Abstract

Portulaca ‘Kakegawa CY1’ is a new variety of Portulaca oleracea. This plant has a vigorous, spreading plant growth which produces unique yellow and orange bi-colored flowers.

Description

Genus and species: Portulaca oleracea.
Variety denomination: ‘Kakegawa CY1’.
BACKGROUND OF THE NEW PLANT
This invention relates to a new and distinct cultivar of Portulaca plant, hereinafter referred to by the name ‘Kakegawa CY1’. Portulaca ‘Kakegawa CY1’ is a new variety of Portulaca oleracea. The plant has a vigorous spreading growth habit and can be used as a groundcover. It can also be used in a potted or hanging basket presentation. The invention's flowers are a unique yellow and orange bicolor. The flowers are single and measure approximately 3.5 centimeters in diameter when fully open. 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. ‘Kakegawa CY1’ has been reproduced by stem cuttings in Salinas, Calif., and all of the characteristics thereof have been determined to be firmly fixed.
In June, 1998 the breeder identified a sport from the variety ‘Summer Baby Orange’ (not patented) that possessed orange petals with yellow patches along the margin. The selection was made in the breeder's greenhouse in Kagoshima, Japan. The new variety was isolated by vegetative propagation. In April, 1999 and again in September, 1999 the new variety was vegetatively propagated and all progeny were found stable and uniform.
BRIEF DESCRIPTION OF DRAWINGS
The accompanying drawings serve by color photographic means to illustrate the new plant variety, ‘Kakegawa CY1’. The colors are represented as true as possible using conventional photographic procedures.
FIG. 1 is a close-up view of a ‘Kakegawa CY1’ flower illustrating its color and shape.
FIG. 2 is a view of several plants of the new cultivar growing in a 35.0 cm diameter pot.
DETAILED DESCRIPTION OF THE NEW VARIETY
The following description is based on observations and measurements from 14-16 week old plants grown in 15 cm pots at Salinas, Calif. Plants were propagated from vegetative cuttings and grown in a glass greenhouse. These plants were grown in plastic pots containing a peat moss-based medium. Soluble fertilizer containing 18% nitrogen, 8% phosphorus and 18% potassium were applied every fourth irrigation. The plants were typically watered twice per week. Pots were topdressed with a slow release fertilizer containing 18% nitrogen, 8% phosphorus and 18% potassium. The average air temperature was 24° C.
Color designations were made according to The Royal Horticultural Society Colour Chart published by The Royal Horticultural Society of London, England.
