Are Echinaceas perennial?
Hi - I was just wondering if anyone knows whether Echinaceas are biennial or perennial in the UK? I have read that they are both, and an internet search seems to imply that it depends on where you are. I am in Lincolnshire. I planted some last year and cut out all of the flowering stems before they had a chance to develop in the hope that that would make them stronger for the future. Then I found out that they only lived two years and I wished I had let them flower! I am planting some more this year, but if they are only biennial, I may well let these ones flower in the first year. Thanks for your help.
