Abstract

A new and distinct cultivar of Ajuga reptans plant named ‘ABFG0413A’ is disclosed, characterized the unique combination of bronze/purple foliage with a purple flower. The new variety is a Ajuga, plants are useful for a variety of ornamental purposes, including outdoor containers and landscape.

Description

Latin name of the genus and species: Ajuga reptans.

Variety Denomination: ‘ABFG0413A’.

BACKGROUND OF THE INVENTION

The new Ajuga cultivar is the product of chance discovery. The new variety was discovered as a spontaneous seedling of unknown parentage. The discovery was made in at the inventor's home garden.

The discovery was made in the inventor's garden in Bressingham, England, during March of 2014.

Asexual reproduction of the new cultivar ‘ABFG0413A’ was first performed in Bressingham, England, by terminal vegetative cuttings in Spring of 2014. ‘ABFG0413A’ has since produced multiple generations and has shown that the unique features of this cultivar are stable and reproduced true to type.

SUMMARY OF THE INVENTION

The cultivar ‘ABFG0413’ 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 ‘ABFG0413A’ These characteristics in combination distinguish ‘ABFG0413A’ as a new and distinct Ajuga reptans cultivar:

- 1. Purple flower color in combination with a bronze-purple leaf.

PARENTAL COMPARISON

The parentage is unknown.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘ABFG0413A’ are comparable to the well-known commercial variety, Ajuga ‘Mahogany’, unpatented. Plants are similar in most horticultural characteristics; however, the new variety ‘ABFG0413A’ differs in the following:

- 1. Flowers of the new variety are purple; flowers of this comparator are blue.
- 2. Foliage of the new variety is narrower than foliage of this comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photograph in FIG. 1 illustrates in full color a typical plant of ‘ABFG0413A’ grown outdoors in Bressingham, England. Age of the plant is approximately 8 months.

FIG. 2 illustrates a closer view of the foliage and flowers.

The photographs were taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques. No artificial light, photoperiodic treatments or chemical treatments were given to the plants.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 except where general terms of ordinary dictionary significance are used.
