USPP26422P2 - Agapanthus plant named ‘Blue Flare’ - Google Patents

Abstract

A new cultivar of Agapanthus named ‘Blue Flare’, characterized by its mid season blooming habit and re-blooms for up to 6 weeks, its blue self-cleaning flowers that are held primarily upright from pedicels (not drooping), and its medium tall plant height.

Description

Botanical classification: Agapanthus praecox.

Varietal denomination: ‘Blue Flare’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agapanthus praecox and will be referred to hereafter by its cultivar name, ‘Blue Flare’. ‘Blue Flare’ represents a new perennial herb grown for landscape use.

The new Agapanthus originated as the result of an on going breeding program in Cape Town, Republic of South Africa. The goal of the breeding program was to produce a cultivar of Agapanthus of medium size with a re-blooming habit.

‘Blue Flare’ originated as a seedling that arose from seed planted from open pollination of an unnamed plant of Agapanthus praecox from the Inventor's breeding program in 2002. The male parent is unknown. The new Agapanthus was selected as a single unique plant in December of 2004.

Asexual propagation of the new cultivar was first accomplished by in vitro propagation under the direction of the Inventor in December of 2005 in Cape Town, Republic of South Africa. Asexual propagation by division and tissue culture has determined that the characteristics of this cultivar are stable and are reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. The characteristics in combination distinguish ‘Blue Flare’ as a distinct cultivar of Agapanthus.

• • 1. ‘Blue Flare’ exhibits a mid season blooming habit and re-blooms for up to 6 weeks.
  • 2. ‘Blue Flare’ exhibits blue flowers that are held primarily upright from pedicels (not drooping.
  • 3. ‘Blue Flare’ exhibits flowers that are self-cleaning.
  • 4. ‘Blue Flare’ exhibits a medium-tall plant height.
    The female parent differs from ‘Blue Flare’ in having flowers that are drooping, not re-blooming and not self-cleaning. ‘Blue Flare’ can be compared to the cultivars ‘Peter Pan’ (not patented) and ‘Snowball’ (not patented). ‘Peter Pan’ is similar to ‘Blue Flare’ in being evergreen and in having blue flowers, but ‘Peter Pan’ differs from ‘Blue Flare’ in being shorter in plant height, in having flowers that are held more outward, and in lacking a re-blooming habit. ‘Snowball’ is similar to ‘Blue Flare’ in being evergreen, in having full flower heads and a re-blooming habit. ‘Snowball’ differs from ‘Blue Flare’ in having white flowers and a shorter plant height.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Agapanthus. The photographs were taken of a four year-old plant of ‘Blue Flare’ as field grown outdoors in Cape Town, Republic of South Africa.

The photograph in FIG. 1 provides a close-up view of an inflorescence of ‘Blue Flare’.

The photograph in FIG. 2 provides a close-up view of the flowers of ‘Blue Flare’.

The colors in the photographs are as close as possible with the photographic and printing technology utilized and color values cited in the detailed botanical description accurately describe the colors of the new Agapanthus.

DETAILED BOTANICAL DESCRIPTION
