Sixteen species of wildflowers that are native to the plains if south-central Canada and the northern United States have been 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 dramatic blue of Beardtongue, 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. Recommended seeding rate: 225g per 1,000 square feet. We recommend planting in early spring when the ground is still cool and wet.

Unless otherwise stated, all the wildflower mixes will contain perennials, annuals, and biennials. 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 will be full of salt. It may be wise to spread most of the seed, but to save 15-20% 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. Follow along with this handy guide how to grow wildflowers in your garden and grow some colour!
Season & Zone
Exposure: Full sun to partial shade
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.
Site Selection: If there are no plants (including weeds) growing in the site you want to plant, it is unlikely to support wildflowers. Possible issues may be soil fertility, lack of drainage, or the need for soil amendments to improve texture.
Site Preparation: 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.
Seed Application: 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.
Planting rates: 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.
