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.

Showy tick trefoil grows upright or occasionally sprawls in sunny, moisture-retaining ground. Its leaves may develop powdery mildew, a useful expectation when placing it in a formal border.

For Desmodium canadense, choose full to partial sun and moist to mesic soil. Recorded habitats include moist to mesic black-soil prairies; Moist riverside meadows; Lake margins; Thickets; Limestone glades. Reported height: about 3 ft.

Its below-ground structure is described as taproot. Choose the permanent location with that root structure and the mature size in mind. Planning the surrounding space at planting time reduces the need to reorganize an established bed later.

Plant characteristics

Desmodium canadense (Showy Tick Trefoil) is a common plant of many prairie restorations and native landscapes because it is quite showy, but also because it fixes nitrogen increasing soil health improving the ecosystem. It is named for its showy flowers yes, but also from it seed pods sticking (Tick) to animal fur and the occasional human passer.  It is quite an ingenious seed dispersal mechanism, just like nature to find the most clever way to make it happen :)

Supplementary Illinois preserve records

Recorded Desmodium canadense 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.

Bees & other flower visitors

USGS observations recorded the following insects visiting flowers of this plant in Minnesota. The records describe visits, without distinguishing pollen collection from nectar feeding or measuring successful pollination. They do not establish local occurrence, exclusive dependence, or a larval-host relationship.

Bees

  • Bombus sp. (genus only) — Minnesota; 2016.

Caterpillars & other plant-feeding insects

This plant has published caterpillar host records for the butterflies and moths listed below. These are larval feeding relationships, separate from adult nectar visits. The records span a North American literature compilation and do not establish that every insect occurs locally or uses only this plant.

Butterflies & skippers

  • Epargyreus clarus — Silver-Spotted Skipper
Show / hide ▾Frequently asked questions

What are the ideal growing conditions for Showy Tick Trefoil?
Desmodium canadense performs best in partial sun to full shade with mesic to dry-mesic (prairies, savannas & thickets) conditions. It thrives in authentic regional soil types ranging from sandy loam to well-drained clay loams.

How do I germinate and establish Showy Tick Trefoil from seed?
Seed of Desmodium canadense has a germination code of C(30). For best results, sow seed in late fall/winter for natural outdoor freeze-thaw stratification, or cold-moist stratify in refrigeration for 30 to 60 days before spring indoor propagation.

Is Showy Tick Trefoil 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 Showy Tick Trefoil 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
