plant named ‘EARLY NIR’

Abstract

A new and distinct Chamelaucium cultivar named ‘EARLY NIR’ is disclosed, characterized by unique flower color, branch structure and early blooming. The new variety is a Chamelaucium, normally producing cut flower stems, or as a garden or container plant.

Description

Latin name of the genus and species: Chamelaucium uncinatum.

Variety denomination: ‘EARLY NIR’.

BACKGROUND OF THE INVENTION

The new Chamelaucium cultivar is a product of open pollination by the inventor, Nitzan Nir, in Kfar Hess, Israel. The new variety was discovered as a seedling growing in a field of various Chamelaucium uncinatum varieties during February of 2010, at a commercial nursery in Kfar Hess, Israel. The breeder has identified the seed parent as Chamelaucium ‘Della’, unpatented. The pollen parent is unknown.

Asexual reproduction of the new cultivar has been performed by vegetative cuttings. This was first performed at a commercial nursery in Kfar Hess, Israel in April of 2010 and has shown that the unique features of this cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The cultivar ‘EARLY NIR’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, 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 ‘EARLY NIR’. These characteristics in combination distinguish ‘EARLY NIR’ as a new and distinct Chamelaucium cultivar:

• • 1. Clear pink flower color, with a darker center.
  • 2. Unique branch structure.
  • 3. Early blooming
  • 4. High quantity of stems harvested per plant

PARENT COMPARISON

Plants of the new cultivar ‘EARLY NIR’ are similar to plants of the unpatented seed parent, Chamelaucium ‘Della’ , in most horticultural characteristics, however, plants of the new cultivar ‘EARLY NIR’ produce a different flower color and date of bloom than the seed parent. Flowers of the new variety are darker pink than flowers of ‘Della’. Additionally, flowers of the new variety have a dark Red-Purple hypanthium, whereas flowers of ‘Della’ have a pink hypanthium.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘EARLY NIR’ are comparable to the variety Chamelaucium ‘Nir’, unpatented. The two Chamelaucium varieties are similar in most horticultural characteristics; however, the new variety ‘EARLY NIR’ has a different date of bloom and flower color than the comparator. Flowers of ‘Nir’ are white to light pink, with a red-purple hypanthium. Flowers of ‘Early Nir’ are medium pink with a red-purple hypanthium.

Plants of the new cultivar ‘EARLY NIR’ can also be compared to the commercial variety Chamelaucium ‘M.B. Orchid’, unpatented. These varieties are similar in most horticultural characteristics; however ‘EARLY NIR’ has a different bloom date than the comparator.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph in FIG. 1 illustrates in full color a close up of typical flowers and foliage of ‘EARLY NIR’ at approximately 1 year of age. The photograph was taken using conventional techniques and although colors may appear different from actual colors due to light reflectance it is as accurate as possible by conventional photographic techniques.
