CLEMATIS 'Allanah'

Gerald L. Klingaman

Family

Ranunculaceae

Botanical Name

CLEMATIS 'Allanah'

Plant Common Name

Allanah Clematis, Clematis, Late Large-flowered Clematis

General Description

The large, vibrant, velvety wine-red flowers of ‘Allanah’ bloom in late spring and early summer. Each of its broad petals taper at the base giving the blooms a distinctive appearance. It is a vigorous grower with a somewhat compact habit at maturity.

This hybrid clematis is a hardy deciduous woody vine that climbs by twining stems. The vines are lined with green compound leaves that appear in spring. The large wine-red flowers appear from spring to summer and are followed by fluffy clusters of silvery seeds.

Clematis prefers a position with at least five to six hours of sun per day and fertile, well-drained soil. They grow and flower best if their roots remain cool under a vegetative layer or thick mulch. The pretty ‘Allanah’ looks best trained along a wall, trellis, or arbor.
