Here is another reblogged article from years ago.
Seed that is available in hardware stores and nurseries came from somewhere. Plants just like those that such seed grows into produced it. Someone, or many someones, collected all that seed to make it available to others. Similarly, several plants in our own gardens produce seed. Anyone who is interested in collecting seed to grow more of the same plants could make good use of it.
After bloom, most flowers deteriorate and disappear into the landscape. Some leave behind desirable developing fruits or vegetables. Many of the flashiest flowers are too extensively hybridized to produce seed. Many produce some sort of seed structure that typically gets removed, or ‘deadheaded’. This diverts resources from seed production to subsequent bloom or vegetative growth.
If not removed, such seed structures can mature to produce viable seed. Those who enjoy collecting seed often intentionally leave a few seed structures for that purpose, instead of deadheading completely. For plants with long bloom seasons, this technique should involve the latest blooms. The same applies to vegetables that normally do not mature prior to harvest, like summer squash.
Such seed or fruiting structures, including vegetables, must be completely mature before collecting ripened seed from them.
Sunflower, cosmos, calendula, marigold, campion, morning glory, columbine, hollyhock and snapdragon are some of the easiest flowers for collecting seed from. California poppy, alyssum, phlox, and several other annuals are happy to self sow their seed, although collecting seed from them is not so easy. Nasturtium and honesty (money plant) seed is easy to collect, but self sows as well.
Collecting seed is limited only by practicality. Some plants, particularly hybrids and exotics (which are not native and may lack pollinators), produce no viable seed. Extensively bred varieties are likely to produce progeny that are more similar to the basic species than the parent. Once collected, some seed need special treatment in order to germinate. All seed should be sown in season.
“Edelweiss, edelweiss, every morning you greet me. Small and white, clean and bright, you look happy to meet me. Blossom of snow, may you bloom and grow, bloom and grow forever. Edelweiss, edelweiss, bless my homeland forever.”
Why are there no corny songs like this about California poppy?
Although I never met edelweiss before, I always thought that it must be quite excellent. Those who are familiar with it where it grows wild in European mountains seem to believe so. It does not look like much in pictures, so must be much more impressive if experienced directly.
A colleague here who met it directly in Austria decided to grow some, and easily procured seed online. The seed was chilled in a freezer to simulate winter in the Alps, and sown just prior to the last of the rain as winter ended. They germinated, and the seedlings started to grow, but then mildewed. The potting soil that they were in was likely too rich and too damp.
After all, edelweiss naturally lives in limestone scree, where the climate is harsh. Such environments are less than hospitable to fungal pathogens that cause mildew. Rich and well watered medium that would be considered to be a good situation for so many other seedlings may not be what edelweiss seedlings are comfortable with.
There are already plans to try edelweiss again next year. Seed might get sown in sandier medium, and a bit later in the year, so that they are not so regularly dampened by rain. If they survive beyond their seedling stage, they will likely become more resilient as they get established in an appropriate landscape. There are a few situations here where sandy soil drains well.
Perhaps I will eventually experience edelweiss, and see what all the fuss is about.
It is such a bad habit! Even if I spend no money, I spend too much time perusing what I could spend a little bit of spare cash on. On rare occasion, I actually do spend a little bit on something that I can get a good deal on, not because I actually have any use for it, but merely because I got a good deal on it, . . . or because I believe that I may not be able to find it for sale again later.
Now, I have more than two hundred seed for Pygmy date palm, Phoenix roebelenii. They certainly were inexpensive, costing less than a few dollars. Most of the expense was for postage. It really was a good deal. However, I have no plan for so many Pygmy date palms. I do not expect all to germinate; but I have no plan for just half of them. Actually, I have no plan for just one.
The other seed to the right in the picture are for muscadine and scuppernong, Vitis rotundifolia. Although I purchased them as a ‘mix’, the seller kindly separated the two varieties. They are easier to accommodate than two hundred palms, and I really do have plans for them. I know growing them from seed is riskier than growing known cultivars, but I wanted them to be ‘wild’.
Regardless, I really should not have purchased even muscadine and scuppernong seed while there is so much other seed here that can not be accommodated. I really must sow all of the old seed this autumn or winter, whether I have plans for it or not. I suspect that most will not germinate. Some of the most questionable seed can be sown out in the garden rather than in flats.
No more eBay!
By now, I can safely assume that any of the various old seed that were sown late last February that have not yet germinated are not likely to do so. They were all so old that I knew at the time that their viability was questionable. Nonetheless, I could not discard them without confirming that they were no longer viable. Four months later, this empty flat just about confirms it.
So far, the sole survivor is a seedling of a California fan palm, Washingtonia filifera. It looks silly all alone in the otherwise empty flat. Yet, even if no other seedlings germinate, the effort will have been worth this dinky palm seedling. California fan palm happens to be my favorite palm; but I would have been just as pleased with something that is not a favorite.
This little seedling is still too young to be pulled and canned. It will therefore wait and grow in the flat for now, and perhaps until autumn. I still hope that other seed will germinate during that time. Even if they do not, the empty flat will get set aside where it will continue to be irrigated as needed until late next spring. Viable but old seed may be unusually slow to germinate.
I can not help but wonder if some of the seed did not get enough chill after they were sown late in February. Maple, ash, elm, birch and arborvitae might require more of a chill through more of winter to be convinced that the warm weather afterward really is spring. I am not quite ready to give up on them yet.
There are still many more very old seed to sow this autumn. For most, I do not expect germination to be any better than it was for this previous batch.
It is not easy to discard seedlings and cuttings that have potential. We are supposed to sow several seed for vegetable plants where we ultimately want only a few, which typically produces a few extra. Feral seedlings for other types of plants commonly appear in the garden. I happened to grow a few seed that were marginally old, but that I did not want to discard. Nor do I want to discard deteriorating but lingering cool season annuals from last winter.
1. Since no new warm season bedding plants are going into the landscapes, cool season bedding plants are lingering until they succumb to the warmth. This pansy is not ready to give up yet.
2. ‘Roma’ tomato seedlings that got plucked to favor stronger seedlings got plugged in cells for later. They got sown very late, and plugged even later, but might become a nice second phase.
3. Extra summer squash seedling were also too good to discard. The main plants are producing now. This one should find a home quick. Since it can produce all season, no phasing is needed.
4. Ponderosa pines make extras too. This seedling got plucked along with other weeds, but was too exemplary to discard. (For the record, someone else salvaged it; so I can not be blamed.)
5. This is too blurry and dinky to look like much, but is a seedling of California fan palm. The seed was so old that I doubted its viability. I am very pleased with it, even if is the only survivor.
6. White California poppies are rare in nature. This one was left in the landscape while many of the orange poppies were removed along with weeds. There is another only a few yards away.

This was not planned very well. Actually, it was not planned at all. While sorting through the seed for a vegetable garden, I found a can of seed for winter squash that was a few years old. They might be close to five years old. I really do not remember. I did not expect them to be viable, but did not want to discard them without at least trying to test them for viability.
Rather than just put them in damp rag for a few days, I plugged a few seed into a spider plant on a windowsill, and forgot about them. I really did not expect to see them again. When the first one emerged, I though it was a weed, so plucked it out. When I realized what it was, and that it came out intact, I felt badly for it, and like the original seed, could not discard it.
I do not remember why, but at the time, I did not want to go out to can it in a real pot. Nor did I want to plug it into the garden while I was still getting other seed situated. I therefore planted into an empty eggshell from those drying for coffee. I scraped a bit of medium from a potted bromeliad. It was happy on the windowsill for maybe a few weeks.
The other seed germinated too, but were more carefully removed and plugged into the garden. Since the seed was still viable, I sowed more around the junipers outside. Somehow, in the process, I neglected to put the little seedling in the eggshell out into the garden with them. It has not been happy in here, so has not grown much at all.
Now that the winter squash are already growing well outside, and the summer squash are already producing, this unfortunate seedling still needs to go out to join them.
If I were to grow seedlings inside again, I would do so in some of the cell packs that we recycle from work. They are more efficient, less wobbly, and they do not look so ridiculous.
Many of us who are still sowing spring seed know the doubt. Seed for warm season vegetables and bedding plants is presently scarce. Consequently, we doubt that all the varieties that we want are still available. Many unusual varieties that we purchase by mail order or online are sold out. Some more popular and reliably obtainable varieties in supermarket seed racks are going fast too.
Home gardening is very suddenly more popular than it had been for a very long time. Those who can not work at their respective professions have much more time to work in their gardens. Many want to grow a bit more produce at home, in order to shop amongst others in supermarkets less frequently. Many who have never enjoyed gardening before are now taking a serious interest in it.
This adds a few more complications to planning the garden. Choices really are limited. Some of us must be satisfied with what we get. Instead of trying new and unusual varieties, we might need to try old and common varieties. It might be a new and unusual experience, and an interesting way to learn why they have been so popular for so long. This applies to young plants as well as seed.
Although more varieties are available online and by mail order, it is now more important to purchase them early. Delivery is not as prompt as it was prior to this increase in popularity of gardening. Seed providers are overwhelmed by the demand. Since it is already late in the season, it is probably too late to order seed that start in spring. It is not too early to start procuring seed for autumn.
It is also a good time to share surplus with friends and neighbors who may be experiencing the same scarcity of seed and seedlings. Although it is too late to wait for delayed delivery of seed that gets sown in spring, it is not too late to sow some types if they are already available. If left outside to avoid personal interaction with recipients, seed might need protection from rodents and birds.
Anyone who is experienced with gardening knows that it involves challenges. This is certainly a new one.
Money plant, Lunaria annua, which some may know as ‘honesty’, is honestly not a wildflower here. It is neither native nor naturalized. Yet, it seems to grow wild on roadsides, in drainage ditches, and around the perimeters of some of the landscapes. It certainly produces enough seed to naturalize. It just would not have done so in this climate without a bit of intervention.
Many years ago, someone who maintained the landscapes here started sowing seed for money plant. I do not know if he was the first to sow the seed, or if he collected it from plants that someone else grew. He collected seed annually to disperse randomly by simply tossing it out wherever he though it might happily grow into more money plant.
Since money plant wants a bit more water than it gets from annual rainfall here, it was happiest where it is most often seen now, in roadside drainage ditches and on the perimeters of irrigated landscapes. It somehow competes effectively with other seemingly more aggressive vegetation. In the more favorable situations, it self sows, but can not perpetuate indefinitely.
The horticulturist who dispersed the seed for so many years retired a few years ago. Consequently, there has been a bit less money plant annually since then. It certainly tries to naturalize, but was rather scarce last year.
We could not allow it to go extinct just yet. We collected some of the seed from the plants that bloomed last year. I dispersed a few where I thought they would be happy without being obtrusive in the landscapes. I gave most of the seed to a neighbor who happens to enjoy tossing random seed into random (but hopefully suitable) spots where wildflowers would be nice.
It is such a delightful tradition that is worth continuing.
31,800 years or so ago, busy arctic squirrels of northeastern Siberia stored more campion seed than they could consume. Of a store of more than 600,000 such seed, which were found deep below permafrost, three immature seed contained viable embryos. These three embryos were extracted and grown into plants that bloomed and produced new seed as they would have 31,800 years ago.
A 2,000 year old date palm seed, which was found in the palace of Herod the Great on Masada in Israel, is the oldest known intact and mature seed to germinate. It was approximately 29,800 years younger than the miraculously viable embryos of the Siberian squirrel stashed campion seed, but is ridiculously older than the oldest of the old seed in my partly neglected collection. There is hope.
Some of the seed that I saved is not dated because, at the time, I figured that they would be sown during the following season. A few of those that are dated are embarrassingly from five years ago. I know that canna seed lasts much longer than that. So do seed of some of the most aggressively invasive exotic species, such as broom and Acacia dealbata. Vegetable seed are not so fortunate.
However, I cannot discard them without giving them a chance. If they do not germinate on schedule, replacements will be sown immediately.
The two cans of seed to the left in the picture above are for two unknown varieties of pumpkin, and might have been three years old last autumn. Butternut squash seed to the upper middle is about the same age. Hyacinth bean seed to the lower middle is perhaps a year older. Blue dawn flower seed to the upper right is at least five year old. Parsley seed to the lower right was packed for 2015.
