I know it does not look very rosy, but the buds have only just appeared. It has only just begun to realise that it is a rose, a climbing rose. In a couple of weeks, perhaps less, it will be a climbing rosy rose.
Something like this, although this was a few years ago.
When it really gets going we have roses everywhere outside.
And eventually the rosy petals fall, and the flower just leaves its seeds behind to remind it was there.
I planted the climbing rose 15 years ago and it still returns every year in its full glory.
