Abstract

A new cultivar of Brugmansia plant named ‘Miner's Claim’ that is characterized by upright, spreading habit, variegated cream-white and light green foliage, and large salmon-pink flowers. In combination these traits set ‘Miner's Claim’ apart from all other existing varieties of Brugmansia known to the inventor.

Description

Genus, species: Brugmansia×hybrida.

Varietal denomination: ‘Miner's Claim’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of angels trumpet grown for use as an ornamental shrub. The new cultivar is known botanically as Brugmansia×hybrida and will be referred to hereinafter by the cultivar name ‘Miner's Claim’.

‘Miner's Claim’ was discovered as a naturally occurring branch sport in a cultivated area of Monterey, Calif. in 1999. The sport was found on one individual plant within a block of commercially produced Brugmansia ‘Frosty Pink’, and selected by the inventor for low vigor, and broadly conspicuous variegation of foliage. The parent plant is Brugmansia ‘Frosty Pink’ (unpatented). The closest comparison plant is Brugmansia ‘Frosty Pink’. ‘Miner's Claim’ is distinguishable from ‘Frosty Pink’ by conspicuous cream-white and light green marginal variegation of the foliage.

‘Miner's Claim’ is evergreen and suitable for use as an ornamental shrub. ‘Miner's Claim’ exhibits an upright, spreading habit, variegated foliage and strongly fragrant, salmon-pink flowers. The distinguishing characteristics are slow growth and variegated foliage. The cultural requirements are rich, highly amended soil and direct sunlight during half the daylight hours. When planted in complete bright shade ‘Miner's Claim’ will grow slower than its typically slow growth rate.

The first asexual reproduction of ‘Miner's Claim’ was conducted under the direct supervision of the inventor in a cultivated area of Monterey, Calif. in 2000. The method used for asexual propagation was softwood cuttings. The characteristics of the new cultivar have been determined 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 Brugmansia cultivar ‘Miner's Claim’. These traits in combination distinguish ‘Miner's Claim’ from all other commercial varieties of Brugmansia known to the inventor. ‘Miner's Claim’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions, without however, any difference in genotype.

- 1. Brugmansia ‘Miner's Claim’ exhibits an upright, spreading habit.
- 2. Brugmansia ‘Miner's Claim’ is slow-growing, exhibiting fifty-percent the vigor of its parent.
- 3. Brugmansia ‘Miner's Claim’ exhibits cream-white and light green marginal variegation of the foliage.
- 4. Brugmansia ‘Miner's Claim’ exhibits large semi-pendulous trumpet-shaped salmon-pink flowers.
- 5. Brugmansia ‘Miner's Claim’ is 3.4 meters. in width and 3.2 meters. in height at maturity.
- 6. Brugmansia ‘Miner's Claim’ is propagated by the method of softwood cuttings.
- 7. Brugmansia ‘Miner's Claim’ is suitable for use as an ornamental shrub.
- 8. With protection Brugmansia ‘Miner's Claim’ is hardy to USDA Zone 9a.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of the new variety ‘Miner's Claim’ showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the drawings may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety ‘Miner's Claim’. The plants in the drawings were grown in 5-liter containers and treated with MARATHON® insecticide.

The first drawing illustrates the entire plant, before bloom, from a side perspective.

The second drawing is a close-up view of the flower and foliage.

The drawings were made using conventional techniques and although colors may appear different from actual colors due to light reflectance they are as accurate as possible by conventional photography.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of ‘Miner's Claim’ as grown In Monterey, Calif. Data was collected from 5-liter container plants during their first season of growth, that is from 6 months to 9 months (in flower) from a cutting. The color determinations are in accordance with the 2001 Edition of the Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. Growing conditions, diseases and pests are similar to that of other Brugmansia. There are no growing problems known to the inventor.
