This small little plant

Notice a little "grass" at a "cave" beside the signal light, though of removing it but then only to realise...is a plant, nicely grow and the color just so perfect, just don't have the tendency to destroy it anymore, pause, pause,pause...for a while, is really feel good and refreshing when first seeing it.

Well just leave it alone, plants do have the right to "live", but I can't guarantee how long it will stay there, hope to dig it out and put it somewhere on the garden.
