Latin name of genus and species of plant claimed: Dampiera hybrida.

Variety denomination: ‘Altmp2336’.

STATEMENT REGARDING PRIOR DISCLOSURES BY THE INVENTOR

The first offer for sale of the new variety was Jul. 12, 2024, in the United States of America, at the New Varieties Showcase at the Cultivate Trade Show in Columbus, Ohio, followed by the publication of the 2025 Star Roses and Plants Woody Ornamentals & Edibles Catalog released Oct. 7, 2024. The first offer for sale of the new variety was by an inventor or another who obtained the new variety directly or indirectly from an inventor. No plants of the new variety have been sold in this country or anywhere in the world, nor has any disclosure of the new plant been made, more than one year prior the effective filing date of this application, and such sale or disclosure within one year was either derived directly or indirectly from the inventor.

BACKGROUND OF THE INVENTION

The new variety of Dampiera hybrida plant originated in a controlled breeding program in Perth, Western Australia in March 1999. The objective of the breeding program was to develop new ornamental plant varieties. The new cultivar is the result of cross pollination. The female (seed) parent (unnamed) of the new cultivar is a proprietary breeding selection (not patented). The male (pollen) parent (unnamed) of the new cultivar is a different proprietary breeding selection (not patented).

The parentage of the new variety can be summarized as follows: proprietary breeding selection x different proprietary breeding selection

The seeds resulting from the above cross pollination were sown and small plants were obtained which were physically and biologically different from each other. The new cultivar was selected as a single flowering plant during September 1999, in a controlled environment in Perth, Western Australia.

The new variety has been found to undergo asexual propagation by terminal stem cuttings and in vitro propagules in Perth, Western Australia. Asexual propagation by terminal stem cuttings and in vitro propagules in Perth, Western Australia has shown that the characteristics of the new variety are stable and are strictly transmissible by such asexual propagation from one generation to another. Accordingly, the new variety undergoes asexual propagation in a true-to-type manner.

SUMMARY OF THE INVENTION

It was found that the new variety of Dampiera plant of the present invention possesses the following combination of characteristics:

• (a) forms purple-colored flowers, • (b) displays silver grey-colored foliage, and • (c) exhibits a low growing, moderately vigorous, spreading growth habit.

The new variety well meets the needs of the horticultural industry. It can be grown to advantage as ornamentation in parks, gardens, public areas, and in residential settings. Accordingly, the plant is particularly well suited for growing in the landscape.

The new variety of the present invention can readily be distinguished from its ancestors. More specifically, the new variety displays darker purple-colored flowers and extended flowering compared to the lilac purple-colored flowers of the female proprietary breeding selection parent (i.e., the seed parent). Additionally, the new variety forms flowers that are lighter purple in color and exhibits a more spreading habit compared to the different proprietary breeding selection (i.e., the pollen parent), which forms deep purple-colored flowers and exhibits a bushy growth habit. Moreover, the new variety can be readily distinguished from non-parental related similar varieties. For example, the new variety exhibits a more spreading habit, forms lighter purple-colored flowers and displays extended flowering compared to plants of the straight species Dampiera incana.

The new variety has been named ‘Altmp2336’.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographs show as nearly true as it is reasonably possible to make the same, in a color illustration of this character, typical specimens of the plant and plant parts of the new variety. Colors in the photographs may differ slightly from the color values cited in the detailed description, which accurately describes the colors of the ‘Altmp2336’ variety. The photographed plants were approximately one year old and grown in three-gallon containers in Cochranville, Pennsylvania. The photographs were taken in November 2020.

DETAILED BOTANICAL DESCRIPTION

The chart used in the identification of the colors is that of The Royal Horticultural Society (R.H.S. Colour Chart), 2015 edition, London, England. The terminology which precedes reference to the chart has been added to indicate the corresponding color in more common terms and The R.H.S. Colour Chart designation used herein represents the closest color observed on the majority of the specified botanical feature. The color values were determined in November 2023, under natural light conditions in Cochranville, Pennsylvania. The description is based on the observation of plants produced from cuttings from stock plants and grown in three-gallon containers for approximately one year in an outdoor nursery in Cochranville, Pennsylvania. Plants were pinched once after transplant.
