Many of our species are produced from MITOSIS seed. MITOSIS is the Montana Interagency Tree and Shrub Improvement Study. The study was a cooperative effort to evaluate the performance of various species of plants in established Montana plantings. The selected plantings were evaluated for over ten years and the best performing plants were selected for seed orchard establishment at the nursery.
We use this seed source whenever possible. These selections perform well in many of Eastern Montana's variable and harsh climates. Although these plants have not been tested in every environment, MITOSIS selections are some of the best plant materials available for use in Montana. The selections are proven to survive in Montana because they were evaluated in Montana not other Northern Great Plains states.
