The wildflowers in this blend are native to the plains if south-central Canada and the northern United States. They have been specially selected for the Southern Prairies Wildflower Blend. These North American native species thrive in landscapes with cold winters and hot summers, and they once occurred in abundance, mixed with a host of drought tolerant wild grasses. From the bright yellow of Partridge Peas to the intense fiery reds of Indian Blanket, punctuated by the vivid purple of Prairie Aster, this blend looks spectacular in its native landscape, but also in exposed areas on the coast. None of the components are invasive, and all are approved for planting in home gardens.

We recommend planting in early spring when the ground is still cool and wet.

Please review the list below for the seeds that are included in our Southern Prairies wildflower blend. These flowers will thrive in most garden settings, but they have been selected due to their performance in the North American Plains. By that we mean from the foothills of the Rocky Mountains east to the Great Lakes. They will also grow perfectly well in coastal gardens. This is a beautiful and diverse mix of flowers both short and tall.

Direct sow early March to the end of May. Wildflower seeds can also be sown in the autumn, but you may lose a certain percentage of seeds to water, birds, and animals. To make the most of the annual species, direct sow in March.

If there are no plants (including weeds) growing in the site you want to plant, there may be a problem with the soil. Possible issues may be soil fertility, lack of drainage, or the need for soil amendments to improve texture. In such spots (eg, beneath a cedar tree), few plants will thrive, including wildflowers.

Remove as much existing vegetation as possible through pulling or tilling under in order to minimize competition. Loosen the soil by scraping, raking, or tilling. Wildflower blends will not usually take if planted into existing lawn because the thatch prevents their contact with soil.

In small areas, seeds can be scattered by hand. In larger areas, you may want to employ a lawn spreader or some other mechanical means. We recommend adding 1-2 parts clean, dry sand to 1 part wildflower seeds which will help the seeds spread evenly. Do not use beach sand, as it usually contains salt. It may be wise to spread most of the seed, but to save some for filling in bald spots at a later date. Seeds must come into contact with the soil in order to germinate. Do not bury seeds more than 2-3 times their thickness.

Aim for a planting density of 70 seeds per square foot. 90g of seeds will cover 1,000 ft². Use 4kg per acre. 500g covers about 5,500 ft². If you are seeding an area where site preparation and weeding are not possible, double this rate.

Keep the seeded area as evenly moist as possible to help the seeds germinate and the young seedlings become established. Weeds need to be kept under control. Once they are growing, most mixes will not require additional water except in long periods of hot, dry weather. All of our mixes should re-grow for several years, but will benefit from re-seeding. In late summer, many of the components will produce seed heads that can be harvested and replanted the following spring.
