plant named ‘Lundy’

Abstract

A new and distinct cultivar of Potentilla plant named ‘Lundy’, characterized by its compact, upright and outwardly spreading plant habit; freely branching habit, dense and bushy plant form; dark green-colored leaves; large dark yellow-colored flowers; long flowering period; and good garden performance.

Description

Botanical designation: Potentilla fruticosa.

Cultivar denomination: ‘LUNDY’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Potentilla plant, botanically known as Potentilla fruticosa and hereinafter referred to by the name ‘Lundy’.

The new Potentilla plant is a product of a planned breeding program conducted by the Inventor in Grand Haven, Mich. The objective of the breeding program was to develop new uniform Potentilla plants with attractive flower color.

The new Potentilla plant originated from an open-pollination during the summer of 1999 of Potentilla fruticosa ‘Hopley's Orange’, not patented, as the female, or seed, parent with an unknown selection of Potentilla fruticosa as the male, or pollen, parent. The new Potentilla plant was discovered and selected by the Inventor during the summer of 2006 as a flowering plant within the progeny of the stated open-pollination in a controlled environment in Grand Haven, Mich.

Asexual reproduction of the new Potentilla plant by softwood cuttings in a controlled environment in Grand Haven, Mich. since July, 2006, has shown that the unique features of this new Potentilla plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Potentilla have been observed under all possible cultural and environmental conditions. The phenotype may vary somewhat with variations in cultural practices and environment such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Lundy’. These characteristics in combination distinguish ‘Lundy’ as a new and distinct Potentilla plant:

• • 1. Compact, upright and outwardly spreading plant habit.
  • 2. Freely branching habit, dense and bushy plant form.
  • 3. Dark green-colored leaves.
  • 4. Large dark yellow-colored flowers.
  • 5. Long flowering period.
  • 6. Good garden performance.

Plants of the new Potentilla can be compared to plants of the parent, ‘Hopley's Orange’. Plants of the new Potentilla differ primarily from plants of ‘Hopley's Orange’ in the following characteristics:

• • 1. Plants of the new Potentilla have larger flowers than plants of ‘Hopley's Orange’.
  • 2. Plants of the new Potentilla and ‘Hopley's Orange’ differ in flower color as plants of ‘Hopley's Orange’ have orange-colored flowers.

Plants of the new Potentilla can be compared to plants of the Potentilla ‘Goldfinger’, not patented. In side-by-side comparisons, plants of the new Potentilla differ primarily from plants of ‘Goldfinger’ in the following characteristics:

• • 1. Plants of the new Potentilla are more compact than plants of ‘Goldfinger’.
  • 2. Plants of the new Potentilla have darker green-colored leaves than plants of ‘Goldfinger’.
  • 3. Plants of the new Potentilla have larger flowers than plants of ‘Goldfinger’.

Plants of the new Potentilla can also be compared to plants of the Potentilla ‘Fargo’, not patented. In side-by-side comparisons, plants of the new Potentilla differ primarily from plants of ‘Fargo’ in the following characteristics:

• • 1. Plants of the new Potentilla have darker green-colored leaves than plants of ‘Fargo’.
  • 2. Plants of the new Potentilla have larger flowers than plants of ‘Fargo’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Potentilla plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type.

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Potentilla plant.

The photograph on the first sheet comprises a side perspective view of typical flowering plants of ‘Lundy’ grown in an outdoor nursery.

The photograph on the second sheet is a close-up view of a typical flowering plant of ‘Lundy’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown during the spring and summer in an outdoor nursery in Grand Haven, Mich. and under conditions which closely approximate commercial Potentilla production. Plants were four years old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 2001 Edition, except where general terms of ordinary dictionary significance are used.
