The flowers are 10cm to 15cm across and the tepals have a lighter central bar and a tuft of creamy-yellow stamens. 'Blue Angel' is also known as 'Blekitny Aniol'.  The blooms open from slender buds and are delicately ruffled on the edges adding an elegance and grace to the display.

This large-flowered Clematis is an excellent choice for trellises and can be trained to climb a wall, fence or arbor. 'Blue Angel' has also been awarded the prestigious Royal Horticultural Society Award of Garden Merit for its outstanding features.
