USPP16902P3 - Nemesia plant named ‘Pensky’ - Google Patents

Abstract

A new and distinct cultivar of Nemesia plant named ‘Pensky’ that is characterized by a compact habit, dense upright spikes of blue-purple flowers and oval shaped green leaves. In combination these characteristics set ‘Pensky’ apart from all other existing varieties of Nemesia known to the inventor.

Description

Genus: Nemesia.

Species: fruticans.

Denomination: Pensky.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant that will be referred to hereinafter by the cultivar name ‘Pensky’.

‘Pensky’ was discovered by the inventor in 2000 at the inventor's nursery in Netherwent, Wales, United Kingdom. ‘Pensky’ was first observed on a single plant of the inventor's variety of Nemesia named ‘Pengoon’ (U.S. Plant Pat. No. 14,261) in the form of a naturally occurring branch sport which carried lighter-colored flowers than are typical of ‘Pengoon’.

‘Pensky’ and ‘Pengoon’ distinguished from other Nemesias known to the inventor by their compact habit, upright flower spikes, leaves that are more oval in shape, and with thicker tissue.

When compared with the sport parent Nemesia ‘Pengoon’, ‘Pensky’ differs only in respect of the color of its flowers and flower parts. In overall appearance, ‘Pensky’ exhibits soft pale lavender blue flowers whereas ‘Pengoon’ exhibits mid blue flowers. Upon closer examination, the coloration of the palate of the flower of ‘Pensky’ is white with a dark blue margin, whereas the coloration of the palate of the flower of ‘Pengoon’ is red-purple.

‘Pensky’ was first asexually propagated by the inventor at the inventor's nursery in Netherwent, Wales, United Kingdom in 2000 by direct rooting of the single branch that had been observed. ‘Pensky’ has subsequently be asexually propagated, using tip and branch cuttings, and has been determined to reproduce true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Pensky’. In combination these traits set the new cultivar apart from all other existing varieties of Nemesia known to the inventor. ‘Pensky’ has not been tested under all possible conditions and phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions, however, without any variance in genotype.

• • 1. Nemesia ‘Pensky’ exhibits a compact habit.
  • 2. Nemesia ‘Pensky’ exhibits pale soft lavender-blue flowers.
  • 3. Nemesia ‘Pensky’ exhibits upright flower spikes.
  • 4. Nemesia ‘Pensky’ is floriferous and exhibits large, repeat-flowering heads.
  • 5. Nemesia ‘Pensky’ is hardy to USDA Zone 7.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the distinguishing traits and overall appearance of the new Nemesia cultivar ‘Pensky’. The plant photographed is one year old, and has been grown to flowering in a 1 gallon container outdoors in Santa Barbara County, Calif.

The drawing labeled as FIG. 1 illustrates the entire plant.

The drawing labeled as FIG. 2 presents, on the left side, a close-up view of the flowers of ‘Pensky’ and on the right side a hand-held group of flowers taken from a plant of ‘Pengoon’. The drawings were made using conventional photographic techniques and the laser copies were made using standard techniques. Although colors may appear different from actual colors due to light reflectance, they are as accurate as possible by conventional photography and laser copying.

BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of the Nemesia plant named ‘Pensky’. Data was collected in Arroyo Grande, Calif. from plants grown in two-gallon containers under greenhouse conditions. Phenotypic differences may be observed with variations in environmental, climatic, and cultural conditions. The color determinations are in accordance with The Royal Horticultural Society Colour Chart except where general color terms of ordinary dictionary significance are used. The growing requirements are similar to other Nemesia plants.
