Cactaceae plant

Abstract

A new and distinct hybrid plant variety of the Cactaceae family is related to the Zygocactus truncatus `Kris Kringle` and Zygocactus truncatus `Lavender Doll` varieties and is principally distinguished by a growth habit which combines characteristics that include a natural tendency to branch without inducement by pruning during the growth period, a fast growth rate with resistances to nutrient deficiencies and fungus type diseases that are comparable to those of the `Kris Kringle` and `Lavender Doll` varieties, a resistance to flower bud abscission that is comparable to those of the `Kris Kringle` and `Lavender Doll` varieties and a flower that blooms earlier than that of the `Lavender Doll` variety and has a bloom life of from about 6 to about 9 days, a pistil with a style that is translucent white at its proximal end and in color at its distal end is dominated by purplish red and/or reddish purple hues and with a stigma which is translucent white, and tepals which have marginal blade areas that in color are dominated by purplish red and/or reddish purple hues and which include a sepaloid series of free tepals with inner whorl members having basal areas that in color are dominated by a purplish pink hue, a perianth tube forming series of basally united tepals that form a translucent white vestigal carina at the throat of the tube, and a series of tube laminating tepals which usually number from 5 to 7 in the bloom.

Description

The invention relates to a new and distinct plant variety of the Cactaceae family and which has been named the Zygocactus truncatus `Christmas Charm` by the inventor.

Certain plant varieties of the Cactaceae family are well known in the foliage plant market and among those are those of the truncatus species of the Zygocactus genus. These varieties tend to bloom in the months of November and December in the Northern Hemisphere and hence they appear in the retail market area primarily during the Thanksgiving and Christmas seasons and wherein they are commonly referred to as a "Christmas Cactus".

The Zygocactus truncatus `Kris Kringle` forms the subject matter of U.S. Plant Pat. No. 3,688 and has a heritage that includes the variety known commercially as `Christmas Cheer` and the variety known as Zygocactus truncatus `Parma`. It has a "reddish" colored bloom and a bloom life which provides a suitable shelf life at the retail level of sales. The variety also has a fast growth rate with substantial resistances to nutrient deficiencies and to fungus type diseases. The `Kris Kringle` variety also has a substantial resistance to flower bud abscission and is endowed with a natural tendency to branch without inducement by pruning during the growth period before blooming. The growth rate, resistances, and branching tendencies are much sought after by growers of the so-called "Christmas Cactus" varieties.

The Zygocactus truncatus `Lavender Doll` is yet another recent development among the so-called "Christmas Cactus" varieties and it forms the subject matter of U.S. Plant Pat. No. 3,690. The `Lavender Doll` variety has a heritage that also includes the `Christmas Cheer` variety and it has a growth habit which includes the mentioned resistance characteristics attributable to the `Kris Kringle` variety but the natural tendency to branch without inducement by pruning during the growth period preceding blooming is not as profuse as that resident in the `Kris Kringle` variety. The `Lavender Doll` has what may be called a "purplish" colored bloom and like the `Kris Kringle` variety, has rapidly acquired a broad market acceptance that has created a demand among nurserymen for different colored varieties of the so-called "Christmas Cactus" types and which have the growth rate and natural resistances to nutrient deficiencies, fungus type diseases and flower bud abscission that are exhibited by the `Kris Kringle` and `Lavender Doll` varieties.

A general objective of the invention has been to develop a variety of the truncatus species which has the growth rate and previously mentioned resistance characteristics that are associated with the `Kris Kringle` and `Lavender Doll` varieties but which have color characteristics that are distinguishable from those of such varieties and a bloom that matures at an earlier date than that of the `Lavender Doll` variety.

The objectives of the invention have been fully realized by the development of the new plant variety described hereinafter in detail. The new plant variety was developed in a nursery located at Winter Garden, Fla., as a hybrid secured by cross-pollinating the flower of a plant specimen of a variety developed by the inventor from a vegetative mutation that appeared on a specimen of the `Lavender Doll` variety with pollen from a plant specimen of the `Kris Kringle` variety. The maternal variety is a research variety which has not appeared in the marketplace and it is distinguishable from the `Lavender Doll` variety primarily by a growth habit which produces slightly larger phylloclades and specimens with somewhat poorer natural branching tendencies than those exhibited by the `Lavender Doll` variety. The seeds taken from the fertilized seed pod of the maternal variety were cultivated at the mentioned nursery location and after prolonged observation of the seedlings, the hybridized plant of the new plant variety was selected and asexually reproduced by the inventor at the Winter Garden nursery through the propagation of stem cuttings taken from the original hybrid plant.

Through successive propagations, it has been ascertained that specimens of the new plant variety generally resemble the parent varieties but are distinguishable from the parent varieties and from other related varieties known to the inventor by a growth habit which is evident in specimens propagated and grown under nursery conditions utilized in the growing of tropical plants at Winter Garden, Fla., as combining the following principal characteristics:

1. A natural tendency to branch without inducement by pruning during the growth period before blooming and which is comparable to that of the `Kris Kringle` variety.

2. A fast growth rate with resistances to nutrient deficiencies and fungus type diseases that are comparable to those of the `Kris Kringle` and `Lavender Doll` varieties.

3. A resistance to flower bud abscission that is comparable to those of the `Kris Kringle` and `Lavender Doll` varieties.

4. A flower which blooms from about one to three weeks earlier than that of the `Lavender Doll` variety and has a bloom life of from about 6 to about 9 days and which has a pistil with a style that is translucent white at its proximal end and in color is dominated at its distal end by purplish red and/or reddish purple hues and with a stigma that is translucent white, and which also has tepals that have marginal blade areas which in color are dominated by purplish red and/or reddish purple hues and that include a sepaloid series of free tepals with inner whorl members having basal areas which in color are dominated by purplish pink hue, a perianth tube forming series of basally united tepals which form a translucent white vestigal carina at the throat of the tube, and a series of tube laminating tepals that usually number from 5 to 7 in the bloom.

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

One sheet is a color photograph of a blooming 6 month old plant specimen of the new plant variety, a second sheet shows color photographs of other blooming specimens and a third sheet embodies color photographs which further illustrate the blooms and certain parts thereof.

The following is a detailed description of the new plant variety with colors and hues, unless otherwise clearly indicated by the text through the absence of color notations, being named in accord with the ISCC-NBS method of designating colors (U.S. Department of Commerce, National Bureau of Standards, Circular 553, issued Nov. 1, 1955), the named colors being interpreted from color notations derived by comparison with the color specimens in the current "Neighboring Hues Edition" of the Munsell Book of Color, published by the Munsell Color Company, Inc., of Baltimore, Md. The following description is further based on observations of well fertilized plants of less than one year of age from initial propagation and which were grown under 50-75% shaded glasshouse nursery conditions in the Winter Garden, Fla., area and wherein temperatures range from 60.degree. to 85.degree. F. during the winter months, from 75.degree. to 95.degree. F. during the summer months and are ambient during intervening periods.
