Claim: I claim:

1. A new and distinct cultivar of Astrantia plant named `Moulin Rouge` as herein illustrated and described.
Description: Botanicalclassification: Astrantia spp. hybrid.

Variety denomination: `Moulin Rouge`.


The present invention relates to a new and distinct cultivar of Astrantia or Masterwort, botanically of hybrid origin and known as Astrantia `Moulin Rouge` and will be referred to hereinafter by its cultivar name, `Moulin Rouge`.

The inventor discovered the new cultivar, `Moulin Rouge`, in a cultivated area of his nursery in the summer of 2000. The new cultivar was derived as a naturally occurring chance seedling. The parentage is unknown, however the cultivarsAstrantia major `Claret` (not patented), Astrantia major `Hadspen Blood` (not patented), and unnamed selections of hybrid Astrantia were growing in the vicinity and are possible parents.

`Moulin Rouge` was selected as unique for its dark red-purple inflorescences, its dark red-purple peduncles and pedicels and in particular for its long bloom season. It differs from its closest comparison cultivar, `Hadspen Blood` in that`Moulin Rouge` has larger, darker colored inflorescences and peduncles and blooms for an additional two months.

Asexual reproduction of the new cultivar was first accomplished by in vitro propagation under the direction of the inventor in Rijswijk, The Netherlands in 2002. The characteristics of this cultivar have been determined to be stable and arereproduced true to type in successive generations.


The following traits have been repeatedly observed and are determined to be the characteristics of `Moulin Rouge`. These characteristics in combination distinguish `Moulin Rouge` as a new and distinct cultivar of Astrantia. `Moulin Rouge` hasnot been observed under all possible environmental conditions and the phenotype may vary under different growing conditions without variance in genotype. 1. Large, dark purple red flowers with contrasting white stamens and deep purple bracts with verydark tips. 2. Dark purple red peduncles and pedicels held on sturdy stems. 3. Long blooming with three repeat flushes of bloom from early June to mid September in The Netherlands. 4. Upright plant habit and tolerant to wind and rain.


The accompanying colored photographs illustrate the overall appearance and distinct characteristics of one-year old plant of the new Astrantia.

The photograph on the first sheet provides a view of a typical flowering plant.

The photograph on the top of the second sheet is a close-up of the foliage and

The photograph on the bottom of the second sheet is a close-up of a flower.

The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new Astrantia.


The following is a detailed description of the new cultivar as grown under outdoors field conditions for one year in The Netherlands. They were grown under natural lighting with day temperatures ranging from to C. andnight temperatures of to C. The color determination is in accordance with the 2001 R.H.S. Colour Chart of The Royal Horticultural Society, London, England, except where general color terms of ordinary dictionary significance areused. The descriptions were taken in September of 2004.
