Because Dwarf Mondo Grass maxes out at about 3 inches tall, you never have to mow or trim it. It stays at that height forever. It’s the #1 plant used to fill the gaps between flagstones or pavers. It can handle light foot traffic and won't get tall enough to trip over. Dwarf Mondo thrives in the shade. It is the perfect choice for under a large tree or on the north side of your house. It stays dark green all through the Oklahoma winter, providing a lush look.
