Flowers hermaphrodite, single, flat or flattish, upward- or outward-facing and also nodding or drooping, borne singly; pedicels light purplish red with white indumentum.

The cultivar produces many flowers with 5 sepals (there have been no flowers with 8 sepals yet); inside of sepals stone reddish purple with a dark red bar (approximately 59A); outside of sepals moderate purplish pink, central bar purplish red with dark purplish red ribs, with white indumentum.

Leaves divided with 3-5 leaflets, green maturing to mid-green, with white indumentum.

Named for the Registrant's granddaughter. The cultivar was from the same batch of seeds that produced Clematis 'Anne Mae'. Although similar in colour, the sepals of 'Kristen Helena' do not twist (they stay 'flat') and the plant produces a good number of flowers with 5, sometimes 7 sepals.
