Botany

Family:	Amaranthaceae (amaranthes or pigweed).
Scientific names:	Celosia argentea L. var. argentea; Celosia argentea L. var. cristata (L.) Kuntze; and Celosia argentea L. var. plumosa Voss [The Germplasm Resources Information Network (GRIN)]; also referred to in literature as Celosia argentea (Cristata Group), *Celosia argentea (Plumosa Group) and Celosia argentea* (Spicata Group).
Common names:	*cockscomb, logos-spinach, **plumeflower (GRIN); also referred to in literature as spiked celosia and plumed celosia or *plume cockscomb.
Native habitat:	Celosia argentea: listed as a pantropical weed; native habitat uncertain, possibly native to India (GRIN).

Pests
Common plant arthropods (insects/other)/other:	Reported arthropod symptoms in literature: Spider mites, red wax scale (Featured Creatures, U. of Florida); root-knot nematodes (USDA - Agricultural Research Service).
	Arthropod symptoms observed in this trial: We have seen large numbers of the false chinch bug (Nysius raphanus), but damage was not determined. Beet armyworm damage was observed on all cultivars, but was only serious on one plant early May. Parasites were observed later in the season and no more armyworms were observed feeding on this crop. Pictures of the parasites may be seen by clicking on the gator:. Some leaf mines (probably the American serpentine leafminer) were seen, but were not a serious problem.
Common plant diseases/other:	Reported disease symptoms in literature: Alternaria sp., leaf spot; Cercospora celosiae, leaf spot; Fusarium sp., stem rot. (Index of Plant Diseases in Florida, 1984 revision.).
	Diseases symptoms observed in this trial: No foliar symptoms were observed, other than a blight-like necrosis, possibly associated with a soilborne pathogen problem. 87 % of the plants died showing crown rot symptoms for ‘Ice Cream Orange’; while ‘Orange Glow lost 13 % and ‘Spiky Pink lost 7 %. ‘Ice Cream Cherry Red’, Carmine Glow and Kosmo Purple Red did not have plant deaths in the unsprayed field.

Honors:

Best-of-class (BC). We select the best performer in each class, based on the "overall performance rating". This rating may not be high, if the class does not perform well (indicating a possible need for improvement in the class). The rating may be significantly different from one or more members of the class. If two or more members of a class received the same highest overall performance rating, we used another rating (such as overall foliage/flower rating or flower average rating) to determine BC. If only one cultivar was entered in a class, it automatically becomes uncontested BC. BC is evaluated in future trials against the performance of new entries in the same class. Refer to a report in "Articles, Papers & Reports" for detailed information. In addition to BC, other "honors" received for these cultivars may be added to BC at a later date, time permitting. Seed companies may forward these honors (awards) to Rick Kelly.

Rating System:

The rating is a 1 to 7 scale: 7- all foliage and flowers free from defects; 4- average foliage and flower condition, minimal plant defects or pest damage to tissue, but still acceptable; 1- foliage and/or flowers with severe defects and/or severely infested with pests and damage unacceptable, making plant undesirable. Plant death due to soilborne pests may be factored into the overall performance rating, if it is a significant problem. Refer to a report in "Articles, Papers & Reports" for details. If listed, ratings with an "a" are the best in a class. If cultivars share the same letters, those ratings are considered to be similar to each other. If there are no letters, there is only one cultivar in a class or all the members of a class have similar ratings.

Honors: Best-of-class, uncontested.

Comments: New in spring 2004. The color was very striking, but overall performance was poor. Flower displays were variable but generally good in early May; foliage and flower ratings declined steadily as the season progressed. Eighty five percent of the plants died showing crown rot symptoms for ‘Ice Cream Orange’, while ‘Ice Cream Cherry Red’ did not have plant deaths.

Details of performance for this cultivar will be posted on the web in "Articles, Papers & Reports" at the completion of this trial. These details will include ratings over the entire season and pest problems.

ROK

1. The number of weeks from seed sowing to the date the plant was photographed. Photographs were taken in a field sprayed on demand as needed, after scouting for pests, and a field that is not sprayed at all.

2. Measured in centimeters and inches [cm (inches)].

3. Average number of days from sowing to unfurling of the first flower in the plots. Flowering for alyssum was completed in the flat prior to planting in the field. Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.

4. The average of the combined foliage and flower data in the sprayed field as an expression of cultivar quality. Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.

5. The average of the combined foliage and flower data in the unsprayed field as an expression of arthropod and disease symptoms. Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different.

6. The average of the combined overall foliage/flower rating and overall pest rating. If plant death from a soilborne pathogen resulted, this was factored into the rating. Values with an "a" are considered significantly greater than those with a "b", "c", etc., and those without a letter are not considered to be significantly different. See Articles, Papers & Reports for further explanation in the reports.
