It is usually separated by both the rhizomes and the serpents, creating a dense lawn; its shoots: serpents and rhizomes, appear especially throughout the spring, just like during late summer, growing upright and erect, although in early spring they are usually more recumbent.

Throughout the winter, few new leaves are born; however, most of the rhizomes eventually become shoots of other rhizomes below the soil surface. They may branch out at various times throughout the year, since in general, the life time of individual rhizomes usually extends over 2 growing seasons, so their total life span as well as that of their terminal release does not normally reach 2 years.
