First flowers

Hi,
    My second n. romieuxii from seed sown 3 years ago.  The first flower to bloom a few weeks ago was white, this one is more what I expected; a pale yellow.  It’s been wet here ( N Ireland) and there has been flooding in county Fermanagh.  Not on the same scale as in the Lake District in England.  Some farmland under water and roads closed.  I live near the sea at the top (North) and my soil is very sandy and free draining.  This weekend I hope to lift my dahlia tubers.  So far we havn’t had a frost to blacken the foliage.
    Photo attached shows the romieuxii flower.  It is wet as it was under one of the many drips in my greenhouse during the recent almost continuous rain.
                                                  Regards
