Vinca

Botany
Family: Lamiaceae (mints).
Scientific names:  Agastache astromontana (as listed by Kieft Seeds Holland; see A. pallidiflora below).

Taxonomic note: clarification of a scientific name for best-of-class is important for future trials and accurate reporting.  The epithet “astromontana” was not found in the The Germplasm Resources Information Network (GRIN); however, Monarda austromontana Epling is listed.  Further evaluation by the seed company indicates the probable species is Agastache pallidiflora ssp. neomexicana (Briq.) Lint & Epling [accepted name - The Integrated Taxonomic Information System (ITIS)].  Further confirmation by a taxonomist will be forthcoming.  Agastache: from agan, "very much," and stachys, "an ear of corn or wheat," having many spikes (ref. genus Agastache).

Agastache scrophulariifolia*** (Willd.) Kuntze.
Common names: *Bill Williams Mountain giant hyssop, New Mexican giant hyssop, **Bill William hyssop, Bill Williams Mountain giant hyssop or Bill Williams' Mountain giant; ***purple giant-hyssop.
Native habitat: *A. pallidiflora: North America in the Southwestern United States in Santa Cruz County, Arizona; Northern Mexico in the states of Chihuahua, Durango and Sonora (GRIN).  

Agastache scrophulariifolia: North America in the Canadian province of Ontario; Northeastern United States in the states of Connecticut, Indiana, Massachusetts, Michigan, New York, Ohio, Pennsylvania, Vermont; North-Central United States in the states of Illinois, Iowa, Kansas, Minnesota, Missouri, Nebraska and Wisconsin; Southeastern United States in the states of  Georgia, Kentucky, Maryland, North Carolina, South Carolina, Tennessee and Virginia (GRIN).

Pests
Common plant arthropods (insects/other)/other:   Reported arthropod symptoms in literature: 
Arthropod symptoms observed in this trial: This season, neither cultivar had a major problem.  ‘Garden Leader Blush’ had minor foliar feeding scars from the garden fleahopper.  Whitefly adults have been observed on 'Pink Pop' in the spring 2002 trial, but no symptoms affecting the quality of the plant were observed then.
Common plant diseases/other:   Reported disease symptoms in literature: Mildews and rusts have been reported.
Diseases symptoms observed in this trial: Crown rot was not diagnosed, but crown rot-like symptoms were present.  These symptoms occurred much earlier in the season for Pink Pop in spring 2002, allowing for only one evaluation.
Commercial control:  Greenhouse. Feld/shade house.
Arthropod information: Pests identified on crops.

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 for Agastache species in this special comparison.
Comments:  Best-of-class, spring 2002.  We compared two uncontested classes to provide useful information on crop performance between species.  Both 'Garden Leader Blush' (A. scrophulariaefolia) and 'Pink Pop' (A. astromontana) are uncontested best-of-class for their species/color classes.  ‘Pink Pop’ was a superior plant, statistically, with much higher ratings for foliage and flower throughout most of or all season.  ‘Pink Pop’ produced extremely uniform plants and flower coverage.  Flower color was not brilliant here; due smaller floret size, the color did not stand out greatly from the perfect foliage.  Most of the evaluations for both foliage/flower quality and pest symptoms had to be conducted in the unsprayed field, due to excess plant death in the sprayed field early in the test.  Pest problems on foliage and flowers were not important, but the symptoms of crown rot from soilborne pathogens were more serious in late June for this cultivar.
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.

Honors:
Comments: New for spring 2004.  Both 'Garden Leader Blush' and 'Pink Pop' are uncontested best-of-class for their species classes.  ‘Garden Leader Blush’ had lodged plants that lacked uniformity in the plot, though flower color was more pronounced from the larger, very pale pink florets.  It should be noted that very good plugs with healthy foliage and root systems were produced for both species.  ‘Garden Leader Blush’ plugs were less uniform for our trial, and the number of their germinated seedlings was less; but listed seed number/seed pack was reported equal for both cultivars, and no disease was observed in the plug flat.  Most of the evaluations for both foliage/flower quality and pest symptoms had to be conducted in the unsprayed field, due to excess plant death in the sprayed field early in the test.  Pest problems on foliage and flowers were not important, but the symptoms of crown rot from soilborne pathogens were serious in early June for this cultivar.
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.
