expiration of packaged zinnea seeds
Garden seeds do expire, but in a different way then food products. After a while they just rot, or won't grow. Usually on seed packets it gives you a best if used by date, which is usually equivilent to one or two years
AT some point, yes, seeds stop becoming as viable. This can vary from plant species to plant species. You will know if they are no longer good becasue they won't sprout. If they are wildflowers, then planting them usually just involves scattering the seeds in a nice location. I would go ahead and try to grow them. You never know, there still may be some viable seeds in there.

Yes but not totally. If you look on the label it will tell the year the seeds were packaged and the percent of germination. Each year that viable percentage goes down. You can compensate for older seeds by throwing in more of them than you would for fresher seeds. In a home garden that will work. On a farm where labor cost is a bigger factor it is not as sensible an idea.
