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.

Glade Fern (Homalosorus pycnocarpos, formerly Diplazium pycnocarpon) adds long, narrow, arching fronds to a shaded planting. It prefers steady moisture and soil rich in organic matter, with drainage around its rhizomes. Colonies can develop over time, while prolonged dryness can brown the foliage; a sheltered woodland bed is a useful starting point for siting it.

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.

Diplazium pycnocarpon, commonly known as Glade Fern, is an elegant native perennial fern valued for its tall, upright fronds and refined, finely textured appearance. The plant forms a graceful clump of arching, bright green foliage that brings softness and structure to shaded woodland gardens and naturalized landscapes. Glade Fern thrives in moist, rich, well-drained soil and prefers partial to full shade, though it can adapt to a range of shady conditions when moisture is consistent. Its distinctive form and reliable habit make it an excellent choice for adding a polished, natural look to shaded garden settings.

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
- Website orders: Seed, plugs and bare-root plants offered for shipping are shipped to your address. Shipping charges are calculated at checkout.
- Container trees and shrubs: Some #3 and #5 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 where indicated in the cart.
- Wholesale orders: Delivery and pickup are arranged separately according to the order, supplier yard and location. Wholesale pickup is free.
- 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
- 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
