Radiocarbon dating confirmed that the seeds were 32,000 years old.
Will seeds from 2015 germinate?
Yes. Plants grown from expired seed packets will grow to produce healthy and fruitful harvests, just as their younger counterparts.
Will 20 year old tomato seeds grow?
Yes! If tomato seeds are appropriately fermented, dried, and stored, they can last up to 10 years with a germination rate of 50%. If used within 4-7 years, the germination rate will be even better. Heirloom tomato pioneer Carolyn Male has re-awakened 22-year-old tomato seeds.
Will 20 year old seeds grow?
Yes! Even seeds that are thousands of years old can germinate. But proper pre-treatment is essential, and the older the seed, the less energy it has left in storage. Seeds from annual plants aren’t often designed to last many years, part of what makes the germination process so tricky.
Do heirloom tomatoes grow true to seed?
Seeds from an open-pollinated variety produce offspring that are identical to the parent plant. As long as cross-pollination can be prevented, seeds that are saved will produce identical tomatoes year after year. Seed saved from a hybrid tomato plant or from cross-pollinated plants will not generally grow true to type.
Why are heirloom tomatoes so expensive?
Why are Heirloom Tomatoes So Expensive? Heirloom tomatoes are expensive because they are not mass-produced. With fewer available (than hybrids), their price typically stays high. Heirlooms are not disease resistant, their vines produce less per acre than hybrid varieties, and they do not travel well.

Can seeds last 100 years?
It is known that seeds of good quality can stay alive for several decades and even for centuries.
Can a seed grow into a plant after many years?
Age — All seeds are viable for at least a year, with many others viable for definitely two years. After that, the seeds germination rate may start to drop off. It’s not to say that these are not viable seeds that won’t grow into healthy plants.
How long will a seed last in storage?
To keep the seeds cool (ideally, below 50 degrees), some people store them in a jar in their refrigerator or freezer. Seeds in good condition and stored properly will last at least one year and, depending on the plant, may last two to five years.
Can you plant 2 year old seeds?
Age – All seeds stay viable for at least a year and most will be viable for two years. After the first year, the germination rates for out-of-date seeds will start to fall. Type – The type of seed can affect how long a seed stays viable.
How many years can you keep tomato seeds?
dry, store them in an airtight container. If you keep them dry, tomato seeds should last at least five years. If they are dry and cool (in airtight jars in the basement, garage, etc), they can keep for 10 to 12 years.
