Abstract

A new cultivar of Zantedeschia plant named ‘Royal Pumpkin’, that is characterized by its flowers that are a blend of orange, red and yellow in color, its high flower yield, its flowers with a long vase life, and its high resistance to Erwinia caratovora.

Description

Botanical classification: Zantedeschia Spreng.

Cultivar designation: ‘Royal Pumpkin’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Zantedeschia Spreng. and is hereinafter referred to by the cultivar name ‘Royal Pumpkin’. ‘Royal Pumpkin’ represents a new herbaceous perennial grown for use as a potted plant and cut flower.

The new cultivar was derived from a controlled breeding program by the Inventor in Maarssen, The Netherlands. The objective of the breeding program was to develop new cultivars of Zantedeschia with high bulb multiplication rates and flowers with high yields, long vase lives, and unique colors. The Inventor made a cross in May of 2006 between the unpatented cultivar ‘La Serena’ as the female parent and an unnamed and unpatented proprietary plant in the Inventor's breeding program, seedling no. 06213, as the male parent. The Inventor selected ‘Royal Pumpkin’ in August of 2008 as a single unique plant amongst the seedlings that resulted from the above cross.

Asexual propagation of the new cultivar was first accomplished under the direction of the Inventor by tuber division in 2009 in Breezand, The Netherlands. Asexual propagation by tuber division and tissue culture has determined that the characteristics of the new cultivar are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent the characteristics of the new cultivar. These attributes in combination distinguish ‘Royal Pumpkin’ as a new and unique cultivar of Zantedeschia.

- 1. ‘Royal Pumpkin’ exhibits flowers that are a blend of orange, red, and yellow in color.
- 2. ‘Royal Pumpkin’ exhibits flowers with a long vase life.
- 3. ‘Royal Pumpkin’ exhibits high flower yield.
- 4. ‘Royal Pumpkin’ has shown a high tolerance to root disease caused by Erwinia caratovora.

The female parent of ‘Royal Pumpkin’, ‘La Serena’, differs from ‘Royal Pumpkin’ in having flowers that are more orange-yellow in color and less uniform in color, leaves that are longer, and in having a more vigorous growth habit. The male parent of ‘Royal Pumpkin’, seedling no. 06213, differs from ‘Royal Pumpkin’ in having smaller flowers that are deeper orange in color, a more compact plant habit, and smaller leaves. ‘Royal Pumpkin’ can be most closely compared to the cultivars ‘Orania’ (2015/0296691), and ‘San Remo’ (not patented). Orania’ is similar to ‘Royal Pumpkin’ in having flowers in the same color range. ‘Orania’ differs from ‘Royal Pumpkin’ in having flowers that are less rounded in shape and more red-orange in color, leaves that are less rounded, and a plant habit that is less upright. ‘San Remo’ is similar to ‘Royal Pumpkin’ in having flowers in the same color range. ‘San Remo’ differs from ‘Royal Pumpkin’ in having smaller leaves that are more pointed, flowers that are less rounded in shape and more salmon orange in color, and in having a plant habit that is more upright.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearance and distinct characteristics of the new Zantedeschia. The photographs was taken of a plant about 12 weeks in age as grown in a greenhouse in a 6-inch in Honselersdijk, The Netherlands.

The photograph in FIG. 1 provides a side view of ‘Royal Pumpkin’ in bloom as grown under high light levels.

The photograph in FIG. 2 provides a side view of ‘Royal Pumpkin’ in bloom as grown under low light levels

The colors in the photographs may differ slightly from the color values cited in the detailed botanical description, which accurately describe the colors of the new Zantedeschia.

DETAILED BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed description of 12 week-old plants as grown in a greenhouse in 6-inch containers in Honselersdijk, The Netherlands. The phenotype of the new cultivar may vary with variations in environmental, climatic, and cultural conditions, as it has not been tested under all possible environmental conditions. The color determination is in accordance with The 2007 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance are used.
