Seeds of Change

This is, quite possibly, my favorite time of year.  Now that most things are finished growing (including the weeds), most of the harvest has taken place except for my tomato plants (which seem to have some delusion of immortality this year and persist in staying green on the vine for weeks), and life settles down into the dull roar of trying to get the farm ready for winter.  But there is one job left to be done....picking out and saving next year's garden.

As a kid,  I always thought that seeds needed to be purchased every year.  It was just what we did each spring - looked at the seed catalog and either ordered them or picked them up at the local do-it-yourself store, and while this always seemed to work, it never dawned on me that nature does a pretty good job of doing this for herself.

Almost everything in the garden produces a seed of one type or another that contains within it all the genetic information to pass on to the next generation of seeds.  Amazingly packaged into a tiny capsule that will often survive through a harsh winter and burst forth in the spring with no more than a little coaxing from sun and rain.  What astounds me even more is how, over the course of the last eight years, I have watched many of the species of plants that I like to grow, adapt themselves to this environment and take hold.  Nature's ability to adapt and survive amazes me.  Take the Impatient for example:  Most of these brightly colored, shade loving flowers are hybrids that originated in Africa - and it is a lot warmer in Africa than it is here so they are not expected to survive even a light frost - and yet, I have found that a few of my Impatient plants that I planted two years ago formed seeds that were able to reproduce viable plants and, what's more, they can now overwinter in an Iowa winter. 

My marigolds have literally taken over the gardens and though I curse them in the spring when they appear everywhere, I am happy to have them around at this time of year because they are hardy and can stand up to these chilly nights.  I used to collect these seeds, but now I just let them seed themselves and then I move them in the spring to the places that I want them.

Finding the seeds of any plant is typically not to difficult.  Peas and beans are easy, but I always chuckle in the spring when we are planting them and one of my kids stops and peers at the seed in their hands and says, "Hey mom, these look just like the peas we eat."  The most difficult thing I have found with peas and beans is the importance of not eating all of them - some have to be saved back for seed and usually it is best to pick the nicest looking of the plants to save.

Lettuce can be a bit more difficult to determine what is the seed, but that is only because we don't allow the lettuce plant to typically live out its entire life cycle - we eat it in its young and tender teenage stage.  After it gets too bitter to eat and starts to bolt, it will then form a weird looking flower and then those start to go to seed - save those and you will have lettuce seeds for next year.

Sometimes figuring out where the seed is on a flower takes a little time and observation.  So many gardeners will tell you to "dead head" things that are no longer blooming, which is fine but then you often miss out on the seeds.  Personally, I think this is a bit of marketing on the part of the nurseries that grow flowers - they would rather people didn't get their own seeds because then it cuts in on their business so they tell us to do things like remove spent flowers.  Yes, it makes your flowers look prettier, but then they don't reproduce, and there are several plants that have fairly interesting looking seed pods that you would otherwise miss if you cut them off as instructed.

 There are many horticulturists that will tell you that many of the flowers we buy, or seeds we buy are hybrids and will not produce "true" seeds, and this is entirely true.....the first few years.  But, what I have discovered, often through benign neglect, is that flowers and plants, if given half a chance, will revert back to a more natural variety that does produce seeds true to form.  I am often reminded of the line in Jurassic Park when Malcolm says to the scientists, "Life finds a way" and he is entirely correct.

So, I meander around the garden and pick a handful or two of seeds off of the flowers, or I cut open the nicest looking tomato and, before throwing it in the pot, I scoop out a few hundred seeds for next year.  Some of the plants I simply watch ripen and dry and then shake the seeds out where I want them next year and others I simply let fall and plan on moving them to a new location after they sprout. 



A seed is both a plant's last and final hurrah before being annihilated by winter, and it's boundless hope for the future.  It will have absolutely no knowledge of whether or not what it produced will ever come to fruition, but it produces them just the same.  And I collect them.  I am the bridge to the future for many plants - keeping them warm and dry through the cold winter months and them scattering them in the spring to start over.  And they, in their turn, take care of me and provide me with a bridge to my future in the form of food. 

There have been times, when stuck indoors studying for genetics tests, when I have wondered how Gregor Mendel, the Austrian Monk that established the basics for genetics, could have spent countless days and seasons watching pea plants.....now I understand.
