You definately have a grafted plant. What you have to watch out for
is that the mother plant will take over, given the half of a chance.
Here's a link on the Rosa Europeana

From the looks of it, you have a mis-labelled rose. I say that
because wild roses tend to be red, and you say the main flowers are
yellow. Here's a video of how to remove sucker growth from roses,
which is what I think the red flowers are likely to be from:

I am pretty well a novice when it comes to roses, but I am keen on
becoming more expert in roses.
Back in March I bought a smallrose bush about 2 foot in height , at my
local flower stand, it is labelled a Rosa Europeana. It is growing
great and now taller than I am, it must be beginners luck that It seems
happy in the spot I planted it. What has become apparent though, is
that it has beautiful yellow roses blooming and now there are two dark
crimson red rose buds opening up. It is possible that the yellow roses
were grafted onto the 'mother' plant is it were?

Anyway, I think I got a good bargain for a fiver.
