Answer: If the seeds were healthy enough to germinate, they will grow into healthy plants. The problem with old seed is that the embryo inside may not be viable. As long as the embryo remains alive, the seed will germinate. You can help prolong life and viability by properly storing your seeds in an airtight container in a cool, dark location. Some seeds remain viable for longer periods of time than others, but with proper storage, seeds won't age as quickly. This is true of all seeds, whether flower, vegetable, tree or shrub.
