USPP20268P2 - Nemesia plant named ‘Pendrop’ - Google Patents

Abstract

A new and distinct cultivar of Nemesia plant named ‘Pendrop’ that is characterized by a compact habit, pale green foliage, short stems, and purple and white flowers with a prominent yellow palate. In combination, these characteristics set ‘Pendrop’ apart from all other existing varieties of Nemesia known to the inventor.

Description

Genus: Nemesia.

Species: ×hybrida.

Denomination: ‘Pendrop’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Nemesia plant that is grown as an ornamental plant for use in a border, patio container or hanging basket. The new cultivar is known botanically as Nemesia×hybrida and will be referred to hereinafter by the cultivar name ‘Pendrop’.

The new Nemesia variety named ‘Pendrop’ is the product of a breeding program established by the inventor in 2001 at the inventor's nursery in Netherwent, Wales, United Kingdom. The purpose of the breeding program is to produce new compact sterile Nemesia varieties with a high ratio of flower to leaf.

‘Pendrop’ is a seedling selection arising from the inventor's crossing of own parent lines which were never released as commercial varieties or patented. ‘Pendrop’ was selected in 2002 for its floriferousness, sterile flowers, very compact habit and attractive bi-colored flowers.

In order to achieve the desired combination of sterility and compactness of a new variety of Nemesia, the inventor chose parents (from his previously-raised seedlings) which were barely fertile and also naturally compact. Both of the parents of ‘Pendrop’ possessed a short growth habit. One parent bore entirely pink flowers. The other parent bore flowers which were bi-colored pink and yellow and also exhibited larger leaves than ‘Pendrop’. Neither parent exhibited the characteristic prominent yellow palate of ‘Pendrop’.

The closest commercial variety known to the inventor is the inventor's variety Nemesia ‘Pengoon’ (U.S. Plant Pat. No. 14,261). In comparison to ‘Pengoon’, ‘Pendrop’ is more compact and has bi-colored flowers; the flowers of ‘Pengoon’ are uniformly blue in color.

‘Pendrop’ was first asexually propagated by the inventor at the inventor's nursery in Netherwent, Wales, United Kingdom in 2003 using tip cuttings. ‘Pendrop’ has subsequently be asexually propagated, using tip and branch cuttings, and has been determined to reproduce true to type in successive generations of asexual reproduction.

An application for European Plant Breeder Rights was filed on Oct. 25, 2005, with application number 2005/2041. The first sales or public distribution of ‘Pendrop’ occurred on Apr. 1, 2006, at the inventor's nursery in Wales, United Kingdom.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the distinguishing characteristics of ‘Pendrop’. In combination these traits set the new cultivar apart from all other existing varieties of Nemesia known to the inventor. ‘Pendrop’ 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. ‘Pendrop’ bears pale green foliage.
  • 2. ‘Pendrop’ bears purple and white flowers with a prominent yellow palate.
  • 3. ‘Pendrop’ has short stems.
  • 4. ‘Pendrop’ is compact in habit.
  • 5. ‘Pendrop’ is suitable for use as a garden or landscape plant.
  • 6. ‘Pendrop’ is hardy to USDA Zone 6.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings illustrate the distinguishing traits and overall appearance of the new Nemesia cultivar ‘Pendrop’. The plant photographed is one year old, and has been grown in an unheated greenhouse in Netherwent, Wales, United Kingdom.

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

The drawing labeled as FIG. 2 presents a close-up of the flowers.

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 ‘Pendrop’. Data was collected in Cambridgeshire, United Kingdom from plants grown in 9 cm 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.
