Des Moines’ climate, characterized by hot, humid summers and cold, snowy winters, presents unique challenges and opportunities for local gardeners and environmental enthusiasts. One effective strategy to enhance our urban landscape and support local biodiversity is the incorporation of native plants into our gardens and public spaces.
Understanding Des Moines’ Climate
Des Moines experiences a humid continental climate (Köppen Dfa), with average high temperatures reaching 86°F (30°C) in July and dropping to average lows of 17°F (-8°C) in January. Annual precipitation averages around 36.55 inches, with snowfall averaging 36.5 inches per season. These conditions influence the types of vegetation that thrive in our region.
Benefits of Native Plants
Native plants are species that have evolved in a specific region over thousands of years, adapting to local climate, soil, and wildlife. Incorporating native plants into our landscapes offers several advantages:
- Environmental Adaptation: Native plants are well-suited to Des Moines’ climate, requiring less water and maintenance compared to non-native species.
- Support for Local Wildlife: They provide essential food and habitat for native pollinators, birds, and other wildlife. For instance, milkweed is crucial for the survival of monarch butterflies, serving as the sole host plant for their larvae.
- Soil Health and Erosion Control: Deep root systems of native plants improve soil structure and prevent erosion, contributing to healthier urban ecosystems.
Local Initiatives Promoting Native Plant Use
Several local organizations and initiatives are championing the use of native plants in Des Moines:
- Plant Iowa LLC: Founded in 2025, this native plant nursery focuses on local ecotype seeds and creating pollinator gardens. They aim to restore homeowners’ landscapes with native plants, making them accessible to the public.
- Sprout Garden at Drake University: This urban youth learning garden educates visitors on the importance of native plants, highlighting their role in reducing maintenance costs, improving air and water quality, and increasing biodiversity.
- Community Roots at Franklin Avenue Library: A permanent display featuring a large prairie root specimen educates visitors on the significance of native perennial plants in Iowa’s landscapes.
Getting Involved
Residents interested in incorporating native plants into their gardens can start by:
- Visiting local nurseries like Plant Iowa LLC to select appropriate native species.
- Participating in community workshops and events focused on native gardening.
- Consulting resources provided by local organizations to learn about plant selection and maintenance.
By embracing native plants, we can create resilient landscapes that support our local environment and wildlife, contributing to a healthier and more sustainable Des Moines.
