FL3865A - Upland Blend Wildflowers
The Upland Blend Wildflowers include fifteen wildflower species that are native to the area surrounding the Rocky Mountains. This blend will perform beautifully wherever the summers are hot and the winters are cold, but the species are native to regions farther away from the coast. The glorious colour will change as the blend blooms over a long season, supporting local bees and other pollinators. This is a blend of very cold hardy annuals and perennials that will return year after year, blooming from early summer into the fall. Plant in any inland area, from the foothills to the valleys, from central Oregon up to Jasper National Park.

How To Grow
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.
