Abstract: A chrysanthemum plant named `Twino Bronze` characterized by small-sized blooms with yellow-orange ray florets with bronze-orange centers, prolific branching, a natural season flowering date of October 10, a blooming period of 4 to 5 weeks, a rounded plant habit and a spreading growth habit, is disclosed.
Claim: I claim:

1. A new and distinct variety of chrysanthemum plant as described and illustrated.
Description: Genus: Chrysanthemum morifolium.

Variety denomination: `Twino Bronze`.

BACKGROUND OF THE INVENTION

`Twino Bronze` is a product of a breeding and selection program for outdoor pot mums (garden mums) which had the objective of creating new chrysanthemum cultivars with a decorative type inflorescence, a natural season flowering date aroundOctober 10 and a blooming period of 4 to 5 weeks. The new plant of the present invention comprises a new and distinct cultivar of chrysanthemum plant.

`Twino Bronze` is a seedling resulting from the open pollination conducted in September 2005 among groups of un-named and unpatented chrysanthemum cultivars maintained under the control of the inventor for breeding purposes. The new and distinctcultivar was discovered and selected as one flowering plant by Rob Noodelijk on a cultivated field in Woubrugge, The Netherlands in September 2006. `Twino Bronze` was first asexually reproduced by cuttings in greenhouses at Woubrugge, The Netherlands inJanuary 2007 and has been asexually reproduced over an approximately two-year period. The new cultivar has been found to retain its distinctive characteristics through successive asexual propagations.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of the new cultivar when grown under normal horticultural practices in Woubrugge, The Netherlands. 1. Small yellow-orange inflorescences with orange-bronze centers; 2. Very prolific branching; and 3. A rounded plant habit.

DESCRIPTION OF THE PHOTOGRAPHS

The present invention of a new and distinct variety of chrysanthemum is shown in the accompanying photographs, the colors being as nearly true as possible with color photographs of this type. The photographs are of a plant that has been in bloomfor approximately 3 weeks.

FIG. 1 shows a plant of the cultivar in full bloom.

FIG. 2 shows a close-up of the buds, florets, leaves and individual inflorescences.

DESCRIPTION OF THE INVENTION

This new variety of chrysanthemum is of the botanical classification Chrysanthemum morifolium. The observations and measurements were gathered from plants grown outdoors in Woubrugge, The Netherlands under natural day length and temperatures andplanted in week 22 in 2006 and 2007. The average natural blooming date of this crop was October 10. The average height of the plants was 37 cm. No growth retardants were used. No tests were done on disease or insect resistance or susceptibility. Notests were done on cold or drought tolerance. This new variety produces small-sized blooms with yellow-orange ray florets and bronze-orange centers and a blooming period of 4 to 5 weeks.

The following is a description of the plant and characteristics that distinguish `Twino Bronze` as a new and distinct variety. The color designations are taken from the plant itself. Accordingly, any discrepancies between the color designationsand the colors depicted in the photographs are due to photographic tolerances. The color chart used in this description is The Royal Horticultural Society Colour Chart, edition 1995.

COMPARISON WITH COMMERCIAL CULTIVARS

`Twino Bronze` differs from the commercial variety `Katelli` (U.S. Plant Pat. No. 16,674) in that `Twino Bronze` blooms later (October 10) than `Katelli` (September 13 20). Additionally, `Twino Bronze` has less ray florets (170 to 200) andleaves per lateral branch (7 to 12) than `Katelli` (has 240 to 250 ray florets and 25 leaves per branch).
