USPP36075P2 - Cistus plant named ‘MBNcistus2023’ - Google Patents

Abstract

A new and distinct Cistus purpureus cultivar named ‘MBNcistus2023’ is disclosed, characterized by very pale pink, nearly white flowers with a dark eye. The new cultivar is a Cistus, typically suited for ornamental garden use, or as a cut flower.

Description

Latin name of the genus and purpureus: Cistus purpureus.

Variety denomination: ‘MBNcistus2023’.

BACKGROUND OF THE INVENTION

The new variety originated as a chance discover by the inventor, Luen Miller. The variety was discovered as a naturally occurring branch mutation on a single plant of an unpatented, unnamed variety of Cistus purpureus. The new variety was discovered during April of 2020 at a commercial nursery in Royal Oaks, California in a commercial planting of the parent variety.

After selecting and isolating the new cultivar, asexual reproduction of the new cultivar ‘MBNcistus2023’ was first performed at a commercial nursery in Royal Oaks, California in April of 2020. Vegetative terminal cuttings were used for propagation. The inventor continued confidential, controlled evaluation and propagation of ‘MBNcistus2023’, to establish a stable clone. ‘MBNcistus2023’ has since produced two generations and has shown that the unique features of this cultivar are stable and reproduced true to type. Typical asexual reproduction of the new variety is by softwood vegetative cuttings.

SUMMARY OF THE INVENTION

The cultivar ‘MBNcistus2023’ 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 ‘MBNcistus2023.’ These characteristics in combination distinguish ‘MBNcistus2023’ as a new and distinct Cistus cultivar:

• 1. Very pale pink, nearly white flowers with a dark eye.

PARENTAL COMPARISON

Plants of the new cultivar ‘MBNcistus2023’ are similar to the parent in most horticultural characteristics. However, ‘MBNcistus2023’ differs in the following:

• 1. The new variety has very pale pink, nearly white flowers with a dark eye; the parent variety has medium pink flowers with a dark eye.

COMMERCIAL COMPARISON

Plants of the new cultivar ‘MBNCISTUS2023’ can be compared to the commercial unpatented, unnamed variety of Cistus ladanifer frequently found in the nursery trade. Plants of ‘MBNcistus2023’ are similar to plants of Cistus ladanifer in most horticultural characteristics, however, plants of ‘MBNcistus2023’ differ in the following:

• 1. The new variety has very pale pink, nearly white flowers with a dark eye; this comparator has white flowers with a dark eye.
• 2. Plants of the new variety are more mounding than the upright plants of Cistus ladanifer.
• 3. Foliage of the new variety is matte and scabrous; foliage of this comparator is glossy and glabrous.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph illustrates a comparison of the flower of the new variety (right side of the photo) with a flower of the parent variety (left side of the photos. Plants producing these flowers were approximately 18 months of age, grown in Royal Oaks, CA. 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.
