The flowers have six to eight broad, overlapping tepals which taper along slightly wavy margins to pointed tips. The newly opened blooms can have a soft pinkish bar that quickly fades away as the flowers open. The stamens have white filaments and pale yellow anthers. H.F. Young is a spectacular sight in late spring and early summer.

Pruning will help keep your clematis vines healthy.  Pruning the dense tangle of stems opens the remaining shoots to air and light which encourages healthy growth and reduces the incidence of rot and disease.

Group 2 Clematis bloom in late spring on last years growth and again in summer on the new growth.  This group require a little more care when pruning as if you cut back too heavily after the first flush you will reduce the number of flowers on show in summer.

Prune back lightly to a set of strong buds in winter and remove any dead stems and trim to tidy the plant. After the first flush of flowers in spring, remove the spent flowers to encourage new growth and a stronger second flush in summer. Feed with a good quality liquid fertiliser after pruning to encourage growth.
