High diversity monarch seed mix

Project

The Iowa State University Monarch Research Team developed this seed mix for research purposes. The mix includes three milkweed species. Milkweed is the only host plant for monarch caterpillars. The mix also contains nectar-producing species that benefit butterflies as well as many pollinators, such as bees. All species are perennials native to Iowa.

Grass species included in the mix are mostly short to medium height in order to reduce competition with forbs. The plant species were selected to perform in well-drained and moderately well-drained soils. Adjustments may be necessary for wet soils. Iowa State reserves the right to alter this mix as needed depending on research results. Pure Live Seed (PLS) indicates the amount of seed that is capable of developing into seedlings.
