Tiny plants– Easy to care for plants that can be grown to add green to the color of your design. Succulents are a popular choice for their ease of care and hardiness.
Grass– In spaces between rocks and other elements of your garden, it’s an option to include artificial grass or the real thing. If you’re going for a super easy to care for option, artificial is the way to go.
Wood– Incorporate wooden elements whenever you can. Tiny breaks of space using wood adds a visual sync to the design.
