plant named ‘Sweet Summer Love’

Abstract

A new and distinct cultivar of Clematis plant named ‘Sweet Summer Love’ characterized by its upright and vining plant habit; relatively small leaves; freely flowering habit; long flowering period; and single fragrant flowers that are red purple and purple in color.

Description

Botanical designation: Clematis hybrida.

Cultivar denomination: ‘SWEET SUMMER LOVE’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Clematis plant, botanically known as Clematis hybrida and hereinafter referred to by the name ‘Sweet Summer Love’.

The new Clematis plant is a product of a planned breeding program conducted by the Inventor in Pruszków, Poland. The objective of the breeding program is to create new Clematis plants with fragrant purple-colored flowers.

The new Clematis plant originated from a cross-pollination conducted by the Inventor in July, 2003 in Pruszków, Poland of an unidentified selection of Clematis hybrida, not patented, as the female, or seed parent with an unidentified selection of Clematis hybrida, not patented, as the male, or pollen, parent. The new Clematis plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Pruszków, Poland.

Asexual reproduction of the new Clematis plant by cuttings in Pruszków, Poland since June, 2004 has shown that the unique features of this new Clematis plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Clematis have not been observed under all possible environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sweet Summer Love’. These characteristics in combination distinguish ‘Sweet Summer Love’ as a new and distinct Clematis plant:

• • 1. Upright and vining plant habit.
  • 2. Relatively small leaves.
  • 3. Freely flowering habit.
  • 4. Long flowering period.
  • 5. Single fragrant flowers that are red purple and purple in color.

Plants of the new Clematis differ primarily from plants of the parent selections in flower color.

Plants of the new Clematis can be compared to plants of the Clematis ‘Rubromarginata’, not patented. Plants of the new Clematis differ primarily from plants of ‘Rubromarginata’ in the following characteristics:

• • 1. Plants of the new Clematis are more compact than plants of ‘Rubromarginata’.
  • 2. Plants of the new Clematis flower for a longer period of time than plants of ‘Rubromarginata’.
  • 3. Plants of the new Clematis are more freely flowering than plants of ‘Rubromarginata’.
  • 4. Plants of the new Clematis and ‘Rubromarginata’ differ in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Clematis plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Clematis plant.

The photograph on the first sheet comprises a side perspective view of a typical flowering plant of ‘Sweet Summer Love’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Sweet Summer Love’.

DETAILED BOTANICAL DESCRIPTION
