The Arboretum was dedicated on October 7, 1992 as part of an International Larix Symposium to provide opportunities for species comparisons and genetics research. Species from North America, Asia, and Europe were planted, along with subspecies and hybrids. The Arboretum is organized as three equal-sized blocks, each about 70 by 230 feet (21 by 70 m), with 12 trees of each species, subspecies, and hybrids in each of the three blocks, for a total of nearly 600 trees.
The species planted are European Larch (Larix decidua), Dahurian Larch (Larix gmelinii), Japanese Larch (Larix kaempferi), Tamarack Larch (Larix laricina), Subalpine Larch (Larix lyallii), Masters' Larch (Larix mastersiana), Western Larch (Larix occidentalis), Chinese Larch (Larix potaninii), and Siberian Larch (Larix sibirica). Himalayan Larch (Larix griffithii) was also to be planted but seed could not be obtained.
Hybrids planted include L. decidua x L. kaempferi (Larix x marschlinsii; Dunkeld Larch), L. lyallii x L. occidentalis (Bitterroot Larch), and L. occidentalis x L. lyallii (Bitterroot Larch, reverse cross).
