Pure Live Seed
Pure Live Seed
Seed is provided in Pure Live Seed (PLS) unless otherwise stated.
Pure Live Seed (PLS) expresses the viable seed content of a seed lot using its purity and germination or viability test results. It helps you compare seed lots and calculate how much bulk seed is needed to meet a specified PLS planting rate.
PLS weight and bag weight
PLS weight is not the same as the total weight of seed in a bag. For example, a lot with 80% purity and 75% viability contains 60% PLS: 80 × 75 ÷ 100 = 60. Supplying 10 lb PLS from that lot requires about 16.67 lb of bulk seed.
Use the current seed test and the stated basis of the mix specification. Germination calculations may include applicable hard or dormant seed. Seed-count estimates also require the number of seeds per pound; PLS alone does not provide a seed count.
What to check when buying a mix
Check whether each rate is stated in PLS pounds, bulk pounds, or a combination. A mix with both bases should not be described as having an all-PLS total.
PLS does not remove weed seeds or guarantee establishment. Review the seed label and analysis for weed content, and match site preparation, planting conditions and follow-up management to your project.

James' sedge stays low, with leaves that remain through summer. Its spreading clump fits partial light or shade in fertile woodland soil.
For Carex jamesii, choose partial sun to moderate shade and mesic soil. Recorded habitats include rich mesic woods, especially maple-basswood; Wooded slopes. Reported height: flowering stems about 2–4 in; leaf blades up to 7 in long.
Growth habit: dense tufts; spreads mainly by reseeding and forms low spreading clumps in relatively open sites. Allow space for this growth between neighboring plants over several seasons, rather than spacing only for the size of a young plant.

Plant characteristics
This sedge looks like mini tussocks of grass in woodlands and can provide nice ground cover between stepping stones when planted densely. Carex jamesii (Grass Sedge) can do well in deep shade as it develops early in the spring and blooms before the canopy trees have fully developed their leaves. Carex jamesii (Grass Sedge) is one of the best native sedge for those difficult to establish shady areas

How these records were selected
To reproduce this selection, use the “UDELep May 2025” worksheet in the original research dataset.
- Match the insect record IDs above to column A (UDLepID). Within each table row, pair every listed insect ID with every listed source plant name.
- Use the first two words in column H for the insect’s scientific name, column E for its common name, and column AB for its source category.
- Treat the selected pairs as reported caterpillar host records. Keep all other source fields unchanged and outside this selected table. Include no other rows or host pairs.
- Group butterflies and skippers together, and the other categories as moths. Retain the source’s exotic-category labels and sort display names by scientific insect name.

- 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
Natural Communities ships native plants and seed from multiple supplier locations across the Midwest. Shipping coverage extends beyond our local consultation area; see the shipping map below. Availability and delivery options depend on the product and destination. Check the product details and shipping options at checkout, or contact us before ordering if you need help confirming coverage.
Our on-site ecological consulting serves the greater Chicago region and southeastern Wisconsin, including the Milwaukee area. Consultations take place at your property by appointment. Our offices are not walk-in retail stores or plant pickup sites.

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
