Description

Botanical classification: Cimicifuga ramosa.

Variety denomination: ‘Chocoholic’.

BACKGROUND OF THE INVENTION

The present invention relates to the new and distinct cultivar of Black Snakeroot, botanically known as Cimicifuga ‘Chocoholic’, and hereinafter referred to as the cultivar ‘Chocoholic’ or the “new plant”. The new plant was discovered by Marco van Noort in Warmond, The Netherlands in the summer of 2001 as a seedling of Cimicifuga ‘Brunette’ (not patented) from seed collected in fall 1999. The plant has been asexually propagated through division of the rhizome at the same nursery in Warmond, The Netherlands, and subsequent asexually propagated plants have been found to be identical to the original selection. ‘Chocoholic’ is in the Ranunculaceae family recognized as Cimicifuga ramose, but sometimes listed as Cimicifuga racemosa, Cimicifuga simplex, Actaea ramosa, Actaea racemosa, Actaea simplex and Actaea cimicifuga.

BRIEF SUMMARY OF THE PLANT

Cimicifuga ‘Chocoholic’ is unique from all other Black Snakeroot known to the inventor. Other forms have more green and less reddish-brown foliage and flowers with more white or lighter pink. The new plant has darker foliage than its female parent. The closest comparison variety is Cimicifuga ramosa ‘Hillside Black Beauty’ (U.S. Plant Pat. No. 9,988), which is different in that the new plant has dark greyed-purple foliage with more red tinting, and the flower buds of ‘Chocoholic’ are darker pink.

The following are traits of Cimicifuga ‘Chocoholic’ that in combination distinguish it from all other known Black Snakeroot known to the inventor:

    • 1. Upright habit with moderately glossy foliage of reddish brown to reddish-purple.
    • 2. Numerous strong, sweetly-fragrant flowers with dark greyed-red tepals and light creamy white tepals.
    • 3. Flower buds with dark greyed-red sepals.

BRIEF DESCRIPTION OF ME DRAWINGS

The photographs of the new plant demonstrate the unique traits of the new plant and the overall appearance. The colors are as accurate as reasonably possible with color reproductions. Variation in ambient light spectrum, source and direction may cause the appearance of minor variation in color.

 DETAILED BOTANICAL DESCRIPTION

The following descriptions and color references are based on the 2007 edition of The Royal Horticultural Society Colour Chart except where common dictionary terms are used. Cimicifuga ‘Chocoholic’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture and plant maturity levels, but without any change in the genotype. The following observations and size descriptions are based on two-year old field grown plants in Warmond, the Netherlands with average day temperatures ranging between +10° C. and 25° C. and night temperatures between +3° C. to 14° C. Plants were not provided any additional light and no growth retardants were used.
