Advice please on Phlomis italica
My 2 yr old Phlomis italica is looking very sad after the recent cold spells, despite being fairly wrapped up well. I knew it was a tender plant but it had survived it's 1st year and flowered last year - pinkish blooms instead of the usual yellow ones. It is showing signs of life so I've lightly pruned the dead top leaves off. Does anyone else grow this plant and is there anything else I can do to improve its chances?
