The whisk fern has passed the cold spring between two branches. I have worried about its survival.
Now this plant is enjoying the gentle sunlight on the chery crotch. I watched it several times and noticed that bark could keep warmer temperature than the ground. The winter temperature in my area can go down to -8℃ or 17°F. Whisk fern cannot grow at this coldness on the ground. This one did choose the good place!
松葉蕨本來是溫暖地帶植物。與地面相比,樹皮能保持溫暖溫度。因此,這個植物能在櫻樹的樹襠上忍受嚴寒。
