Pure Live Seed

Seed is provided in Pure Live Seed (PLS) unless otherwise stated.

Pure Live Seed (PLS) refers to the percentage of a seed lot that consists of the desired species and is viable (capable of germination).   

Here's why PLS is crucial for native seeds:

  • Accurate Planting:
    • PLS helps determine the actual number of viable seeds in a given weight or volume of seed.   
    • This ensures you plant the correct amount of seed to achieve the desired density and success rate.   
  • Cost-Effectiveness:
    • By knowing the PLS, you can avoid overspending on seed that may not germinate.
    • This is especially important for native seeds, which can be more expensive than some cultivated varieties.
  • Weed Control:
    • PLS helps minimize the presence of weed seeds within the seed lot.
    • This reduces competition for resources and ensures the successful establishment of the desired native plants.
  • Ecological Restoration:
    • Using high-quality native seeds with a high PLS is essential for successful ecological restoration projects.
    • It helps to re-establish diverse and resilient plant communities that support local wildlife.

Botanical Profile & Ecological Characteristics

Sorghastrum nutans plays a critical role in establishing healthy, diverse native plant communities throughout the Midwest. Adapted over thousands of years to regional climate patterns, seasonal temperature extremes, and variable moisture conditions, it develops a resilient root architecture (deep taproot system (18"+ depth)) that builds soil organic matter, improves water infiltration, and resists environmental stress.

This classic "tallgrass prairie " plant can grow to great heights.  Named Indian grass because it is reportedly associated with Native American camps, probably from the disturbance of food cultivation and from its residents.  It is a majestic plant, but it can be aggressive in small landscape settings.

  • Sun Exposure Prairie/Savanna
  • Soil Conditions Wet Mesic, Mesic, Dry-Mesic 
  • Height 4'-6'
  • Flower Color green
  • Flower Time August, September, October
  • Faunal Associations & Specialist Wildlife Support

    As a vital resource in native ecosystems, Sorghastrum nutans provides essential sustenance across multiple trophic levels:

    • Larval Host & Pollinator Support: Pepper and Salt Skipper (Amblyscirtes hegon) & Common Roadside Skipper.
    • Specialist Floral Visitors: Common Roadside Skipper (Amblyscirtes vialis), Delaware Skipper (Anatrytone logan), Native Songbirds (High-Calorie Winter Seed Heads), Bumblebee Queen Nesting Microclimate.
    • Avian & Insect Forage: Flowers provide dense, accessible nectar and pollen during the peak growing season, followed by nutritious seed heads that feed native songbirds and overwintering wildlife.

    Native Plant Associates & Community Ecology

    In authentic Midwestern habitats—such as Mesic Tallgrass Prairies, Savannas, Prairie Borders—Sorghastrum nutans naturally co-occurs and establishes balanced, biodiverse communities alongside:

    Landscape Applications & Restoration Guidelines

    Sorghastrum nutans is well-suited for home landscaping borders, rain gardens, naturalized meadows, and conservation acreage alike.

    • Plug Spacing: Space live plugs approximately 18" to 24" on-center for optimal crown development and contiguous ground coverage.
    • Broadcast Seeding Rate: 1.50 – 3.00 lbs/acre PLS (when included in diverse prairie seed mixes).
    • Regional Provenance: Sourced and propagated from regionally adapted Midwest ecotypes for maximum ecological fitness and cold hardiness.

    Frequently Asked Questions (FAQ)

    What are the ideal growing conditions for Indian Grass?
    Sorghastrum nutans performs best in full sun with mesic to dry-mesic (tallgrass prairies & open savannas) conditions. It thrives in authentic regional soil types ranging from sandy loam to well-drained clay loams.

    How do I germinate and establish Indian Grass from seed?
    Seed of Sorghastrum nutans has a germination code of Code A (no pre-treatment required). Seeds can be sown directly in spring into warm, prepared soil.

    Is Indian Grass deer and herbivore resistant?
    Yes. Native plants adapted to Midwestern habitats naturally produce protective secondary compounds and fibrous textures that make them highly resistant to deer, rabbits, and other grazing herbivores.

    When should I expect Indian Grass to emerge and bloom?
    Established plants break dormancy in spring as soil temperatures warm, developing vigorous foliage before blooming in their seasonal window to provide vital nectar when native pollinators need it most.

    Order Fulfilment - When Your Plants or Other Items Will Be Ready

    We take orders all year long and seed is shipped all year, but we only provide the plants to you in certain fulfillment windows to ensure healthy plants.

    Wholesale Orders

    • Shipped or are Ready For Pick Up As Requested.

     

    Retail & Website Orders

    • Seed Typically Ships Out Within One Week Of Order All Year Long
    • Typically, single species flats ship when ready, sometimes as soon as early to mid-April (depends on weather) through early-October.
    • Mixed species kits are batched and shipped as indicated on the product page.
    • If a plant order is placed while outside of the plant fulfillment window your plants will be reserved through your payment, however, the order will not be fulfilled and shipped until the following spring. We don't want to provide you plants when they won't be happy during the cold winter months. 
    • Early in the spring and later in the fall certain species may be dormant or partially dormant with brown leaves, however they will return to grow healthy next growing season.
    • Your order may arrive in several different shipments.
    • If certain plants within an order will not be available until a later date, we may choose to hold the full order until all are ready.  In certain circumstances, we may choose to send them in two separate shipments 
    • Fulfillment is always dependent upon plant availability.  We try our best but sometimes plants do not overwinter well and perish.  If a plant is on back order you will receive an email indicating the estimated shipping date.  If we can not provide the plant we will first notify you and give you an option of substitution or a refund of that individual species.
    • Plants are typically only packaged and shipped on Mondays to ensure they do not sit in the harsh delivery facility for extended periods of time over the weekend. You will receive a confirmation email once your delivery has been shipped and to estimate your delivery date.
    • Apparel & accessories are ready typically within one to two weeks. See product page for holiday shipping.

    Where We Ship

     

     

          What to Expect When Receiving Your Delivery

          • Your plants will be packaged with the utmost care
          • We will need to cut back certain plants prior to shipping. This seems counter-intuitive, however, the fewer leaves the less water the plants can lose during shipping, resulting in healthier plants for you. This also enables the plants to fit within the protective packaging and shipped safely.

           

             Shipments

            • Larger plant shipments will look similar to the picture below with a tray of your plants and a cardboard box to protect them during shipping.

             

             

            What to Do With Your Plants After  Receiving Your Delivery
