plant named ‘LISSDAN’

Abstract

A new cultivar of Dasiphora, ‘LISSDAN’, that is characterized by its upright, bushy plant form, its single flowers with the upper surface of the petals bright cerise to fuchsia pink in color and the lower surface of the petals pale cream to parchment in color, and its flowers that retain their color throughout the blooming season.

Description

Botanical classification: Dasiphora fruticosa subsp. fruiticosa.

Variety denomination: ‘LISSDAN’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Dasiphora fruticosa subsp. fruiticosa (syn. Potentilla fruticosa). The new cultivar will be referred to hereafter by its cultivar name, ‘LISSDAN’. ‘LISSDAN’ is a new cultivar of deciduous shrub grown for landscape use.

‘LISSDAN’ was discovered by the Inventor as a chance seedling in his garden in Eccleshall, Stafford, United Kingdom in 2007. The parentage is unknown.

Asexual propagation of the new cultivar was first accomplished by softwood cuttings under the direction of the Inventor in Greatham, Hampshire, The United Kingdom in spring of 2008. Asexual propagation by softwood cuttings has determined that the characteristics of the new cultivar are stable and 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 shrub rose. These attributes in combination distinguish ‘LISSDAN’ as a unique cultivar of Dasiphora.

• • 1. ‘LISSDAN’ exhibits an upright and bushy plant habit.
  • 2. ‘LISSDAN’ exhibits single flowers with the upper surface of the petals bright cerise to fuchsia pink in color and the lower surface of the petals pale cream to parchment in color.
  • 3. ‘LISSDAN’ is exhibits flowers that retain their coloration late in the blooming season.

‘LISSDAN’ can be most closely compared to the Dasiphora cultivars ‘Marrob’ (not patented) and ‘Red Ace’ (U.S. Plant Pat. No. 4,226). ‘Marrob’ differs from ‘LISSDAN’ in having an irregular, lax and less upright plant habit, in having flowers with petals that are orange-red in color and fade to a dull orange on the upper surface and pale green to beige in color on the lower surface. ‘Red Ace’ differs from ‘LISSDAN’ in having a less upright and lax plant habit, in having flowers with petals that are less pink in color and fade to a dull orange on the upper surface and pale green to beige in color on the lower surface.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Dasiphora, ‘LISSDAN’.

The photograph in FIG. 1 was taken of a two year-old plant as grown outdoors in the ground in Greatham, Hampshire, United Kingdom.

The photographs in FIG. 2, FIG. 3, FIG. 4, and FIG. 5 were taken of two year-old plants as grown in five-liter containers in Greatham, Hampshire, United Kingdom.

The photograph in FIG. 1 provides a view of ‘LISSDAN’ in the landscape.

The photograph in FIG. 2 provides a view of a mature flower of ‘LISSDAN’ in June.

The photograph in FIG. 3 provides a view of the late season flowers and achenes of ‘LISSDAN’ in September.

The photograph in FIG. 4 provides a comparison of mature flowers of ‘Marrob’ on the left, ‘LISSDAN’ in the center, and ‘Red Ace’ on the right.

The photograph in FIG. 5 provides a comparison of the winter plant habits of ‘Red Ace’ on the left, ‘LISSDAN’ in the center, and ‘Marrob’ on the right.

The colors in the photographs are as close as possible with digital photography techniques available and the color values cited in the detailed botanical description accurately describe the colors of the new Dasiphora.

DETAILED BOTANICAL DESCRIPTION

The following is a detailed description of two year-old plants of the new cultivar as grown outdoors in five-liter containers in Greatham, Hampshire, The United Kingdom.
