Aster plant named `Karmijn`
A new and distinct cultivar of aster plant designated `Karmijn` is short in height as flowering commences; produces dark green leaves without anthocyanin that are obovate in shape, and a flower head that is small to medium in size with many purple-violet ray florets that are narrowly elliptic in shape.
Latest De Nachtvlinder B.V. Patents:
The present invention comprises a new and distinct cultivar of aster plant hereinafter referred to by the cultivar name `Karmijn`.
The new cultivar was originated from a cross made by the inventor in a controlled breeding program in Ter Aar, The Netherlands. The female or seed parent was a selection from proprietary breeding stock designated the "Butterfly family" while the male or pollen parent was a selection from proprietary breeding stock designated the "P" family.
`Karmijn` was discovered and selected by the inventor as a flowering plant within the progeny of the stated cross in a controlled environment in Ter Aar, The Netherlands. Asexual reproduction of the new cultivar by cuttings, as performed by the inventor at Ter Aar, The Netherlands for the first time in April 1993, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for the new cultivar are firmly fixed and retained through successive generations of asexual reproduction.
`Karmijn` has not been observed under all possible environmental conditions. The phenotype may vary with variations in environment such as temperature, light intensity and day-length, without a change in the genotype of the plant. The following observations, measurements and values describe the new cultivar as grown in Bet Dagan, Israel, under conditions which closely approximate those generally used in commercial practice.
The following traits have been repeatedly observed and are determined to be basic characteristics of `Karmijn`, which in combination distinguish this aster as a new and distinct cultivar:
1. The plant height is short as flowering commences.
2. The leaves are obovate shaped, of medium length and dark green in color without anthocyanin coloration.
3. The first flower heads produced are spread along the axis.
4. The flower head is small to medium in size with many ray florets.
5. The ray florets are medium in length and narrowly elliptic in shape.
6. The involucre is campanulate in shape and medium in length.
7. The flower response is medium compared to other aster cultivars.
The new cultivar is most similar to `Milka` (U.S. plant patent application Ser. No. 08/664,519) and `Parade` (U.S. plant patent application Ser. No. 08/664,669), both of which are described in co-pending applications of the inventor. Each of these cultivars produces flowers with many ray florets and a similar type of flower head. The cultivars differ, however, with respect to flower color, speed of growth, plant height, leaf shape and leaf length.
The following Table provides several phenotypic characteristics that can be used to distinguish the aster varieties `Parade`, `Milka` and `Karmijn`.
