ABSTRACT:
BACKGROUND OF THE NEW PLANT
This invention relates to a new and distinct cultivar of Portulaca plant, hereinafter referred to by the name ‘Summer Joy Deep Rose’. Portulaca ‘Summer Joy Deep Rose’ is a new variety of
Portulaca oleracea
. The plant has a vigorous spreading growth habit and can be used as a ground cover. It can also be used in a potted or hanging basket presentation. The invention's flowers are dark pink (RHS 74A) with a red (RHS 46A) center. The flowers are single and measure 5.4 to 5.8 centimeters in diameter when fully open. There are five distinct petals with an indent at the tip of each petal. Portulaca flowers will typically close under low light and low temperature conditions such as late in the day and at night. ‘Summer Joy Deep Rose’ Portulaca flowers will stay open later into the evening than most other cultivated varieties. The plant performs well in hot and dry climates. The plant is very resistant to rain, heat and drought.
ORIGIN AND ASEXUAL REPRODUCTION
The new cultivar is propagated asexually from vegetative cuttings. The asexual reproduction establishes that the plant does in fact maintain the characteristics described in successive generations. ‘Summer Joy Deep Rose’ has been reproduced by stem cuttings in Salinas, Calif., and all of the characteristics thereof have been determined to be firmly fixed.
‘Summer Joy Deep Rose’ originated from a hybridization made by the inventor Hiromi Matsukizono in Japan. The female parent is a commercial variety known as ‘Yubi® Rose’, an unpatented variety of Portulaca and the male parent was a commercial variety known as ‘Yubi® Apricot’. The initial cross-pollination of the parents, resulting in F
1
generation seed, was made in June, 1992. In February, 1993, the F
1
seed was sown. From these plants, five plants were selected for appealing flower color. In June through September of 1993 the five selected plant lines were vegetatively propagated and tested for easy reproducibility and stability of traits. One of these five plant lines was hence selected for dark pink flower color, large flower size and easy propagation. In February, 1997, cuttings of this plant line were sent to California. During the spring and summer of 1997 and 1998, plants were grown under the direction and supervision of the inventor for evaluation of the stability of the line's desired traits. Plants were evaluated in greenhouse pots at the research station at Salinas, Calif., and at the breeding station in Kakegawa, Japan. The invention, ‘Summer Joy Deep Rose’ Portulaca, was determined by the inventor to have its characteristics, as herein described, firmly fixed.
