USPP8714P - Plant of the cactaceae plant family named `Ashley` - Google Patents

Abstract

A new and distinct plant variety of the Cactaceae family is of the type known commercially as a `Spring Cactus` and has growth characteristics which are similar to those of the `Scarlet O'Hara` variety, but which are nevertheless modified by a combination of characteristics that include among others: flowers that have shorter and narrower tube laminating tepals, and different dominating hues of color in the tube laminating and tube forming tepals.

Description

BACKGROUND OF THE INVENTION

The invention relates to a new and distinct plant variety of the Cactaceae family which has been named Rhipsalidopsis gaertneri `Ashley` by the inventor.

Certain plant varieties of the Cactaceae family are well known in the foliage plant market and among these are those which are commonly referred to as the Spring or Easter cactus varieties because they tend to bloom in the Spring of the year.

The Spring cactus varieties on the market have blooms which vary in color from one variety to the next and are generally dominated by a red or closely related hue. One such cultivar in the marketplace at the time of application is `Scarlet O'Hara` having a red flower.

SUMMARY OF THE INVENTION

A general objective has been to develop a new plant variety which is distinguishable from the `Scarlet O'Hara` variety and which is capable of being marketed competitively therewith.

The objective has been fully realized in the development of the new plant variety hereinafter described in detail. The new plant variety was developed in a nursery located at Winter Garden, Fla., as an offspring secured by the self pollination of an unnamed research variety that is a descendent of the `Scarlet O'Hara` variety. The seeds taken from the fertilized seed pod were cultivated at the mentioned nursery location and after prolonged observation of the seedlings, the seedling of the new plant variety was selected and asexually reproduced by the invertor at the Winter Garden nursery by propagation of stem cuttings taken from the original seedling plant.

Through successive propagation, it has been ascertained that specimens of the new plant variety are distinguishable from specimens of the `Scarlet O'Hara` variety and other related varieties known to the inventor by a growth habit which is evident in plant specimens of the new plant variety that have been propagated and grown under nursery conditions utilized in the growing of topical plants in Winter Garden, Fla., as combining the following characteristics:

1. Flowers which, in comparison to the `Scarlet O'Hara` variety, have (a) a tube laminating tepal series with generally shorter length dimensions and generally smaller width dimensions, (b) a tube forming tepal series with generally shorter length dimensions and generally smaller width dimensions, (c) tube laminating and tube forming tepal series that are generally dominated by hues of orange, reddish orange, red and pink hues whereas the tepals of the `Scarlet O'Hara` variety are generally dominated by hues of red, purplish red, and pink.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawings serve by color photographic means to illustrate the new plant variety and wherein

one sheet shows a ten (10) month old specimen which was grown from the propagation of a single phylloclade in a conventional 31/2" plastic pot (trade designation) found in the marketplace.

A second sheet shows an enlargement of a fully open bloom taken from the specimen shown in the first mentioned sheet compared to a second bloom that has been taken from the same specimen and sectioned generally longitudinally through the perianth tube and ovary to expose the style and stamen arrangements.

DETAILED PLANT DESCRIPTION

The following is a detailed description of the new plant variety with colors and hues, unless otherwise clearly indicated by the text as, for example, through the absence of color notations, being named in accord with the ISCC-NBS Method of Designating colors (U.S. Dept. of Commerce, National Bureau of Standards, Circular 553), the named colors being interpreted from color specimens of the Munsell Book of Color. The description is further based on observations of well fertilized plants of about ten (10) months of age from initial propagation which were grown under 50%-75% shaded greenhouse nursery conditions in the Winter Garden, Fla. area and wherein temperatures range from 60°-85° F. during the winter months, from 75°-95° F. during the summer months, and are ambient during the intervening periods.

Claims (1)

We claim:

1. A new and distinct plant variety of the Cactaceae family as shown and described and which is mainly distinguished from its antecedents and known related varieties by growth characteristics that are similar to those of the `Scarlet O'Hara` variety but as modified by the combination of the following characteristics:

1. Flowers which, in comparison to the `Scarlet O'Hara` variety, have (a) a tube laminating tepal series with generally shorter length dimensions and generally smaller width dimensions, (b) a tube forming tepal series with generally smaller width dimensions, (c) tube laminating and tube forming tepal series that are generally dominated by hues of orange, reddish orange, red and pink, whereas the tepals of the `Scarlet O'Hara` variety are generally dominated by hues of red, purplish red, and pink.
