I live in Minnesota. I planted some columbine this year for the first time. The plants are starting to dry up. Are they supposed to this time of year?
My plants always did that half-way through the summer, but they came back the next year. (In my zone, they are a short lifespan perennial usually surviving 3 years or so. After that its best to start over, but that is easy since they reseed themselves.)
Best of Luck,
