Sedum plant named ‘Postmans Pride’

Abstract

A new cultivar of Sedum plant named ‘Postmans Pride’ that is characterized by a compact upright bushy habit and thick succulent very dark brown leaves. In combination these traits set ‘Postmans Pride’ apart from all other existing varieties of Sedum known to the inventor.

Description

Genus: Sedum.

Species: ×hybrida.

Denomination: Postmans Pride.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Sedum grown as an ornamental for use in container or landscape. The new cultivar is known botanically as Sedum×hybrida and will be referred to hereinafter by the cultivar name ‘Postmans Pride’.

In summer 1999, the inventor carried out at his residence in Bassevelde, Belgium a controlled hybridization between Sedum ‘Lynda et Rodney’ (unpatented) as female parent and Sedum ‘Purple Emperor’ (unpatented) as male parent. Seeds resulting from this cross were collected during fall 1999 and sown immediately. From the resulting seedling population, the inventor removed and isolated ‘Postmans Pride’ as a single plant which appeared to exhibit distinctly dark brown foliage when compared with either of the parent cultivars or any other variety of Sedum known to inventor. The inventor allowed this single plant to grow until spring 2002 in order to determine whether the overall habit of ‘Postmans Pride’ was commercially acceptable. During 2002, the inventor determined that ‘Postmans Pride’ exhibits unique and valuable characteristics. The inventor commenced asexual reproduction using internodal stem cuttings with one leaf attached. The inventor has confirmed that all plants thus propagated have remained stable and true to the characteristics of the original seedling selected as ‘Postmans Pride’. These initial and subsequent reproductions and determinations were carried out by the inventor at the inventor's nursery in Bassevelde, Belgium.

‘Postmans Pride’ is characterized by compact, bushy habit, very dark brown succulent leaves, and flowers that are grey-purple and yellow-green in color.

When compared with the female parent plant, Sedum ‘Lynda et Rodney’, ‘Postmans Pride’ exhibits a more erect plant habit without any tendency to “fall apart” as the plant matures. The inventor has observed this tendency in many dark-leaved selections of Sedum.

When compared with the male parent plant, Sedum ‘Purple Emperor’, ‘Postmans Pride’ exhibits a more consistent and uniform dark brown coloration to the foliage whereas the foliage of ‘Purple Emperor’ has been observed to “green up” especially in conditions of shade.

Other than the parental cultivars compared above, the only other cultivar of dark-leaved Sedum known to the inventor is the Sedum plant known as ‘Lynda Windsor’ (unpatented). Whereas ‘Lynda Windsor’ achieves a height of 25 cm in one growing season, with average internodes of 4.5 cm, ‘Postmans Pride’ achieves a height of 20 cm, with average internodes of 2.5 cm.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new Sedum cultivar ‘Postmans Pride’. These traits in combination distinguish ‘Postmans Pride’ from all other commercial varieties known to the inventor. ‘Postmans Pride’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic and cultural conditions.

  • 4. Sedum ‘Postmans Pride’ exhibits short strong flower stems.
  • 5. Sedum ‘Postmans Pride’ is resistant to mildew.
  • 6. Sedum ‘Postmans Pride’ is hardy to USDA Zone 4.
  • 7. Sedum ‘Postmans Pride’ is propagated using stem cuttings.
  • 8. Sedum ‘Postmans Pride’ is an ornamental suitable for landscape and container.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying color drawings illustrate the overall appearance of ‘Postmans Pride’ showing the colors as true as 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 ‘Postmans Pride’.

The drawing labeled as FIG. 1 illustrates a close up view of the inflorescence of ‘Postmans Pride’.

The drawing labeled as FIG. 2 illustrates a close up view of a single leaf of ‘Postmans Pride’.

The drawing labeled as FIG. 3 illustrates the entire one year growth of a single plant of ‘Postmans Pride’.

The drawings were made in Boskoop, The Netherlands 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 botanical description of ‘Postmans Pride’ using data collected from a plant of ‘Postmans Pride’ during its first full year of growth. The plant was started from a cutting in fall 2003 and grown to maturity and seed set in fall 2004. The plant was grown outdoors without protection in Boskoop, The Netherlands. The color determinations are in accordance with the 2001 Royal Horticultural Society Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used. The plant did not receive any chemical treatments. Growing conditions, diseases and pests are similar to that of other Sedum. There are no growing problems known to the inventor.
