While green is not neutral in terms of color, it is neutral when it comes to planter color. With plants matching the planter, green makes the decor feel more cohesive and flowing – the plant color flows into the planter, and vice versa. In rooms that may be less decorated and more laid back, having everything flow together and having a planter that doesn’t distract or draw attention, gives a very cohesive and gliding aesthetic. Green signifies tranquillity and good luck, thus making it a common choice among people. You can place them anywhere; indoors or outdoors, depending upon your suitability.
