Twinkle has a beautiful blue that will develop as the flower ages at the base of the flower. I was in a rush and took pictures too soon to show that feature and ? I took pictures in the shade. Not the best rule of thumb to display such a pretty flower.
You just have to imagine a beautiful blue rim at the base of the flower ?
Not so subtle partial view of the voluminous back garden .. blue is a stand out colour isn't it ?
