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.

Rough blazing star (Liatris aspera) has rounded clusters of purple flowers spaced along upright stems in late summer and early fall. The separated flower heads give the stalk a different appearance from blazing stars with tightly packed spikes. Narrow leaves cover the stem below the flowers.
Plant it in full sun with average to dry, well-drained soil. This is a useful choice for a dry prairie garden or an open, lean-soil planting. Its flowers can stand above lower foliage without requiring a large, bushy crown.
Small offsets may develop near the parent plant, gradually producing a group of flowering stems. Leave those groups among other plants that suit the same sunny, well-drained ground. Bees and butterflies visit the flowers, and birds can use the mature seed. The flower stalks can remain after bloom rather than being removed immediately.

Button Blazing Star is a medium to tall prairie forb with distinctive flower spikes dotted with large buttons of clustered violet florets that bloom beginning in July. A favorite of bees, butterflies, and other pollinators, this blazing star favors dry sites and lean soils. It is very drought tolerant once established but may be consumed by rabbits and rodents particularly overwinters with tight food resources.

Plant Shipping & Care
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 online orders: Plant and seed orders ship only, except eligible trees and shrubs offered for pickup. Shipping charges are calculated at checkout.
- Retail pickup — trees and shrubs only: Pickup is available by prior arrangement for eligible woody plants. Some container options are offered for scheduled pickup only. Check the selected product option and the cart pickup instructions before ordering. Pickup and shipped items require separate orders.
- Wholesale orders: Plants, trees and shrubs are available for pickup by arrangement. Delivery can also be arranged for your order. Wholesale pickup is free. All seed orders ship, including wholesale seed.
- Pickup locations and dates are confirmed by email. Please wait for confirmation before traveling to a pickup site. Our offices are not retail stores or nursery pickup locations.
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
- Plant pickup and delivery are arranged for your order. Seed ships only.
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
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
