Believe it or not, this butterfly weed is now 15 years old. I spotted it growing in an undeveloped lot across the street from my house the summer we moved in. Since we were the new folks on the street, I snuck back in the evening to "steal" it and plant it in my garden, where it immediately died. To my surprinse, the following spring it came back and has give me many years of pleasure. It has hosted many generations of monarch catterpillars as well as every bee in the kingdom. Yes, I'm sure it's the same plant, growing in the same spot.
What are you "garden granddaddies"?
