| Abstract: |
A new and distinct cultivar of Asteriscus maritimus plant named `Asmago` characterized by its earliness, flat mounding growth habit, large golden yellow flowers, silvery colored leaves and good branching. |
| Claim: |
What is claimed is:
1. A new and distinct variety of Asteriscus maritimus plant, substantially as herein illustrated and described. |
| Description: |
Latin name of the genus and species of the plant claimed: Asteriscus maritimus.
Varietal denomination: `Asmago`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct cultivar of Asteriscus plant botanically known as Asteriscus maritimus and referred to by the cultivar name `Asmago`.
The new cultivar is a product of a planned breeding program conducted by the inventor in Enkhuizen, Netherlands. The new cultivar is an early flowering plant with a flat growth habit, good branching, large flowers, and silvery foliage withflowers all summer.
The new Asteriscus originated from a cross-pollination made by the inventor in September 2000 of a proprietary selection of Asteriscus maritimus identified as code number `A231-1` not patented, as the female, or seed parent, with a proprietaryselection of Asteriscus maritimus identified as code number `A323-1,` not patented, as the male, or pollen parent. `A231-1` is later flowering, has a more upright plant habit, and is not branching when compared to the new Asteriscus. `A323-1` is notfloriferous and has smaller flowers with shorter petals when compared to the new Asteriscus. The new Asteriscus was selected as a single plant from the resulting progeny of the cross-pollination in a controlled environment in Enkhuizen, Netherlands inAugust 2001.
Asexual reproduction of the new cultivar by terminal vegetative cuttings since August 2001, in Enkhuizen, Netherlands has shown that the unique features of this new Asteriscus are stable and reproduced true to type in successive generations.
DESCRIPTION OF THE DRAWING
This new Asteriscus plant is illustrated by the accompanying photographic drawing which shows blooms, buds and foliage of the plant in full color, the color shown being as true as can be reasonably obtained by conventional photographicprocedures.
DESCRIPTION OF THE NEW CULTIVAR
The following detailed descriptions set forth the distinctive characteristics of this new Asteriscus plant. The data which defines these characteristics were collected from asexual reproductions carried out in Enkhuizen, The Netherlands. Theplant history was taken on 20 weeks old plants, grown in the field in Enkhuizen, The Netherlands with day temperatures ranging from 16 to 30 degree C., and night temperatures ranging from 10 to 16 degrees Celsius.
Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London where general terms of ordinary dictionary significance are used.
