Convolvulus plant named ‘Sumcov 01’

Abstract

A new and distinct cultivar of Convolvulus plant named ‘Sumcov 01’, characterized by its trailing plant habit; freely flowering habit; vigorous plant growth habit; and single white-colored flowers.

Description

Botanical classification/cultivar designation: Convolvulus sabatius cultivar Sumcov 01.

BACKGROUND OF THE INVENTION

The present Invention relates to a new and distinct cultivar of Convolvulus plant, botanically known as Convolvulus sabatius, and hereinafter referred to by the name ‘Sumcov 01’.

The new Convolvulus is a product of a planned breeding program conducted by the Inventor in Lüdinghausen, Germany. The new Convolvulus originated from a cross-pollination made by the Inventor of two unnamed selections of Convolvulus sabatius, not patented. The new Convolvulus was selected by the Inventor in 2002 in a controlled environment in Lüdinghausen, Germany.

Asexual reproduction of the new cultivar by terminal cuttings in Lüdinghausen, Germany since 2002, has shown that the unique features of this new Convolvulus are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the cultivar Sumcov 01 have not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment 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 ‘Sumcov 01’. These characteristics in combination distinguish ‘Sumcov 01’ as a new and distinct Convolvulus cultivar:

• • 1. Outwardly spreading and trailing plant habit.
  • 2. Freely flowering habit.
  • 3. Vigorous plant growth habit.
  • 4. Single white-colored flowers.

Plants of the new Convolvulus are more outwardly spreading and differ in flower color when compared to plants of the parent selections.

Plants of the cultivar Sumcov 01 can be compared to plants of the Convolvulus cultivar Compact, not patented. However, in side-by-side comparisons conducted in Lüdinghausen, Germany, plants of the new Convolvulus and the cultivar Compact differed in the following characteristics:

• • 1. Plants of the new Convolvulus were more outwardly spreading than plants of the cultivar Compact.
  • 2. Plants of the new Convolvulus were more freely flowering than plants of the cultivar Compact.
  • 3. Plants of the new Convolvulus had larger flowers than plants of the cultivar Compact.
  • 4. Flowers of the new Convolvulus and the cultivar Compact differed in flower coloration as plants of the cultivar Compact had violet-colored flowers.

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. Colors in the photographs may differ slightly from the color values cited in the following detailed botanical description which accurately describe the colors of the new Convolvulus.

The photograph on the first sheet comprises a side perspective view of a typical plant of ‘Sumcov 01’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flower and leaves of ‘Sumcov 01’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
