Sometimes you are very lucky and come upon a wonderful and exciting new seed or maybe just found it one sale. Many people just save their own seed or are creating a breeding program. However, you will not able to plant the seeds until next year.
You will need to protect your seeds to keep them viable until the proper planting time or when you have enough room. Most of us have put seeds carelessly someplace to keep them out of harms ways, in not the best conditions, only to forget about them until later. Many seeds are quite durable and just like in nature when seeds just drop on the ground until the conditions are right they will germinate. The problem is you will get a reduced germinate rate.
