All-America Selections Looking for Entries for 2019 Plant Trials

herbaceous perennialsIn 2015, All-America Selections (AAS), in conjunction with the Perennial Plant Association (PPA), successfully launched a new herbaceous perennial trial with five entries and corresponding comparisons currently planted and undergoing their third summer of evaluations. The first of those winners will be announced in July 2019. Subsequent trial years have resulted in additional perennial entries that the AAS judges are evaluating.

The organizations are now accepting entries for the 2019-2022 (three-winter) trial. The entry submission deadline for herbaceous perennials is Sept. 1, 2018 to coincide with breeders’ timeline of summer evaluations and introduction decisions. Click here to learn more about how to submit an entry.


Entries have to be new and never-before-sold, but after submission to the Herbaceous Perennial Trial, they may be introduced commercially. After the trial is completed, if the entry scores high enough to become an AAS Winner, after criteria is met and the announcement is made by AAS, the breeder may then market that variety as an AAS Winner.

Entries accepted will be herbaceous perennials propagated from seed, cutting, tissue culture, or bare root. A seed entry can be trialed against a vegetative or tissue culture comparison and vice-versa. Entries will be trialed next to comparisons to continue the AAS legacy.

AAS is also now accepting entries for the other three trials:
• Ornamentals propagated from vegetative cuttings
• Ornamentals propagated from seed
• Edibles/vegetables from seed

The deadline for these entries is Nov. 1, 2018, and they are trialed over one growing season. Breeders who wish to have their herbaceous perennials tested for first-season performance can continue to use the one-season trial. Complete information is available on the AAS website.

Entries and comparisons are sent to all trialing sites in early 2019.
