Abstract

Portulaca ‘Kakegawa CY2’ is a new variety of Portulaca oleracea. This plant has a vigorous, spreading plant growth which produces unique yellow color with purplish red streaks on the flowers.

Description

Genus and species: Portulaca oleracea.
Variety denomination: ‘Kakegawa CY2’.
BACKGROUND OF THE NEW PLANT
This invention relates to a new and distinct cultivar of Portulaca plant, hereinafter referred to by the name ‘Kakegawa CY2’. Portulaca ‘Kakegawa CY2’ 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 color with purplish red streaks. The flowers are single and measure approximately 4.5 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 CY2’ has been reproduced by stem cuttings in Salinas, Calif., and all of the characteristics thereof have been determined to be firmly fixed.
The new variety originated from a hybridization made in June, 1997 between the varieties ‘Duet Yellow’ (not patented) and ‘Duet Rose’ (not patented). F1 seed was sown from this cross in February, 1998 and three plants were selected for having striped petals. Ten plants were vegetatively propagated from each selection. In June, 1998 and again in September, 1998 the plants from each selection were vegetatively propagated and evaluated for stability. One of the original selections was selected as the most appealing and most stable. This selection possessed predominantly yellow petals with numerous streaks of purplish red, a red pistil with red filaments and yellow anthers. In April, 1999 the selected line was vegetatively propagated again and stability of habit, color and petal striping was confirmed.
BRIEF DESCRIPTION OF DRAWINGS
The accompanying drawings serve by color photographic means to illustrate the new plant variety, ‘Kakegawa CY2’. The colors are represented as true as possible using conventional photographic procedures.
FIG. 1 is a close-up view of a ‘Kakegawa CY2’ 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.
