Yes, old flower seeds have the potential to grow, but their germination rate may decrease over time. It is recommended to store seeds in cool and dry conditions to maintain their viability.
More comprehensive response question
Old flower seeds have the potential to grow, although their germination rate may decrease over time. It is important to store seeds properly to maintain their viability. As gardening enthusiasts, we often encounter situations where we come across forgotten or leftover seed packets from previous years. The question then arises: “Will these old flower seeds still have the ability to sprout and flourish?” Thankfully, the answer is generally positive.
If stored correctly, flower seeds can remain viable for a certain period of time, and their age doesn’t necessarily render them useless. However, it is important to note that the germination rate of old seeds may decrease, which can lead to lower success rates in terms of seedling establishment. The viability of flower seeds greatly depends on several factors such as the type of flower, seed quality, and storage conditions.
According to the renowned American horticulturist Liberty Hyde Bailey, “Old gardeners never die; they just very slowly turn into the most magnificent flower.” Similarly, old flower seeds can still hold the potential to beautify our gardens with their blossoms. Here are some interesting facts on the topic:
-
Viability can vary: Different flower species have varying longevity when it comes to seed viability. While some seeds may only remain viable for a year or two, others can retain their viability for much longer periods. For example, Zinnias and Marigolds have relatively shorter viability, whereas seeds of plants like Cosmos or Sunflowers can remain viable for several years if stored properly.
-
Factors affecting seed longevity: The viability of flower seeds can be influenced by several factors, including genetics, seed moisture content, storage temperature, and oxygen levels. Seeds that have been well-preserved and protected from moisture and extreme temperature fluctuations have a higher chance of remaining viable for extended periods.
-
Proper seed storage: Storing old flower seeds correctly is crucial for maintaining their viability. It is recommended to keep seeds in a cool, dry, and dark place. Many gardeners choose to store their seeds in airtight containers or envelopes, placing them in a refrigerator or freezer to provide optimal conditions for preservation. Always ensure that the seeds are completely dry before storing them to prevent mold or fungal growth.
To illustrate the viability of flower seeds over time, we can look at the potential germination rates of old seeds. The table below demonstrates hypothetical germination rates for flower seeds of different ages, showcasing the potential decline in viability:
| Seed Age | Germination Rate |
|---|---|
| Fresh | 90-100% |
| 1 year | 80-90% |
| 2 years | 70-80% |
| 3 years | 60-70% |
| 4 years | 50-60% |
| 5+ years | Below 50% |
It’s important to note that these percentages are approximate and can vary depending on various factors. However, they provide a general understanding of how germination rates may decrease as seeds age.
In conclusion, while the germination rate of old flower seeds may decline over time, they still possess the potential to sprout and grow when provided with suitable growing conditions. Storing seeds properly in cool and dry conditions can greatly enhance their viability, giving us the opportunity to witness the beauty of these old seeds transform into magnificent flowers. So, don’t be afraid to give those forgotten seed packets a chance and let nature’s magic unfold in your garden.
See the answer to “will old flower seeds grow?” in this video
In this YouTube video about seed viability, the host explains a method for testing the viability of old seeds before purchasing new ones. By using kitchen towel as a growing medium and keeping it damp, but not soaking wet, gardeners can determine if the seeds are still viable and save time, effort, and money. This method is particularly useful for gardeners with accumulated opened seed packets of unknown age. The host also shares her process of preparing old seeds for germination, using a paper towel, a sealed bag, and labeling for tracking. She mentions that calculating germination rates with 10 seeds can help adjust the amount of seeds to sow. Additionally, the host invites viewers to join a live chat on gardening.
On the Internet, there are additional viewpoints
Some old seeds will stay good and germinate for up to 5 years or longer, while others are only viable for a year or two. On average, old seeds will still sprout for about three to four years after their “packed for” date – especially if they’re stored in ideal conditions.
There is a good chance that those old seed packets will have a high percentage of seeds that will germinate just fine. Most seeds, though not all, will keep for at least three years while maintaining a decent percentage of germination. And even a group of very old seeds may have 10 or 20 percent that still sprouts.
No harm will come from using old seeds. The flowers or fruit that come from out-of-date seeds will be of the same quality as if they were grown from fresh seeds.
Yes. Plants grown from expired seed packets will grow to produce healthy and fruitful harvests, just as their younger counterparts. With this in mind, one may be left to wonder then, when do old seeds expire?
Yes, old seeds may produce less vigorous plants. Seeds that are just a couple years old should still grow to become perfectly robust plants, but as seeds get really old, both the germination rate and plant vigor can decline.
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. With each trip around the sun, energy declines.
After your perennial flowers are established, they will begin blooming and grow larger every year. In a few years’ time, you’ll be able to make even more plants by dividing the ones you have.
People also ask
Do flower seeds get too old to plant?
The reply will be: All seeds will be viable for one to two years. After two or three years, germination rates will drop for many types of seeds and will eventually fall to zero. So, stocking up on seeds for an “emergency” isn’t a good idea because they don’t last forever. Download a free chart that tells you if your seeds are too old.
Beside above, Are old flower seeds still good? Response: Seeds that have been stored in a cool, dry place are generally viable for at least a year past the season for which they were packaged and may be good for up to five years.
Can you plant seeds that are 7 years old?
The answer is: Depending on the type of plant, some seeds can still grow even years after you have ordered them. “Some seeds can store well and stay viable for five, six, seven years,” Garland added. “If they’re stored well in a cool dark location, they can stay viable for very long.”
Secondly, How do you know if flower seeds are still good? Answer: You also want to look at vigor. If your radicals look more wimpy than rad then you may want to start with some fresh seeds. Instead.

Also to know is, Should I plant seeds after 5 years?
Response to this: But I have found that after 5 years I will still get 3 out of 4 seeds to germinate. As a package of seeds gets a little older I will plant a few extra seeds to make up for the fact that some might not grow. But if seeds are under 3 years old then you shouldn’t have any germination issues. You should feel free to plant them normally.
