Helenium plant named `Coppelia`

Abstract

A new and distinct cultivar of Helenium plant named `Coppelia`, characterized by its single daisy-like coppery orange ray florets, with each floret being tipped orange yellow, and its flowering which commences late July and continues to early October. `Coppelia` forms compact groups of erect leafy stems which are ideal for use in borders.

Description

The present invention relates to a new and distinct cultivar of hardy perennial herbaceous plant of the genus Helenium, a member of the Compositae family, with the new cultivar being known by its cultivar name `Coppelia`.

This new cultivar of Helenium arose as a seedling form a breeding program carried out by the inventor Alan H. V. Bloom in Norfolk, England. The female parent was a presently unidentified cultivar of the species Helenium autumnale, and the male parent was a presently unidentified cultivar of the species Helenium bigelovi.

The original selection of the new cultivar was reproduced asexually by the inventor in Norfolk, England by vegetative propagation using basal cuttings. Each of the progeny of the first and second generations has been found to retain the characteristics of the original selection.

`Coppelia` has achieved the aim of being a quality flowering perennial with a shorter flowering height and flowers that do not reflex completely. The small, almost insignificant linear-lanceolate basal leaved clumps offer support to the erect leafy stems carrying the flowers. The classic single daisy-like flowers make an excellent display of coppery orange ray florets issuing from a central conical disc.

The new cultivar blooms from late July to early October in Norfolk, England. The flowers resemble those of typical H. autumnale cultivars in habit but not in color. `Coppelia` also has a resemblance to Helenium `Bruno` (unpatented) and Helenium `Butterpat` (unpatented) both in habit and in flower shape.

The plant thrives best in full sun and well drained soil.

The accompanying photographic drawings show typical flower and foliage characteristics of `Coppelia`, with colors being as true as possible with illustrations of this type. In this regard, the illustration may not depict the color designations and descriptions as they accurately appear in the botanical description.
