USPP24734P2 - Alonsoa plant named ‘PENSCAR’ - Google Patents

Abstract

A new and distinct cultivar of Alonsoa plant named ‘PENSCAR’ that is characterized by a compact and upright habit, green and white-cream variegated leaves, and bright scarlet single flowers. In combination these traits set ‘PENSCAR’ apart from all other existing varieties of Alonsoa known to the inventor.

Description

Genus: Alonsoa.

Species: ×meridionalis.

Denomination: ‘PENSCAR’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Alonsoa, which is grown as an ornamental tender perennial plant for use in the garden and landscape. The new cultivar is known botanically as Alonsoa×meridionalis, and will be referred to hereinafter by the cultivar name ‘PENSCAR’. ‘PENSCAR’ was discovered by the inventors in 2007 as a naturally occurring variegated branch sport. The branch sport was observed on a single plant in a seed-raised crop of Alonsoa×meridionalis (species, unpatented) growing in the inventors' nursery in Caldicot, Monmouthshire, United Kingdom.

‘PENSCAR’ exhibits a compact upright habit, prominently variegated and serrated leaves and bright scarlet flowers. ‘PENSCAR’ grows to 70 cm. in height and 40 cm. in width during a one year growing season. ‘PENSCAR’ exhibits its distinguishing characteristics to best effect when grown in full sun or light shade, with moderate water. There are no particular pests or diseases known to the inventor which affect ‘PENSCAR’. ‘PENSCAR’ is hardy to at least in USDA Zone 9.

The closest comparison plant known to the inventor is the non-variegated parent variety, a seed-raised plant of the species Alonsoa×meridionalis. ‘PENSCAR’ is distinguishable from the comparison plant by its variegated leaves. In other respects, including the bright scarlet flowers, ‘PENSCAR’ is indistinguishable from its parent.

‘PENSCAR’ was first asexually propagated by the inventors in April 2007 in Caldicot, Monmouthshire, United Kingdom. Asexual propagation was accomplished using tip cuttings. Since that time, under careful observation, the distinguishing characteristics of ‘PENSCAR’ have been determined stable and uniform, and to reproduce true to type in successive generations of asexual propagation.

The inventors filed an application for European Community Plant Breeders' Rights for ‘PENSCAR’ on Oct. 29, 2010, Serial Number 2010/2161. At the time of filing the application for European Community Plant Breeders' Right cited above, and until February 2011, all plants of ‘PENSCAR’ remained at the inventors' nursery under the inventors' control. The first public distribution of any plants of ‘PENSCAR’ took place in February 2011 when the inventors commenced deliveries of plants to wholesale growers in the United Kingdom.

SUMMARY OF THE INVENTION

The distinguishing characteristics of ‘PENSCAR’ are as follows: In combination these traits set ‘PENSCAR’ apart from all other existing varieties of Alonsoa known to the inventors. ‘PENSCAR’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions.

• • 1. Plants of ‘PENSCAR’ exhibit a compact and upright growth habit.
  • 2. The leaves of ‘PENSCAR’ are variegated.
  • 3. The leaves of ‘PENSCAR’ are predominantly mid-green in color, with contrasting white to cream margins.
  • 4. ‘PENSCAR’ bears bright scarlet single flowers.
  • 5. After one year of unrestricted growth, plants of ‘PENSCAR’ are 70 cm in height and 40 cm in width.
  • 6. ‘PENSCAR’ prefers full sun in rich well-drained soil.
  • 7. ‘PENSCAR’ is a tender perennial which survives in USDA Zone 9 or warmer.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of ‘PENSCAR’ showing the colors of its foliage and flowers as true as it is reasonably possible to obtain in colored reproductions of this type.

The drawings were made from one year old plants of ‘PENSCAR’ which were photographed in the fall at the inventors' nursery in Caldicot, Monmouthshire, United Kingdom.

The drawing labeled FIG. 1 depicts an entire flowering plant of ‘PENSCAR’.

The drawing labeled FIG. 2 depicts a close-up view of the flowers of ‘PENSCAR’.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of the new Alonsoa cultivar named ‘PENSCAR’. Observations, measurements, values and comparisons were collected from a plant grown out-of-doors in Santa Barbara, Calif. The observed plant was approximately nine months old and was growing in a 1 gallon container. The plant had been grown without the use of growth retardant chemicals or any pinching. Color determinations were made in accordance with The 2001 Royal Horticultural Society Colour Chart from London, England, except where general color terms of ordinary dictionary significance are used. The growing requirements of the new variety ‘PENSCAR’ are similar to the species.
