Florabank Guideline 3 - Improving on basic native seed storage
In general, we store seed to maintain it in a viable condition from the time of collection until the time of sowing. Storage time varies according to the purpose for which you store the seed. The longer you need to store it, the more expensive it becomes. Careful storage may help alleviate problems of seed availability and large seed crops may be used for several years of revegetation activity, avoiding the need to rely on the current crop alone.
