Flaming Nettle

Love the colour of these.
I am amazed that you are able to keep them going for so long.
We live at Latitude 51.68 and yet I still struggle to keep them over winter without going leggy. Yours look lovely, how do you do it?

I cut them way back twice a summer and do little cut backs in winter. It doesn't need to grow in winter so I just remove the leggy growths. More attractive if kept under control. I'm always making more, each plant looks good for about 3 years before they get too woody. Medium light, they need a window in winter. This one will move in to replace on thats too out of control.
