plant named ‘PMB011’

Abstract

A new and distinct cultivar of Agapanthus plant named ‘PMB011’, characterized by its compact and upright plant habit; vigorous growth habit; early flowering habit; numerous star-shaped flowers with violet blue and white-colored perianth segments arranged on upright and strong scapes; and ease of propagation.

Description

Botanical designation: Agapanthus orientalis.

Cultivar denomination: ‘PMB011’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Agapanthus plant, botanically known as Agapanthus orientalis and hereinafter referred to by the name ‘PMB011’.

The new Agapanthus plant is the product of a planned breeding program conducted by the Inventors in Pine Mountain, Queensland, Australia. The objective of the breeding program is to create new compact and vigorous Agapanthus plants with early flowering habit and attractive bi-colored flowers.

The new Agapanthus plant is the result of a cross-pollination made by the Inventors in 2009 of Agapanthus orientalis ‘Snowflake’, not patented, as the female, or seed, parent with a proprietary selection of Agapanthus orientalis known as code name PMB01, not patented, as the male, or pollen, parent. The new Agapanthus plant was discovered and selected by the Inventors as a single flowering plant from within the progeny of the stated cross-pollination in a controlled environment in Pine Mountain, Queensland, Australia during the spring of 2011.

Asexual reproduction of the new Agapanthus plant by divisions in a controlled environment in Pine Mountain, Queensland, Australia since the spring of 2011 has shown that the unique features of this new Agapanthus plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Agapanthus have not been observed under all possible combinations of 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 ‘PMB011’. These characteristics in combination distinguish ‘PMB011’ as a new and distinct Agapanthus plant:

• • 1. Compact and upright plant habit.
  • 2. Vigorous growth habit.
  • 3. Early flowering habit.
  • 4. Numerous star-shaped flowers with violet blue and white-colored perianth segments arranged on upright and strong scapes.
  • 5. Ease of propagation.

Plants of the new Agapanthus differ primarily from plants of the female parent, ‘Snowflake’, primarily in perianth segment color as plants of ‘Snowflake’ have white-colored perianth segments.

Plants of the new Agapanthus differ primarily from plants of the male parent selection primarily in perianth segment color as plants of the male parent selection have violet blue-colored perianth segments.

Plants of the new Agapanthus can be compared to plants of Agapanthus orientalis ‘PMN06’, disclosed in U.S. Plant patent application Ser. No. 11/903,036. In side-by-side comparisons conducted in Pine Mountain, Queensland, Australia, plants of the new Agapanthus and ‘PMN06’ differed in the following characteristics:

• • 1. Plants of the new Agapanthus were more compact than plants of ‘PMN06’.
  • 2. Plants of the new Agapanthus were more vigorous than plants of ‘PMN06’.
  • 3. Plants of the new Agapanthus had shorter and narrower leaves than plants of ‘PMN06’.
  • 4. Plants of the new Agapanthus had shorter scapes than plants of ‘PMN06’.
  • 5. Plants of the new Agapanthus had smaller flowers than plants of ‘PMN06’.
  • 6. Plants of the new Agapanthus flowered earlier than plants of ‘PMN06’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the early spring (November) in 17.5-cm containers in a outdoor nursery in Pine Mountain, Queensland, Australia and under cultural practices typical of commercial Agapanthus production. During the production of the plants, day temperatures ranged from 3° C. to 38° C., night temperatures ranged from 3° C. to 27° C. and light levels ranged from 40 to 50 klux. Plants were one year old when the photographs and description were taken.
