Plant Ratings From 2014 Trials Now Available In Plant Trials Database

Plant Ratings From 2014 Trials Now Available In Plant Trials Database

Now that North American trial grounds have completed their 2014 trialing season, the National Plant Trials Database has more than 15,000 plant ratings for the horticulture industry’s use in planning for 2015. Each year since its inception in 2012, the number of varieties and ratings have increased, making the database an ever more useful tool for flower brokers, buyers and sellers.

Here are some of the trialing details by year:

  • 2012 – 1,655 varieties with more than 5,600 ratings from eight trial grounds
  • 2013 – 2,463 varieties with more than 9,400 ratings from 12 trial grounds
  • 2014 – 3,651 varieties with more than 15,500 ratings from 19 trial grounds

The initial idea for an online repository of trialing data came out of a collaboration between
All-America Selections and the University of Georgia. After identifying and establishing standardized trialing protocols and scoring, the system was built in 2012 and is currently supported by the following breeding companies:

  • American Takii
  • Danziger “Dan” Flower Farm
  • Dummen Group
  • Ernst Benary of America
  • Floranova Ltd.
  • PanAmerican Seed/Ball Horticultural
  • Proven Winners
  • Sakata Ornamentals
  • The Suntory Collection
  • Syngenta Flowers
