At first glance they look like garlic cloves, but they’re actually about the size of a pea. They’re “bulbils” or the little cloves that form in the flower pod if you don’t snap the scape off of your garlic.
I’ve been doing a little work in our garlic patch to try to figure out how garlic works, and it has led me to leave a handful of scapes on some of our garlic to see what happens. This mostly stemmed from reading that garlic is almost sterile.
When we plant garlic, we take a bulb and divide up the cloves and individually plant them to make new bulbs. Essentially it’s a clone of the parent plant and carries all of its goodness, but also all of its shortcomings. In our case one of the shortcomings is a pest called a bulb and stem nematode. Every year it hitches a ride on a clove into the new garlic patch and spreads. It doesn’t make the garlic inedible, but the odd bulb is rotten when we harvest.

When offspring comes from the parent without using seeds, it’s called asexual reproduction. Potatoes, apple trees (cuttings), grape vines are all reproduced this way. You can continue a good trait by doing this, like the wonderfully sweet Concord grape, but the one negative is that it’s still technically the same plant as it’s parent, so there’s little room for the genetic improvement that comes with a new generation. Bugs and disease learn to like it, and it can’t learn to repel them.
So I’m going to see if our garlic is actually capable of producing true seed. An ability that’s been nearly lost over the centuries.
If you have chives in your garden and let them flower, each flower is actually made up of hundreds of tiny flowers with each one eventually making a seed. Garlic on the other hand, in some cases, has less than a dozen flowers. They’re being choked out by bulbils. I’m speculating, but bulbils don’t seem too natural up in the flower. In some of our varieties, there is a second bulb full of them, just above the ground on the stem. Weird.
