Plant Collections Home Page

There are currently over 5,000 living specimens with individually assigned accession numbers at the Iowa Arboretum. Some strengths of the collections include oaks, hardy pecans, dwarf conifers, maples, irises, and hostas. The location designation of several specimens, and in some cases entire species, are according to plant type and primary and secondary inventory.

As outlined in our mission statement, one purpose of the Iowa Arboretum is to be an inspiring educational resource of trees, shrubs, and other plants in the Iowa landscape. Interpretative collection signage achieves part of that mission. Individual plant labels also provide valuable information including genus, species, and cultivar information and an indication of the age of the planting.
