Diascia plant named ‘PENDER’

Abstract

A new cultivar of Diascia plant named ‘PENDER’ that is characterized by compact habit, green leaves, and flowers that are deep salmon-pink in color. In combination these traits set ‘PENDER’ apart from all other existing varieties of Diascia known to the inventor.

Description

Genus: Diascia. Species:×hybrida.

Denomination: ‘PENDER’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of twinspur, a perennial that is grown for use in raised beds, borders, hanging baskets, and patio containers. The new cultivar is known botanically as Diascia and will be referred to hereinafter by the cultivar name ‘PENDER’.

The inventor has been interested and has collected plants of the genus Diascia since the early 1990s. Diascia, which is native to southern Africa, provides showy annual and perennial (in mild climates) plants whose predominant flower color range in nature is in the range of soft to dark pink, also white, lavender-pink, salmon and apricot. Plants of Diascia which are raised from seed are inherently variable in growth habit, ranging from loose, weak plants with brittle stems to plants with significantly shorter internodes resulting in more compact forms and therefore more dense flowering characteristics. Various breeding programs, including the inventor's , have aimed to develop improvements in plant habit and also an extension in the color range into deep pink or red or orange shades and ideally with very similar compact habits for each color.

In 1995, the inventor commenced a deliberate program to develop a range of Diascias whose characteristics would be common throughout, namely an extremely compact plant habit with bright flower colors, and in a range of colors. In 1995 the inventor selected from his collection several plants with the dwarfest habit and hand-pollinated amongst them. The plants involved in the hybridization are unknown although some were numbered selections from prior work.

The seedlings raised during 1995 flowered in the same year and many were retained for further observation in 1996 and 1997. In May 1997, the inventor determined that one plant, PENDAN (unpatented), exhibited exceptional characteristics of dense mounding habit and bright clear saturated pink flowers.

The new Diascia, PENDER was selected in summer of 2002 as a naturally occuring sport found by the inventor to be growing amongst a block of mother plants of PENDAN. The mother plants of PENDAN were all in flower and were growing in 5 liter containers in the inventor's greenhouse in Penhow, Newport, Wales, United Kingdom. Although PENDER exhibited the same overall habit and density of flowering as PENDAN, the inventor was able to distinguish PENDER by its significantly different deep salmon-pink flowers. The inventor considers that the combination of deep salmon-pink flowers and dense mounding habit sets PENDER apart from other cultivars of Diascia known to the inventor.

The distinguishing characteristics of ‘PENDER’ are compact habit, green leaves, and flowers that are deep salmon-pink in color. The flowers of ‘PENDER’ bloom profusely spring, summer, and fall. The parent Diascia ‘PENDAN’ is the closest comparison plant. The new Diascia cultivar ‘PENDER’ is distinguishable from the parent ‘PENDAN’ solely by flower colors which are deep salmon-pink and mid pink respectively. In all other traits the two plants are identical.

The first asexual propagation of the new Diascia cultivar ‘PENDER’ was conducted in 2003 by the inventor at his nursery in Newport, Gwent, England. The method of asexual propagation used was vegetative tip cuttings. Since that time the unique and distinguishing characteristics of ‘PENDER’ have been determined stable, fixed, and reproduce true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Diascia cultivar ‘PENDER’. These traits in combination distinguish ‘PENDER’ from all other commercial varieties of Diascia known to the inventor. ‘PENDER’ 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. ‘PENDER’ exhibits compact habit.
  • 2. ‘PENDER’ exhibits flowers that are deep salmon-pink in color.
  • 3. ‘PENDER’ blooms profusely spring, summer, and fall.
  • 4. ‘PENDER’ exhibits green leaves.
  • 5. ‘PENDER’ is propagated using the method of vegetative tip cuttings.
  • 6. ‘PENDER’ is 25 cm. in height and 62 cm. in width in a 5 liter container.
  • 7. The cultural requirements of ‘PENDER’ are well-draining soil, full sun, and regular water.
  • 8. ‘PENDER’ is suitable for use in raised beds, borders, hanging baskets, and patio containers.
  • 9. ‘PENDER’ is hardy to USDA Zone 7.

BRIEF SUMMARY OF THE DRAWINGS

The accompanying color drawings FIG. 1 and FIG. 2 illustrate the overall appearance of the new Diascia cultivar ‘PENDER’ showing colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in FIG. 1 and FIG. 2 may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety of Diascia named ‘PENDER’.

The drawing labeled as FIG. 1 depicts, in the foreground, three whole plants of ‘PENDER’ in full bloom illustrating habit and deep salmon-pink flower color. Behind the three plants of ‘PENDER’ are lined up four plants of the parent PENDAN’. This drawing illustrates the very similar habits of ‘PENDER’ and ‘PENDAN’ and the differing flower colors of deep salmon-pink and mid pink respectively. The illustrated plants have all been grown in 5 liter containers in the inventor's greenhouse in Newport, Wales, United Kingdom. The parts of plants with white and blue flowers which are present in the front right corner of the drawing are extraneous. The partially grown plants in the very background of the drawing are also extraneous.

The drawing labeled as FIG. 2 illustrates a close up of a typical inflorescence of ‘PENDER’ and the characteristic deep salmon-pink of the flower color.

Both the drawings were made using conventional photographic techniques. 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 the new Diascia cultivar ‘PENDER’. Data was collected June 2005 in Arroyo Grande, Calif. from 18 month old plants growing in 5 liter containers. The color determinations are in accordance with the 2001 edition of The Royal Horticultural Society Colour Chart, except where general color terms of ordinary dictionary significance are used. The new Diascia variety named ‘PENDER’ has not been observed under all possible environmental conditions. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, without however, any difference in genotype.
