Pure Live Seed
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.

Plant characteristics
Oxalis violacea, commonly known as Violet Wood Sorrel, is a delicate native wildflower prized for its charming purple-pink blooms and clover-like foliage. This low-growing perennial thrives in woodland settings and shaded garden spaces, bringing natural beauty to naturalized areas and shade gardens. The plant produces dainty flowers that attract pollinators while its compact growth habit makes it ideal for ground cover applications. Hardy and low-maintenance, Violet Wood Sorrel establishes well in moist, well-draining soil and partial to full shade. Perfect for native plant enthusiasts looking to support local ecosystems and create authentic woodland gardens.
- Flower Color cream to green
- Flower Time April, May, June

Illinois plant communities
Mesic black-soil prairie — central Illinois
Recorded at Prospect Cemetery Prairie (Ford County), Weston Cemetery Prairie (McLean County). INHS identifies these sites as remnants of this community.
Selected native plants from the same remnant records:
- Sorghastrum nutans
- Andropogon gerardii
- Sporobolus heterolepis
- Eryngium yuccifolium
- Silphium laciniatum
- Parthenium integrifolium
These inventories include edges and disturbed patches. Shared remnant records do not establish that every plant grows together in one microsite.
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.
- Prairie and open-grassland associates (Tallgrass prairie region; account synthesis): Sporobolus heterolepis.

Show / hide ▾Frequently asked questions
What are the ideal growing conditions for Violet Wood Sorrel?
Oxalis violacea performs best in full sun with dry-mesic (open oak woodlands, prairies & glades) conditions. It thrives in authentic regional soil types ranging from sandy loam to well-drained clay loams.
How do I germinate and establish Violet Wood Sorrel from seed?
Seed of Oxalis violacea 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 Violet Wood Sorrel 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 Violet Wood Sorrel 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.

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
