White teasel flowers - what a surprise!
I thought my seeds came from the plants in my Rosemont garden, but those had pale lavender flowers. Now I'll never know where these came from. That's okay. I like an element of randomness in the garden. I play a kind of seed planting roulette, broadcasting here and there with the knowledge seeds will grown where conditions are right for them. I may have found these on a roadside two years ago and forgotten. Or they may be a gift of the birds. Another garden mystery. This link shows the plants in late June.
