Lygodium japonicum

My Lygodium japonicum often looks a bit tatty with all its leaves turning brown, so I assumed it was effectively deciduous and would regrow from the ground each year. It has been my habit to cut the plant right back to the ground each spring. This year, the bottom half of the leaves have died back but the top half of the plant is still green, if a little “battle-weary”. I noticed that there are a few small “shoots” starting off on the “old” wood. The one in the picture is right at the top of the plant. The plant is also putting up fronds from the ground. We had a relatively mild winter this year for the plants with the coldest tempreature I recorded being -4C
