Plant Introductions, Inc.

Developers of Superior Garden Plants

that Perform as Promised


About Us

Plant Introductions, Inc., (PII) was established in 2007 by the owners Mark Griffith, Jeff Beasley, and Mike Dirr. We converted an abandoned hog farm into a facility to breed, select, evaluate, and develop new ornamental plants. We are currently breeding and evaluating thousands of seedlings and selections in dozens of genera. We evaluate our plants in containers and in the ground before making the final decision whether or not to introduce a new plant. Our goals are to serve the nursery industry by developing plants that require less inputs during production and to serve the end user (gardener, homeowner, etc.) by developing plants that perform in the landscape. Disease resistance, compact habit, extended flowering period, and continuous color (from flowers, foliage, and stems) are desirable traits for most of the plants we work with. We strive to achieve these goals by developing and introducing only superior garden plants that perform as promised.

PII is a dedicated plant breeding, evaluation, and introduction company. We are not open to the public and we do not sell plants. If you are a grower interested in purchasing liners, then please contact:
