I had some guesses but nobody knew for sure what they were.
I was advised to plant them to see what came up and that seemed quite
reasonable, so I planted several of them and marked them with sticks.
None of them came up. But, when I found another one last spring, I
planted it, too and, this time, there was success.
You can see the little stick I stuck in the ground where I planted it.
Come to find out, it is a gladiola bulb.
Now that I see what came up, I'm not really surprised because each year I
find more and more of these beauties in different parts of the garden. I gather
them in one place as I find them, and this one will join them.
