Square vs triangular spacing
In a square grid every plant sits at the corner of a square. In a triangular (staggered or offset) grid each row is shifted half a space, which fits about 15% more plants in the same area and gives fuller coverage — popular for ground cover and hedging.
Use the spacing shown on the plant label, which is based on the plant's mature spread.
