Honors

Best-of-class (BC).  We select the best performer in each class, based on the "overall rating".  This rating may not be high, if the class does not perform well; also, the rating may not be significantly different from one or more members of the class. If two or more members of a class received the same overall rating, we used another rating to determine BC.  If only one cultivar was entered in a class, it automatically becomes uncontested BC.  See "Research Papers". Data has been taken to spring 2002; papers are being converted to PDF or in the process of review, and will be added to the trials web page soon.  Other "honors" received for these cultivars maybe added at a later date, time permitting.  Seed companies may forward these honors (awards) to Rick Kelly

Rating System

Foliage and flower ratings are combined to generate the "overall rating" listed below for each cultivar within its class.  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 rating, if it is a significant problem.  Refer to "Research Papers" for details.  Generally, 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.

Petunias planted April 1 and 2; plots photographed May 5, 2002.  See "full listings" for view of large pictures, later pictures (if any), and more information.

The Millifloras

"Until recently, garden centers offered two basic types of petunias, "grandiflora" petunias (large-flowered) and "multiflora" petunias (medium sized flowers, but more of them), both of which are still available in a wide array of solid colors and bi-colors. Now those categories are joined by petite "milliflora" or 'Fantasy' petunias and spreading or "groundcover" petunias.

Milliflora petunias culminate years of work by Mary Hunsberger who earned her phD here in vegetable breeding in the University of Minnesota's Department of Horticultural Science, then went on to become a flower breeder for Goldsmith Seeds in Gilroy, California.

As compact, miniature plants that produce abundant quantities of perfect, small flowers, milliflora petunias help fill a niche previously held by sweet allysum, lobelias and other small-statured annuals. Unlike traditional petunias, each plant grows only eight to ten inches tall, with flowers an inch to inch and a half across." (extracted from: Petunias; Old-Fashioned and More, by Deborah Brown, Extension Horticulturist, Yard & Garden Line News, Vol. 1, No. 6, July 15, 1999, Univrsity of Minisota Extension Service).
