Wildflower stratification question

If wildflower seeds requiring stratification are scattered in the spring, will they still come up the following spring?  I had some mixes I didn't get in last fall due to irrigation problems.  I went ahead and scattered them this spring, but I'm sure there are varieties that require stratification.  Will those come up next year or will going through a spring\summer "ruin" the seeds somehow?

Thanks in advance.

How would mother nature spread these seeds? when would she spread them? Those are the prime questions to always ask when dealing with seeds.

Nature doesn't wait usually, if she does then the seeds would remain in their "pods" until the time was right for them to be planted.

Cone flowers are a good example, as are most of the nut trees. The seeds are released in the fall and they overwinter on or in the soil, the next spring they germinate and grow.

Stratification is man's way of doing what nature does automatically, it is an attempt at giving seeds their "winter chill", this can be done artificially (stratification) or naturally (plant in the fall and let winter be the cold storage).

I was able to find the answer in a a guide on Prarie Moon's site.  Sounds like at least some of them will.

If seed is sown untreated in the spring, some species will not germinate until the following spring after wintering over.

It's always great to find documentation after you've done something.  On the other hand, if I'd had it I might have been to intimidated to take on the project.  This year was really optimal as far as weed conditions go.  No turning back now!

Every year since I have been here (six years) I have different wildflowers.  My theory is it takes some seeds 5 years to germinate.  It also depend on a lot of variables such as rainfall, temperatures, etc.

Seeds like echinacea purpurea and firewheels, gaillardia pulchella will sprout in the spring of the year they were sown, whether spring or fall.
