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.

Canada wild rye grows during cooler seasons and is relatively short-lived. It can provide early growth while slower perennial neighbors establish.

For Elymus canadensis, choose full to partial sun and dry to moist soil. Recorded habitats include dry to wet-mesic prairies; Sandy woods; Oak openings and thickets; Lakeshores; Sand dunes; Riverbanks. Reported height: 36–60 in.

Growth habit: robust grass that readily reseeds itself. Allow space for this growth between neighboring plants over several seasons, rather than spacing only for the size of a young plant.

Plant characteristics

A cool season clump forming grass, Canadian Wild Rye features bluish green to green leaves that clasp its stiff stems. The robust nodding seedheads resemble rye and are held above the foliage for a pretty ornamental effect especially in a breeze. This adaptable grass can be found in prairie to savanna situations in moist to dry conditions.

    Other regional plant communities

    These plants are named with this species in published vegetation accounts. Each list keeps its community and region; some records describe a shared vegetation type rather than neighboring plants in a measured plot. They are ecological records, not a planting recipe, and may include plants unsuitable for a particular garden.

    Supplementary Illinois preserve records

    Recorded Elymus canadensis at Loda, Prospect, Weston. The plants below occur in the same named preserve inventories. This is evidence of shared preserve occurrence, not proof that every pair grows together in one microsite.

    These mesic black-soil prairie inventories are from central Illinois: Loda (Iroquois County), Prospect (Ford County) and Weston (McLean County). They include introduced plants and are not county-nativity lists or planting recommendations.

    Show / hide ▾Frequently asked questions

    What are the ideal growing conditions for Canada Wild Rye?
    Elymus canadensis performs best in full sun with mesic to dry-mesic (prairie borders & 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 Canada Wild Rye from seed?
    Seed of Elymus canadensis has a germination code of Code A (no pre-treatment required). Seeds can be sown directly in spring into warm, prepared soil.

    Is Canada Wild Rye 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 Canada Wild Rye 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.

    Plant Shipping & Care

    We want to ensure that our customers get what they want, a native backyard oasis. To do that, we need to follow a few simple guidelines and give you some information and pointers to make sure you get your plants delivered in a healthy state.

    As a reminder, you will receive an email to confirm your pickup or shipping window just before the plants are ready. See Order Fulfillment below for seasonal fulfillment windows.

     

    Choices to Receive Your Plants & Accessories

    • Retail - We only offer shipping & shipping is calculated at check out*
      • We do not offer retail pick up
    • Wholesale - Delivery is customized based on order size and location
    • Wholesale - Pickup is free

     

    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

            • Unpack your order IMMEDIATELY
            • Inspect for damage and report any issues immediately to Natives@NaturalCommunities.net
            • Water your plants
            • Install your plants as quickly as possible and water the entire garden area thoroughly
            • If you cannot install your plants immediately
              • Some plants may not be in a container, put them into some kind of a container such as a paper cup with loose soil until installation
              • Make sure each plant is receiving the appropriate amount of light.
              • Continue to water daily each morning and possibly again in the afternoon
              • No additional fertilizer is needed

            Seed Shipping & Care

            There is a minimum order requirement of $30 for each seed species. Seed ships all year and typically ships within a week of an order being placed.

            We have attempted to put together some basic information regarding native seed installation, establishment, and maintenance.  We hope you find it helpful.  If you need further assistance on native seed establishment, please schedule a free consolation call here.
