The shelf life of seeds offered by Clear Creek Seeds can vary depending on the specific type of seed and how they are stored. Generally, most seeds last at least one to two years when kept in a cool, dry environment away from direct sunlight. Some seeds, such as those from vegetables and annual plants, may have shorter lifespans, while others, like certain perennials and grains, can remain viable for five years or longer if stored properly. It is important to check for specific information pertaining to each seed variety, as some may have unique shelf life considerations. Users often find it helpful to refer to the product packaging or the website for detailed guidelines on seed storage and viability. Proper storage methods, such as placing seeds in airtight containers, can also significantly extend their lifespan and ensure successful germination in the future.
