Q.life span of a buttercup plant
I have had a couple of these plants for 3 years. The first 2 yrs., they grew beautifully. This year, not so much. The main stems just died off and little runners off of the main one were left. They still get flowers but are no where near what they were. What kind of a life span do these plants have? They get professionally fertilized. Thank you in advance.
I have known of a patch that was over 20 years old! This is rare, and they will, typically live from 4 to 12 years, but with the proper care, you can get them to live for a very long time.
