How To Save Bachelor S Button Seeds For Planting Gardener S Path

Also known as cornflowers, bright blue, pink, purple, or white Centaurea cyanus flowers are among the first to bloom in spring if you plant them right before the first frost. A draw for pollinators, they have edible blooms, and flower for months after that spring start. Since there’s so much to love about these members of the Asteraceae family, I always want more of them. I’ve found the most cost effective, low-labor way to reach that goal is to save the seeds at the end of the season. We link to vendors to help you find relevant products.

Take Action When They Form Seeds

According to the wildlife experts at National Geographic, cornflowers are one of the top 10 flowering plants to attract songbirds.

While that’s a great reason to plant them, it also means you might have to compete with the birds a bit for next year’s supply. This year, I left plenty of blue bachelor’s button blooms on plants I grew in a tiered raised bed. But when I went to collect the pods, I noticed that more than half of them had been stripped of their seeds. The likely culprit? Probably the cardinals that I love so dearly.

They reside in my winter honeysuckle hedge and plunder my garden for water from baby tomatoes, and seeds from any manner of perennial and annual flowers. Happily, cornflowers produce loads of blooms starting in late spring and going right up to the end of the summer. So I’ll still have plenty of chances to get a stash of ‘Blue Boys’ to plant next year. But to avoid allowing the birds to eat the whole lot, I do advise taking note when the flowers begin producing seeds. Once the petals start to fade to brown from their original white, blue, or purple, the seeds start to form within the base of each flower. If you’ve noticed that a lot of the dead blooms are now merely chaff and a dry stalks, you may want to cover a few of the remaining blooms that are forming seeds with a bit of bird netting until you get a chance to harvest.

Harvesting

While it’s a great idea to deadhead to keep these plants producing those bright blooms all season long, the dry, withered flowers are also the source of next year’s plantings.

So be sure to leave a few of the fallen soldiers on the stalks long enough that you’ll have something to collect. To get the best of both worlds – providing sustenance for the birds while still being able to collect seeds for next year – focus on saving towards the end of the season. Once you stop deadheading, the dry stalks will complete the majority of the process on their own. All you need to do is pluck the faded, completely dry flowers from the stalks. If you prefer not to wait for the spent buds to dry to a crisp in the garden, you can cut the stalks when the flowers die and then hang them upside down in a cool, dry place. In either scenario, wait until the dead flowers are completely dry at the base of the flower heads. Then set one in the palm of your hand and use a finger from your other hand to rub it open and release the seeds from the chaff. They’ll still have little tufts of fluff on the top of each, and the bottoms will be black. It’s okay if you get a bit of chaff in the mix. It will just go in the ground with the seeds, no harm done.

Storing

To be on the safe side, let those little tufts dry on a tray or screen in a cool, dry spot for a couple of days after separating them from the chaff. I use the mantel in my living room, but any location without vermin, excessive heat, or humidity will be fine. Then store them in an airtight container. Keep it away from humidity in a place with cool, but not cold, temperatures.

Spread the Bachelor’s Button Cheer

It’s so nice to have extra seeds on hand, enough to share and maybe even plant in a few more areas than you usually would.

But if anything goes wrong with the process, like it did for me with those snacking cardinals, rest assured – there are plenty of reputable places to purchase seeds for these cheery blooms.
