Description

June Grass (Koeleria macrantha), also known as prairie Junegrass, is a compact native bunchgrass commonly found in prairies, rocky slopes, and dry open landscapes across much of North America. This cool-season grass begins growing early in spring, bringing fresh green color to prairie plantings before many warm-season grasses emerge.

By early summer, June Grass produces narrow, upright seed heads that start with a soft green to silvery tone and gradually mature to tan. These seed heads add fine texture and movement to prairie landscapes while providing food for birds and wildlife.

June Grass thrives in full sun and prefers well-drained soils, including sandy or rocky sites where many other grasses struggle. Its drought tolerance and tidy growth habit make it a valuable species for prairie restorations, dry landscapes, and naturalized plantings.

Seeds & Seed Mixes:

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

Live Plants:

Live plants are available year-round while inventory lasts and ship to all states except California, Arizona, Oregon, Washington, Nevada, Alaska, and Hawaii. 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.

Estimated shipping for 2026 plant orders begins in mid-April, weather permitting.

If you’re looking to secure plants in advance or need larger quantities for a project, we offer contract growing options. Contact us to discuss your needs and request a quote. Additional species not listed online may also be available through contract grow.

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. A minimum of 100 stakes per order is required, with at least 25 stakes per species.

Live stakes ship only to the following states: Missouri, Minnesota, South Dakota, North Dakota, Nebraska, Kansas, Oklahoma, Arkansas, Tennessee, Kentucky, Illinois, Indiana, Ohio, Michigan, and Iowa.

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.
