| Abstract: |
A new and distinct cultivar of aster plant named `Peter's White`, characterized by its white ray floret color; short flowering height; elliptic-linear shaped leaved which are medium to long in length, dark green in color and sometimes with a slight anthocyanin coloration; first flower heads spread along the axis; medium to large flower heads with many ray florets; medium to long ray florets that are narrowly elliptic in shape; long, cylindrical shaped involucre; and late flowering. |
| Claim: |
I claim:
1. A new and distinct cultivar of aster plant named `Peter's White`, as illustrated and described. |
| Description: |
The present inventioncomprises a new and distinct cultivar of Aster plant hereinafter referred to by the cultivar name `Peter's White`.
BACKGROUND OF THE INVENTION
The new cultivar was originated from a cross made in a controlled breeding program in Ter Aar, Holland. The female or seed parent was a selection from proprietary breeding stock designated the "Butterfly family" while the male or pollen parentwas a selection from proprietary breeding stock designated the "P" family. `Peter's White` 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, Holland. Firstasexual reproduction of the new cultivar by cuttings was in December 1994. Subsequent asexual reproduction by cuttings of the new cultivar as performed by applicant at Ter Aar, Holland, has demonstrated that the combination of characteristics as hereindisclosed are firmly fixed and retained through successive generations.
`Peter's White` 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 only change in the genotype of the plant. Thefollowing observations, measurements and values describe the new cultivar as grown in Ter Aar, Holland under conditions which closely approximate those generally used in commercial practice.
The new cultivar is most similar to `Milka` , U.S. Plant Patent application Ser. No. 8/664,519) `Karmijn` U.S. Plant Patent application Ser. No. 8/664,520, and `Parade` U.S. Plant Patent application Ser. No. 8/664,669, each of the cultivarshas a similar number of ray florets and type of flower head. The following Table provides several phenotypic characteristics that can be used to distinguish the aster varities `Parade`, `Milka`, `Karmijn`, and `Peter's White`.

BRIEF SUMMARY OF THE INVENTION
The following traits have been repeatedly observed and are determined to be basic characteristics of `Peter's White` which in combination distinguish this aster as a new and distinct cultivar:
1) As flowering commences `Peter's White` is very short to short.
2) Leaves are elliptic-linear shaped, medium to long in length, dark green in color without anthocyanin coloration.
3) The first flower heads produced are spread along the axis.
4) The flower head is medium to large in size with many ray florets.
5) The ray florets are medium to long in size and narrowly elliptic in shape.
6) The involucre is cylindrical in shape and very long.
7) Flowering commences very late compared to other asters.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic drawing shows a typical specimen plant of the new cultivar. The colors appearing in the photograph are as true as possible with color illustrations of this type.

II. Plant
A. General appearance: The plants are very short to short in height as flowering commences. The leaves produced by `Peter's White` are elliptic-linear in shape, medium to long in length and are dark green in color. The first flower headsproduced are spread along the axis. The flower head is medium to large in size with many ray florets. The ray florets are medium to long in size and narrowly elliptic in shape. The involucre is cylindrical in shape and very long.
