I’m in zone 10 (San Diego, CA) and my echinacea plant was done blooming in late fall. From what I read I was supposed to cut the plant down to ground level so I did (eek!) with the faith that it would grow back. The small but of stem that was exposed turned brown and dried out. I pulled at it today and it just gave way. I moved the soil back to inspect the roots and I see bright purple which I’m assuming means it’s still healthy and alive down there. Is this just the natural winter process ? Will the plant start growing again this year? It was so big and beautiful so it’s hard for me to imagine it getting to that stage from where it’s at now. Any wisdom ? Thank you !
