CROSS REFERENCE TO RELATED APPLICATIONS

This application is related to a European plant breeders' rights application, Application No. 2023/0971 filed on May 4, 2023, under 35 U.S.C. 119(f), the entire contents of which is incorporated by reference herein. The information for the plant breeders' rights application was received directly from the Inventors. This application is also co-pending with U.S. Plant Patent Applications filed for plants derived from the same breeding program that are entitled Agapanthus Plant Named ‘DWAgHyb01’ (U.S. Plant patent application Ser. No. 18/112,983) and Agapanthus Plant Named ‘DWAgHyb02’ (U.S. Plant patent application Ser. No. 18/112,907).

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agapanthus of hybrid origin and will be referred to hereafter by its cultivar name, ‘DWAgHyb05’. ‘DWAgHyb05’ represents a new perennial grown for landscape and container use.

The new cultivar was derived from a controlled breeding program by the Inventors in Hartbeespoort, North West Province, South Africa. The goal of the breeding program was to develop a new cultivar of Agapanthus that re-blooms, has bi-color flowers, has a compact to medium-sized plant habit, and has resistant to rot caused by Erwinia sp. The Inventors made a cross in October of 2015 between unnamed and unpatented proprietary plants of Agapanthus from the Inventors' breeding program as both the female and male parents. The Inventors selected ‘DWAgHyb05’ in October of 2017 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished by division by one of the Inventors in Hartbeespoort, North West Province, South Africa in October of 2017. Asexual propagation by division and tissue culture utilizing meristematic tissue has determined that the characteristics of the new 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 ‘DWAgHyb05’ as a distinct cultivar of Agapanthus.

• • 1. ‘DWAgHyb05’ exhibits good resistance to root rot and crown rot.
  • 2. ‘DWAgHyb05’ exhibits bi-color flowers (white and purple).
  • 3. ‘DWAgHyb05’ exhibits a long flowering period with a re-blooming habit.
  • 4. ‘DWAgHyb05’ exhibits a fast growth habit with blooms at a young age.
  • 5. ‘DWAgHyb05’ exhibits a compact plant habit and medium plant height.
  • 6. ‘DWAgHyb05’ exhibits a high flower count per umbel (dense).
  • 7. ‘DWAgHyb05’ exhibits numerous inflorescences.

The female parent of ‘DWAgHyb05’ differs from ‘DWAgHyb05’ in having an inferior reblooming habit. The male parent of ‘DWAgHyb05’ differs from ‘DWAgHyb05’ in having flowers with the bi-color less prominent and paler in color. ‘DWAgHyb05’ can be most closely compared to the Agapanthus cultivars ‘WP001’ (U.S. Plant Pat. No. 27,357), and ‘Ambic001’ (U.S. Plant Pat. No. 25,519), ‘DWAgHyb01’, and ‘DWAgHyb02’. ‘WP001’ is similar to ‘DWAgHyb05’ in being floriferous and re-blooming and having a compact plant habit but differs from ‘DWAgHyb05’ in having flowers that are all white in color. ‘Ambic001’ is similar to ‘DWAgHyb05’ in having bi-colored flowers. ‘Ambic001’ differs from ‘DWAgHyb05’ in having a slower growth habit, a slightly taller plant height and leaves that are more narrow in shape, and in lacking rebloom and an evergreen habit in warm climates. ‘DWAgHyb01’ and ‘DWAgHyb02’ are both similar to ‘DWAgHyb05’ in having medium plant heights, high flower counts per umbel, and good resistance to root and crown rot. ‘DWAgHyb01’ differs from ‘DWAgHyb05’ in having flowers that are blue in color. ‘DWAgHyb02’ differs from ‘DWAgHyb05’ in having flowers that are dark purple in color.
