plant named ‘Lansabine’

Abstract

A new cultivar of Hibiscus named ‘Lansabine’, characterized by its large flowers that are round in shape and “chiffon” pink in color, its short leaf internode lengths, its very dark green foliage, and its good self-branching habit.

Description

Botanical classification: Hibiscus rosa-sinensis.

Cultivar designation: ‘Lansabine’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Hibiscus plant of hybrid origin, botanically known as Hibiscus rosa-sinensis ‘Lansabine’ and will be referred to hereafter by its cultivar name, ‘Lansabine’. ‘Lansabine’ is a new cultivar of tropical Hibiscus grown for use as a landscape and container plant.

The new cultivar was developed through an on-going breeding program conducted by the Inventor in Malause, France. The objectives of the breeding program are to develop new cultivars of Hibiscus that exhibit compact plant habits with self-branching and a well-balanced plant habit.

The Inventor made a cross in July of 2005 between ‘Nelly Rose Clair’ (not patented) as the female parent and ‘Mercedes’ (not patented) as the male parent. ‘Lansabine’ was selected as a single unique plant from the resulting seedlings in September of 2009.

Asexual propagation of the new cultivar was first accomplished by stem cuttings in Malause, France in September of 2009 by the Inventor. Asexual propagation by stem cuttings has determined that the characteristics of the new cultivar are 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 ‘Lansabine’. These attributes in combination distinguish ‘Lansabine’ as a new and distinct cultivar of Hibiscus.

• • 1. ‘Lansabine’ exhibits large flowers that are round in shape and “chiffon” pink in color.
  • 2. ‘Lansabine’ exhibits short leaf internode lengths.
  • 3. ‘Lansabine’ exhibits very dark green foliage.
  • 4. ‘Lansabine’ exhibits good self-branching.

Both the female parent of ‘Lansabine’, ‘Nelly Rose Clair’, and the male parent, ‘Mercedes’, differ from ‘Lansabine’ in having flowers that are darker pink in color, in having a more vigorous growth habit, and in having longer stems with less self-branching. ‘Lansabine’ can also be most closely compared to the cultivars ‘Bellona’ (not patented) and ‘Cancun’ (not patented). Both are similar to ‘Lansabine’ in having flowers that are pink in color. ‘Bellona’ differs from ‘Lansabine’ in having flowers that are darker pink in color with a black eye zone and in having stems with less self-branching and longer leaf internodes. ‘Cancun’ differs from ‘Lansabine’ in having smaller flowers with a red eye zone.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying colored photograph illustrates the overall appearance and distinct characteristics of the new Hibiscus. The photographs were taken of a six month-old plant of ‘Lansabine’ as grown in a one-gallon container in a greenhouse in Malause, France.

The photograph in FIG. 1 provides a side view of ‘Lansabine’ in bloom.

The photograph in FIG. 2 provides a close-up view of a flower of ‘Lansabine’.

The colors in the photographs are as close as possible with the digital photography and printing techniques utilized and the color codes in the detailed botanical description accurately describe the new Hibiscus.
