Botanical classification: Heliopsis helianthoides var. scabra.

Variety denomination: ‘Summer Stripe’.


This application is co-pending with U.S. Plant Patent Applications filed for plants derived from the same crosses in the Inventor's breeding program that are entitled Heliopsis Plants Named ‘Summer Green’ (U.S. Plant patent application Ser. No. 13/065,162) and ‘Summer Pink’ (U. S. Plant patent application Ser. No. 13/065,161).


The present invention relates to a new and distinct cultivar of Heliopsis plant, botanically known as Heliopsis helianthoides var. scabra ‘Summer Stripe’ and will be referred to hereinafter by its cultivar name, ‘Summer Stripe’.

‘Summer Stripe’ was derived from a controlled breeding program conducted by the Inventor at his nursery in Schwamstedt, Germany. The breeding program focuses on obtaining new cultivars of Heliopsis with novel leaf and flower colors and superior garden performance. ‘Summer Stripe’ was selected in 2007 by the Inventor as a single unique plant derived in 2005 from the open-pollination between unnamed plants from his breeding program with the female parent identified with accession No. Clone ex H04011 and the male parent identified with accession No. Variegated seedling GU03.

Asexual reproduction of the new cultivar was first accomplished via stem cuttings in Schwarmstedt, Germany in 2008. The characteristics of this cultivar have been determined to be stable and are reproduced true to type in successive generations.


The following traits have been repeatedly observed and are determined to be the characteristics of the new cultivar of Heliopsis. These attributes in combination distinguish ‘Summer Stripe’ as unique from and all other varieties of Heliopsis known to the inventor.

    • 1. ‘Summer Stripe’ exhibits inflorescences with ray florets that are yellow in color with red cones.
    • 2. ‘Summer Stripe’ exhibits foliage that is variegated with blades that are pink, green and creamy white in color with dark green veins.
    • 3. ‘Summer Pink’ exhibits stems that are dark reddish in color.
    • 4. ‘Summer Pink’ blooms predictably as a one-year-old plant.

‘Summer Stripe’ can be compared to its parents. The female parent differs from ‘Summer Stripe’ in having purplish green foliage without variegation. The male parent differs from ‘Summer Stripe’ in lacking red stems. ‘Summer Stripe’ can also be compared to Heliopsis cultivar ‘Loraine Sunshine’ (U.S. Plant Pat. No. 10,690). ‘Loraine Sunshine’ differs from ‘Summer Stripe’ in having green stems, yellow inflorescences with a yellow cone, and lacking the ability to flower in the first year. ‘Summer Stripe’ can also be compared to cultivars from the same cross ‘Summer Pink’ and ‘Summer Green’. ‘Summer Pink’ differs in having inflorescences with ray florets that are yellow in color with an orange base. ‘Summer Green’ differs in having foliage that lacks any pink coloration.


The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Heliopsis. The photographs were taken of a one year-old plant as grown in a 3.5-liter container in a cold-story greenhouse in Lisse, the Netherlands.

The photograph in FIG. 1 provides a side view of a plant of ‘Summer Stripe’.

The photograph in FIG. 2 provides a close-up view of the leaves of ‘Summer Stripe’.

The photograph in FIG. 3 provides a close-up view of an inflorescence of ‘Summer Stripe’. The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description more accurately describe the colors of the new Heliopsis.


The following is a detailed description of the new cultivar collected on one year-old plants grown in 3.5 liter containers in cold-storey greenhouses in Lisse, The Netherlands in June with day temperatures ranging between 18° to 30° C. and night temperatures ranging between 8° and 18° C. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
