suppose to be.....just beautiful. When the next set of blooms came
out, they were all a magenta color. Also at the same time, we
bought
and planted, a hybrid tea rose called "Black Bacarra." This rose,
as
the name suggests, is the deepest of purple, in which makes the rose
appear to be black in color. It now has bloomed twice, and both
times
the flowers have also been magenta in color. Other than what I
have
read about it possibly being the fact that the grafted part of the
rose died, which I know for a fact didn't happen in my case, is
there
any reason for this, as I would love the have the color be what it
is
suppose to be. Thanking you............L


Bloom color can vary due to cultural and weather factors. Your bushes
are too new for you to be overly concerned. I would be patient and see
how they do under different weather conditions.
