Heliopsis plant named `Loraine Sunshine`

Abstract

A distinct cultivar of Heliopsis plant named `Loraine Sunshine,` characterized by its unique green and white variegated foliage; relatively compact growth habit; freely branching plant habit; large golden yellow daisy-type inflorescences that flower throughout the summer; numerous inflorescences per plant; and good container and garden performance.

Description

The present invention relates to a new and distinct cultivar of Heliopsis plant, botanically known as Heliopsis helianthoides scabra and referred to by the cultivar name `Loraine Sunshine`.

The new cultivar was selected in 1992 from seedling progeny from a cross of unidentified selections of Heliopsis helianthoides scabra in a cultivated outdoor area in Rhinelander, Wis.

Asexual reproduction of the new cultivar by terminal cuttings taken at Rhinelander, Wis., has shown that the unique features of this new Heliosis are stable and reproduced true to type in successive generations.

The following traits have been repeatedly observed and are determined to be the unique characteristics of `Loraine Sunshine`. These characteristics in combination distinguish `Loraine Sunshine` as a new and distinct cultivar:

1. Unique green and white variegated foliage.

2. Relatively compact growth habit.

3. Freely branching plant habit.

4. Large golden yellow daisy-type inflorescences that flower throughout the summer.

5. Numerous inflorescences per plant.

6. Good container and garden performance.

In contast to the new cultivar, plants of other known cultivars and selections of Heliopsis helianthoides scabra have solid green leaf color and are not compact.

The cultivar `Loraine Sunshine` has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new cultivar, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

The photograph on the first sheet comprises a top perspective view of a typical plant of the new Heliopsis.

The top photograph on the second sheet comprises a top perspective view of a typical plant of the new Heliosis in a garden setting.

The lower photograph on the second sheet comprises a close-up view of typical foliage and inflorescences of the new cultivar.

The floret and foliage colors in these photographs may vary from the actual floret and foliage colors due to light reflectance.
