I spent about $450 two years ago on a good amount of seed for prairie wildflowers & grasses \that I want my land filled with instead of giant foxtail and canary reed. I chose 5 plots across the land to cut to dirt and spread the seed mixed with a substrate of manure. Ideally they'd all bloom and spread seeds from their sections. A few of the plots have shown life, but not all. I have gone out and collected some of the seeds to help spread around. I'm hoping to see the second season version of some of those this year. Come on Rattlesnake Master!!!!
there is quite a bit of knowledge and technique to prairie restorations.
and aside from that if you are talking about wildflowers many of them will not do that well in good soil because they cannot outcompete other plants that will do better. they do better in poorer soils or specific places they've acclimated to for those reasons, because other plants can't do as well.
some plants may need soil disturbance and/or fire to get going again, some may take several years to get big enough or only bloom once every other season.
these are the kinds of things that take some time to research, but it can be a fun thing to do.
any chance you can figure out how to get the plants to grow in pots then you can take those specimens and plant them out after a few seasons when they have a bigger root system and they can survive a bit more competition instead of trying to get a seed to grow and survive in the competition. and of course deeper taproot plants will need taller pots.
i don't really like seed blends because i've gotten burned rather badly by a few that have cost me hundreds of hours of weeding to get the introduced plants under some kind of control (and it's not even close to being finished) and also some seed blends are not clean of other weed seed contamination so you can end up with things you really don't want at all.
