According to the David Austin Site:

There is something a little special about white roses – they are all purity and light – and yet really good white roses are rare among English Roses and Hybrid Tea Roses alike. This is because white roses are very difficult to breed. ‘Claire Austin’ bears pleasingly cupped buds of a pale lemon shade which gradually open to form large, creamy white flowers of typical English Musk delicacy; their petals perfectly arranged in concentric circles, with a few more loosely arranged in the centre. They have a strong fragrance based on myrrh with dashes of meadowsweet, vanilla and heliotrope. Strong and particularly healthy. Undoubtedly one of our finest white roses to date
