for Medium to Medium-Dry Soils
Often during construction, bulldozers remove the topsoil and organic matter, leaving exposed clay that can present harsh conditions for plant growth. The tough species in this seed mix, including Purple Coneflower, Yellow Coneflower, Wild Bergamot and Big Bluestem, all in the corresponding picture, are up to the task.

Once established, the deep root systems on the tough native perennials chosen for this mix will need no water or other care during times of drought or brief flooding, where other species would fail in these challenging conditions. Although some of the native plants in this seed mix have ranges that extend beyond zones 3-7, the majority will do best in this zone range. For more detailed information please see the RANGE MAP for each species. View the complete species list, including % by weight, under COMPONENTS.

For seed mixes of 1/8 acre or less, we include a temporary cover crop at no additional charge. ReGreen is a sterile, short-lived perennial wheat hybrid that can be planted spring or fall.

Add a Seed Mix Enhancement for that extra splash of color!

Establishing a native plant community from seed can take 3 years or more - learn more.

All mixes are subject to change without notice depending on availability of species.

3 Questions asked on Tallgrass Exposed Clay Subsoil Seed Mix

Ask a Question

Q tracey • October 21 Can I substitute the tall grasses for shorter ones such as little bluestem and prairie dropseed for example?

A Prairie Moon • October 23 Hi Tracey, Good question! Any substitutions would make it a custom mix. If your order will be for $200 or more, we offer free custom mix design. You can learn more here.

Q Lorna • April 3 Are there any seed mixes designed to work in hardiness zone 3 or 4?

A Prairie Moon • April 3 Thanks for asking Lorna! Our pre-designed native seed mixes are designed to perform well from the Midwest to the Northeast, primarily in zones 4-6. However, there is flexibility, and planted with the right sun exposure and soil moisture, our mixes, including Tallgrass Exposed Clay Subsoil, can do well in zones 3-7.

Q Anna • February 9 Do I need to do anything to prepare the seeds before planting?

A Prairie Moon • February 10 Hi Anna. If the site is prepared and the weed seed bank is as exhausted as possible, the seed in the Tallgrass Exposed Clay Subsoil mix is ready to be sown.

Native plant communities provide the inspiration for our seed-mix designs. All our mixes feature high seeding rates and a diverse balance of native species, which, when mature, will provide blossoms throughout the year. No matter what you want from a seed mix, you will need to make sure it fits the soil-moisture holding capacity and sun conditions of your site.

E stablishment of the diverse native-plant communities represented in our seed mixes can take three to five years. The most critical process before planting is preparing the site by removing unwanted species and working to deplete the soil’s weed seed bank.

PLANTING INSTRUCTIONS FOR HAND SOWING A NATIVE SEED MIX

*PLEASE NOTE: we are a mail order nursery and have no retail facilities, but you may pick up your order if prior arrangements are made. Pick up orders are subject to **MN Sales Tax.

Shipping & Handling Charges:

SEED $100.00 and under: $5.00
Retail SEED orders over $100.00 ship free! Custom seed mixes or wholesale seed sales over $100, add 5% of the total seed cost
(for orders over $1,000 a package signature may be required)

BARE ROOT and POTTED PLANTS $50.00 and under: $9.00
over $50.00: 18% of the total plant cost. (For orders over $1,000 a package signature may be required.)

TOOLS and BOOKS have the shipping fee included in the cost of the product (within the contiguous US).

**We are required to collect state sales tax in certain states. Your state's eligibility and % will be calculated at checkout. MN State Sales Tax of 7.375% is applied for orders picked up at our MN location. Shipping & handling charges are also subject to the sales tax.

Shipping Season:

SEED, TOOLS and BOOKS are sent year-round. Most orders ship within a day or two upon receipt.

BARE ROOT PLANTS are shipped during optimal transplanting time: Spring (April-May) and Fall (Oct). Some ephemeral species are also available for summer shipping. Since our plants are field-grown, Nature sets the schedule each year as to when our season will begin and end. We fill all orders, on a first-come, first-serve basis, to the best of our ability depending on weather conditions beyond our control.

POTTED PLANTS (Trays of 32/38/50 plugs and 3-packs) typically begin shipping early May and go into June; shipping time is heavily dependent on all the species in your order being well-rooted. If winter-spring greenhouse growing conditions are favorable and all species are well-rooted at once, then we ship by order date (first come, first serve). We are a Midwest greenhouse, and due to the challenges of getting all the species in the Mix & Match and Pre-Designed Garden Kits transit-ready at the same time, we typically can't ship before early May. Earlier shipment requests will be considered on a case-by-case basis.

*We are unable to ship PLANTS (bare root or potted) outside the contiguous US or to CALIFORNIA due to regulations.

Delivery:

We ship using USPS, UPS and Spee Dee. UPS and Spee Dee are often used for expediting plant orders; they will not deliver to Post Office Box numbers, so please also include your street address if ordering plants. We send tracking numbers to your email address so please include it when you order.
