Seed Saving for More Garden Blooms, a great way to expand your garden for free. And you can join a seed swap to get different ones.
It is the time of year when many of my garden favorites are going to seed. I often collect seeds to give away or replant in different areas. Seed saving is a great way to expand your garden with plants that have done well for you already, have some extras to trade for seeds of plants you have yet to try and give as gifts to gardening friends.
Though the seed heads lack the flamboyance of the flowers they do have a beauty all their own.
Mostly that beauty is knowing these little spiky things will produce beautiful flowers next Spring and Summer and they provide food for critters during the cold months of winter.
Note: There are many hybrids that set seeds but are sterile and will not grow from seed. I mention this is my Echinacea post. Also your flowers will cross pollinate and you will not always get the same colors from seeds saved of a particular flower. The only way to get a plant exactly the same to clone it from cuttings, root division and or layering.
I can let these fall to the ground to reseed themselves but if I want to grow some in a different area, plant them at a later time or give some seeds away I need to collect them before they fall. (the flowers produce tons of seeds, you will have plenty to keep and to give away).
With the Cosmos I just clip off the seed head into an easy to hold container like a clean, recycled plastic sour cream tub.
Most of the flower seeds I collect the same way. I do let them ripen first. Green seeds are worthless. This Sweet Pea pod is still too green.
But give it another week or so in warm weather and you are ready to clip it off into your tub. See how these are a bit browner than the photo before, these are ripe enough to collect. If I would’ve waited they could’ve popped open and scattered the seeds on the ground.
I will leave them in the tub with a loose top on it, a coffee filter will work, it will let air come in and moisture out. The tub needs a lid because when the pods pop open as they continue to dry the seeds will spring out everywhere and not stay in the tub. I don’t need Sweet Peas coming up in my greenhouse floor. Once the pods have opened I will remove the shells, the seeds will have joined their compadres on the bottom of the tub. Click here for a post on How to Grow Sweet Peas
Delphiniums ripen as they have bloomed, from the bottom to the top. The seed heads on the bottom will be ripe while the top ones are still green.
I usually just clip off the ones ready and wait to collect more but I also tried this method which I saw on a t.v. show. I placed a large brown grocery bag over the stalks and bent it over and shook it to release the seeds that were ripe, I did collect the seeds faster than clipping but one stem snapped so I don’t know if I recommend it but I did make the mistake of trying to bend it over the support frame that kept it upright. Maybe if it had not been there it would’ve worked better.
Gaillardia seed heads are super prickly and will stab your fingers like a cactus so be sure to wear gloves to collect their seeds. I just use my pruners as shown in my How To Deadhead post and let the seed heads fall into my plastic tub.
Hollyhock seeds ripen like the Delphiniums, bottom to top. You can even still have some flowers on top of the stalk as you collect the ripe seeds lower down. Wait until the paper casing is dried and opening up, that is when the seeds are ready.
Before I collect the seeds I get some envelopes that would normally get tossed as I pay or deal with much online and mark them with the names of the plants. Nothing fancy but it works.
Want something a bit fancier Click on these posts for some cute seed envelope printables, they make it even more fun to give the seeds away!

Now time to separate the seeds from the chaff. I pour the contents of the sour cream tub onto a paper towel. Most of the time the seeds are heavier than the chaff and fall to the bottom of the pile.
These Larkspur seeds are a good example. I pick up the stems and shake them a bit more to get more seeds to come out of their casings and then pick out the little casing pieces to leave mostly just seeds. I then toss the casings into a bucket headed for the compost heap, fold the paper towel carefully in half and pour the seeds into the proper envelope.
Shasta Daisies (all kinds, Silver Princess, Crazy Daisy, etc)
The paper of the envelopes let any moisture escape that could cause fungus to grow on the seeds, I have a metal box I keep them in but I don’t put the lid on it, some use a shoe box which is great too. I have my box in my greenhouse which is probably not the best over all place since it has such temperature swings but it works for me. Usually it is recommended you keep seeds in a cool, dry place.
I don’t collect all the seeds, that would just be overkill as there are millions. But I leave many of these perennials and biennials to overwinter in place. It provides needed food for birds and other wildlife.
True it does not look neat and tidy as many prefer but I love seeing birds landing on top of the daisy, echinacea and or black eyed susan seed heads to snack on, especially when there is snow on the ground and it is tough for the birds to find other food sources.
Rose Campion (Lychnis Coronaria)
If I need to dig up any of them to make room for something different or to thin them I pile them up nearby, it may not look attractive but you should see the wildlife that make this a refreshment stop or winter haven before heavy snows bury it deeply. Right now the Junco’s flock to my piles to pick at the seeds each morning.
I am clearing out some spaces to put in different plants, many that I have never grown before and I have a few of these discard piles growing.
Closer to winter I will pour a few buckets of chicken litter on top so they will compost in place just fine.
And this below is a new nursery bed. It is where I will start seeds this fall of flowers that will overwinter just fine then come Spring I will plant them in different places. Right now it has been cleared and I am watering it to encourage the weed seeds to sprout, I will yank them out and then when it is time for me to plant the seeds there will not be many weed seeds left to germinate and compete with my flower seedlings.
As you can see there is several things sprouting that I do not want here, so I will take my shovel and hoe dag and clear this again, water and do it over. Click on over to this post to get a list of my favorite garden tools
