Hey David, I adore your St. Swithin!! I find the dark patch in the dorsal to be very attractive! When you look at St. Swithin, one of the most awarded hybrids ever, I am always looking for something new and exciting. Your baby has that.
It is just a little baby. Wait until it grows up and has a good deal of energy stored within, then it will really put out flowers.
Yours has above average color and for that reason it is a cool plant and to find that central patch of intense color only adds to its beauty in my eyes!
Very nice plant.
