Several packets, including zinnia, marigold, aster, dianthus, cornflower.
Packed for 2002, unfortunately couldn't plant, still worth a gamble this
year if the odds they're still alive are better than 50-50. What
percentage
of each should I expect to germinate after 1 year of storage at cool room
temperature?



I'm using 2001 zinnia seed and 1999 marigold seed. I note a slight loss
of vigor in the zinnia (down to about 80%), but I've used marigold seed
as old as 6 years with good (70%) results.

Annual asters don't store well for me. I buy new seed every year.

Don't have experience with old dianthus or cornflower seed.

Most other stuff will last a year. Many seeds will last more.

Pelleted seed is sometimes primed: i.e. the seed is pre-germinated so
that germination occurs more uniformly after planting. In this
condition, the seed will not last as long, so don't count on saving it
for next year. You are unlikely to run across pelleted seed in the seed
packets in the racks.
