plant named ‘KEK 5006’

Abstract

A new and distinct Agapanthus cultivar named ‘KEK 5006’ is disclosed, characterized by, green foliage with a distinct yellow margin. Plants are consistently variegated and easier to propagate than most variegated Agapanthus. The new variety is a Agapanthus, typically produced as an outdoor ornamental plant.

Description

Latin name of the genus and species: Agapanthus praecox.

Variety denomination: ‘KEK 5006’.

BACKGROUND OF THE INVENTION

The new cultivar is the product of chance discovery. The new variety originated as a naturally occurring, whole plant mutation of an unpatented, unnamed Agapanthus praecox.

The new variety was discovered by the inventor after several years of isolating and propagating clones of the interesting Agapanthus praecox mutation in a commercial nursery in Lanseria, South Africa. After identifying the new variety as a potentially interesting selection, the inventor continued confidential testing and observation of ‘KEK 5006’ until approximately 1997, finally selecting the variety ‘KEK5006’ for further propagation during 2000.

Asexual reproduction of the new cultivar ‘KEK 5006’ was first performed by division in Lanseria, South Africa, during 2000, on a very limited basis. Access to all plants was restricted, as plants were kept in a location not open to the public. Through subsequent propagation, multiple generations have been reproduced, which have shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘KEK 5006’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘KEK 5006’. These characteristics in combination distinguish ‘KEK 5006’ as a new and distinct Agapanthus cultivar:

• • 1. Broad, variegated foliage.
  • 2. Very stable variegation, without reversion.
  • 3. Faster growing than typical variegated Agapanthus.
  • 4. Green foliage with a bright yellow margin.

PARENT COMPARISON

Plants of the new cultivar ‘KEK 5006’ are similar to the parent in most horticultural characteristics. However, the new variety, produces very stable variegated foliage, compared to the parent plant, which reverts more easily. Additionally, plants of ‘KEK 5006’ produce flowers of a lighter blue than the parent variety.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘KEK 5006’ are similar to the unpatented commercial variety Agapanthus praecox ‘Tinkerbell’ in most horticultural characteristics. The new variety, however, differs in the following:

• • 1. Produces foliage that is green with yellow variegation, whereas ‘Tinkerbell’ produces silver-green variegated leaves.
  • 2. ‘KEK 5006’ consistently produces flowers regularly whereas ‘Tinkerbell’ flowers infrequently and erratically. Foliage of the new variety is broader than foliage of ‘Tinkerbell’.
  • 3. Broader foliage than ‘Tinkerbell’.
  • 4. Flowers of the new variety produce a lighter color blue than flowers of ‘Tinkerbell’.
  • 5. Plants of the new variety are on average 20 cm taller.

Plants of the new cultivar ‘KEK 5006’ are similar to the commercial variety Agapanthus africanus ‘Summer Gold’, unpatented, in most horticultural characteristics. The new variety, however, differs in the following:

• • 1. Plants of the new variety are taller than plants of ‘Summer Gold’.
  • 2. Flowers of the new variety produce a much lighter color blue than flowers of ‘Summer Gold’.
  • 3. Plants of the new variety have a lighter yellow variegation
  • 4. Plants of the new variety are easier to propagate than plants of ‘Summer Gold’.
  • 5. Foliage of the new variety is much broader than foliage of ‘Summer Gold’.
