plant named ‘Inov42’

Abstract

A new cultivar of Lonicera, ‘Inov42’, characterized by its foliage that is persistent, dense and evergreen in winter in France, its dense flowering display of fragrant inflorescences in June that emerge white in color with purple-red markings and turn orange as they mature, its resistance to powdery mildew, black spot, and green fly and its relatively compact vining plant habit.

Description

Botanical classification: Lonicera henryi×japonica.

Variety denomination: ‘Inov42’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Lonicera, botanically of hybrid origin, and will be referred to hereafter by its cultivar name, ‘Inov42’. ‘Inov42’ is a new cultivar of honeysuckle, a vine grown for use as an ornamental landscape plant.

The new Invention arose from an ongoing controlled breeding program in Beaucouzé, France. The Inventor made a cross in summer of 1993 between an unnamed plant of ‘Lonicera henryi’ as the female parent and Lonicera japonica ‘Aureoreticulata’ (not patented) as the male parent. ‘Inov42’ was selected from amongst the resulting seedlings as a single unique plant in June 2003.

Asexual reproduction of the new cultivar was first accomplished by the Inventor using softwood stem cuttings in April of 2004 in Beaucouzé, France. The characteristics of this cultivar have been determined to be stable and are 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 cultivar as grown outdoors in a trial plot for five years in Beaucouzé, France. These attributes in combination distinguish ‘Inov42’ as a unique cultivar of Lonicera.

• • 1. ‘Inov42’ exhibits foliage that is persistent and evergreen in winter in Beaucouzé, France.
  • 2. ‘Inov42’ exhibits abundant, fragrant flowers in June that emerge white with purple-red markings and turn orange as they mature.
  • 3. ‘Inov42’ exhibits a relatively compact vining habit of dense foliage.
  • 4. ‘Inov42’ exhibits resistance to powdery mildew, black spot, and green fly.

‘Inov42’ is unique as a hybrid between L. henryi and L. japonica and can be most closely compared to its parent plants. In comparison to the female parent, L. henryi, ‘Inov42’ differs in having more fragrant flowers, a more compact plant habit, leaves that are shorter in length, and foliage that is more persistent throughout the winter. In comparison to the male parent, L. japonica ‘Aureoreticulata’, ‘Inov42’ differs in having green persistent foliage, whereas the foliage of ‘Aureoreticulata’ is green with yellow veining and semi-persistent. ‘Inov42’ also exhibits a more compact plant habit and in having flowers with purple-red markings whereas ‘Aureoreticulata’ has flowers that lack purple-red markings. Although there are no cultivars of the same hybrid background known to the Inventor, ‘Inov42’ can be compared to plants from the same breeding program that were also selected for their compact habits and disease resistance. ‘Inov71’ (U.S. patent application Ser. No. 12/584,237) differs from ‘Inov42’ in having a more columnar habit and in having flowers that mature to a creamy yellow color rather than orange. ‘Inov86’ (U.S. patent application Ser. No. 12/584,231) differs from ‘Inov42’ in having larger flowers that open from dark purple buds and turn dark pink and white and mature to creamy yellow-orange.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photographs were taken in mid summer and illustrate the overall appearance and distinct characteristics of 5 year-old plants the new Lonicera as grown in a trial garden in Beaucouzé, France. The photograph in FIG. 1 provides an overall view of the dense, compact habit of ‘Inov42’ in bloom. The photograph in FIG. 2 provides a close-up view of the foliage of ‘Inov42’. The photograph in FIG. 3 provides a close-up view of the inflorescences of ‘Inov42’. The 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 Lonicera.
