Abstract
A new and distinct cultivar of Ajuga named ‘Black Scallop’ that is characterized by dense compact habit, large round dark maroon-purple leaves and fragrant dark violet flowers. In combination these traits set ‘Black Scallop’ apart from all other existing varieties of Ajuga known to the inventor.
Description
Genus: Ajuga.
Species: reptans.
Denomination: Black Scallop.
The present invention relates to a new and distinct cultivar of carpet bugle that is grown for use as an ornamental groundcover for the landscape. The new cultivar is known botanically as Ajuga reptans and will be referred to hereinafter by the cultivar name ‘Black Scallop’.
For approximately eight years prior to the selection of ‘Black Scallop’ as described below, the inventor had grown for sale as one year old plants the dark-leaved Ajuga reptans variety known as ‘Braunherz’ (unpatented). In common with inventor's commercial practice, in order to obtain and maintain a reliable source of clean stock plants of ‘Braunherz’, the inventor had established plants of ‘Braunherz’ in vitro in the inventor's nursery laboratory. In 1998, the inventor observed a single plant within a batch of plants that had been grown in pots in soil-based medium from the inventor's in vitro ‘Braunherz’ material. This single plant, ‘Black Scallop’, was a naturally occurring whole plant mutation that exhibited novel and attractive foliage characteristics which the inventor considered set it apart from ‘Braunherz’ and from other varieties of Ajuga known to the inventor. The inventor isolated, and in 2000 first asexually reproduced ‘Black Scallop’ using basal shoot cuttings. All of the resulting plants were grown to maturity and the inventor determined that ‘Black Scallop’ had remained stable and true to type. ‘Black Scallop’ has remained stable and true to type through subsequent generations of asexual reproduction.
‘Black Scallop’ is a perennial ground cover with dark violet flowers and a mat of dark maroon-purple leaves. The parent plant is Ajuga reptans' ‘Braunherz’ which is considered by the inventor to be the closest comparison plant to ‘Black Scallop’. The foliage of ‘Black Scallop’ is larger and rounder and more uniformly dark than other medium-sized cultivars of dark-leaved Ajuga known to the inventor, including ‘Braunherz’. The foliage of ‘Black Scallop’ is smaller than the large-sized cultivars of bronze-green-leaved Ajuga known to the inventor, including the cultivar Ajuga ‘Catlin's Giant’ (unpatented) which is typical of the type. When compared with ‘Braunherz’, ‘Black Scallop’ exhibits larger flowers and the whole plant exhibits greater heat tolerance, and greater resistance to powdery mildew.
The following traits have been repeatedly observed and represent the distinguishing characteristics of the new Ajuga cultivar ‘Black Scallop’. These traits in combination, distinguish ‘Black Scallop’ from all other varieties of Ajuga known to the inventor. ‘Black Scallop’ has not been tested under all possible conditions. Phenotypic differences might occur with variations in environmental, climatic, and cultural conditions without any variance in genotype.

- 8. The new Ajuga cultivar ‘Black Scallop’ exhibits large dark violet flowers from spring to early summer.
- 9. The new Ajuga cultivar ‘Black Scallop’ exhibits short flower stalks that produce inflorescences borne above the foliage.
- 10. A mature (second season) plant of the new Ajuga cultivar ‘Black Scallop’ measures 30 cm to 40 cm in width and approximately 20 cm in height when grown in the ground or in a 2-liter container.
- 11. The new Ajuga cultivar ‘Black Scallop’ is hardy to USDA Zone 6.
- 12. The new Ajuga cultivar ‘Black Scallop’ is propagated by tip cuttings and division.
The accompanying color drawings illustrate the overall appearance of the new Ajuga cultivar ‘Black Scallop’, showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘Black Scallop’.
The drawings are made using conventional photographic techniques and although flower and foliage colors in the photographs may differ from the actual colors due to light reflectance, they are as accurate as conventional photography can portray.
The following is a detailed botanical description of the new Ajuga cultivar ‘Black Scallop’. Observations, measurements, values and comparisons were collected in Arroyo Grande, Calif. from plants in their second season of growth in 2-liter containers that were grown out-of-doors in a frost-free environment. Color determinations are made in accordance with 2001 Edition of the Colour Chart of The Royal Horticultural Society, London England, except where general color terms of ordinary dictionary significance are used. The growing requirements of the new variety are similar to the species and there are no growing problems known to the inventor.
