Verbascum plant named ‘Flower of Scotland’

Abstract

A new and distinct cultivar of Verbascum plant named ‘Flower of Scotland’, characterized by its compact and upright plant habit; medium green-colored foliage; unique greyed purple to greyed red-colored flowers; and good garden performance.

Description

Botanical designation: Verbascum hybrida.

Cultivar denomination: ‘Flower of Scotland’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Verbascum, botanically known as Verbascum hybrida and hereinafter referred to by the name ‘Flower of Scotland’.

The new Verbascum is a naturally-occurring whole plant mutation of an unnamed selection of Verbascum hybrida, not patented.

The new Verbascum was discovered by the Inventor in a controlled environment in Gretna Green, Scotland in 1999.

Asexual reproduction of the new Verbascum by tissue culture in a controlled environment in Dievers, The Netherlands since 2002, has shown that the unique features of this new Verbascum are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar Flower of Scotland has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices 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 ‘Flower of Scotland’. These characteristics in combination distinguish ‘Flower of Scotland’ as a new and distinct cultivar of Verbascum:

• • 1. Compact and upright plant habit.
  • 2. Medium green-colored foliage.
  • 3. Unique greyed purple to greyed red-colored flowers.
  • 4. Good garden performance.

Plants of the new Verbascum differ from plants of the parent selection in the following characteristics:

• • 1. Plants of the new Verbascum are more compact than plants of the parent selection.
  • 2. Plants of the new Verbascum and the parent selection differ in plant growth habit.
  • 3. Plants of the new Verbascum and the parent selection differ in flower color.

Plants of the new Verbascum can be compared to plants of the cultivar Buttercup, disclosed in U.S. Plant Pat. No. 14,793. Plants of the new Verbascum and the cultivar Buttercup differ in the following characteristics:

• • 1. Plants of the new Verbascum are more compact than plants of the cultivar Buttercup.
  • 2. Plants of the new Verbascum and the cultivar Buttercup differ in plant growth habit.
  • 3. Plants of the new Verbascum and the cultivar Buttercup differ in flower color.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Verbascum, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Verbascum. The photograph comprises a side perspective view of a typical flowering plant of ‘Flower of Scotland’ grown in an outdoor nursery.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photograph and following observations, measurements and values describe plants grown in Hiliegom, The Netherlands, under commercial practice during the summer in an outdoor nursery with day temperatures ranging from 14° C. to 33° C. and night temperatures ranging from 7° C. to 18° C. Plants had been growing for about two years when the photograph and description were taken. 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.
