It has been even more satisfying to grow those seeds into a plant that has blossomed and produced more seeds. As I harvested seeds and replanted them, I hardly dared believe that they would germinate. It seems naff to call such a gentle process as germination exhilarating, but the success of my second generation seedlings has me on a high.
Many times a gardener is actually annoyed when a plant goes to seed. Bolting lettuce means that the leaves turn bitter as their goodness (and sweetness) is diverted to seed making. Producing seed is the plant's ultimate goal, and we gardeners often try to prolong the life of many of our plants by dead heading them to stop this process and channel the plant's life force back to blossom or root storage.
Around this time last year, I inadvertently bought and planted heirloom broccoli seeds. At the time I didn't know what "heirloom" meant. During my Saturday morning classes, last year, I learned that heirlooms were a good thing. If you saved the seeds from an heirloom plant they tended to grow plants very true to the type of the parent plants as opposed to hybrid seeds, most often used in agriculture, and which do not produce offspring true to the characteristics of the plant they came from. So in summary - Heirloom = good seeds, non-heirloom or hybrid = not so good seeds.
If a seed is a heirloom seed, it will have heirloom written on the packet.
So, back to the broccoli; I started with twelve seeds and they all germinated. They grew really well and produced very tasty broccoli right through from about last January. The plants grew huge - nearly 7 feet high when I finally cut them down last week.
During the summer, we had to spend a few weeks in Hong Kong, and by the time we got home many of the non-harvested broccoli florets had begun to blossom.
Seed pods formed slowly but surely. It required patience and the ability to turn a blind eye to an unkempt look to this part of the garden. But eventually there seemed to be seeds in the knobbly pods.
As are many of the seeds that plants produce. Here are some arugula seed pods.
So, I also had bunching onions in my garden which I had gotten as seedlings. They flowered with big white showy blossoms.
Likewise, my sweetpea blossomed gloriously in the early summer, and I allowed a couple of plants to go to seed, even though these are not heirloom either.
Some basic rules about seed saving and germination
- Try to let the seeds ripen as fully as possible before you harvest them.
- If you find insects on your seed pods throw them out or use diatomaceous earth to destroy the critters. They'll eat your seeds if you don't, and possibly spread to the entire crop.
- Keep the seeds cool and very dry - use little silica packets (like the ones you get with new shoes) to help absorb water whilst storing them. This is a good use for your old jam jars - remember to label them with the year they were collected.
- Seeds will be viable from about 3-5 years. You can test a sample for germination by putting them on damp kitchen roll to see what percentage germinate.
- Germination requires - warmth, oxygen and water. Very few plants require light (e.g. chamomile) to germinate. Most are not affected by light and a few are prevented from germinating if there is light present.
And just look at those broccoli grow:
That's the beauty of seed saving (especially heirlooms) - it saves you having to buy seeds every season and it means that the big seed companies and the government aren't the only ones with seeds.
In addition to this using heirloom seeds perserved genetic diversity amongst the vegetables and tend to taste better. Heirlooms are typically better adapted to growing where they having been growing for some time and are thus more disease resistant, tolerate local weather conditions and repel local pests better.
It makes me feel weirdly attached to these little "children" of the plants that I grew. It's great to see them growing happily in my garden, and I can't wait to eat 'em
