PLS stands for Pure Live Seed, an industry-standard measure of seed quality. It reflects the portion of seed in a batch that is viable and capable of germinating.

What this means for you: when you purchase 1 lb. of PLS seed, the physical weight of the seed you receive will be slightly more than 1 lb. That’s because we account for non-viable seed and natural inert material upfront, so you receive a full pound of live, plantable seed.

Many companies sell bulk seed by total weight, which can include filler and non-viable seed. By pricing based on PLS, we make sure you’re getting exactly what you paid for—high-quality native seed with more predictable, successful germination.

Seeds & Seed Mixes:

Seeds and seed mixes ship nationwide, year-round, typically within 3–5 business days. If you need to postpone a seed mix shipment until fall, please note this in the order notes at checkout.

Live Plants:

Live plants are available year-round while inventory lasts and ship to select Midwest states due to plant health and hardiness considerations. After your order is placed, we’ll contact you to coordinate a spring shipping window, as many plants are overwintered and ship once dormancy breaks.

States we ship live plants to:
Missouri, Minnesota, South Dakota, North Dakota, Nebraska, Kansas, Oklahoma, Arkansas, Tennessee, Kentucky, Illinois, Indiana, Ohio, Michigan, and Iowa.

Live Stakes:

Live stakes are available by request only and must be ordered by submitting a contact form. Ordering is open seasonally from November 1 through February 28.

Live stakes ship to the same select Midwest states as live plants due to establishment requirements.
