A garden within a garden
Each sub-garden is its own small area inside the bigger one. Memorials live inside sub-gardens, so the whole garden takes shape as you add people.
Add as many as you need
Two sub-gardens to begin with. Add more later — by generation, by side of the family, by connection, by whatever makes sense.
Rename and rearrange
Sub-gardens can be renamed, rearranged, or removed. Nothing about the layout is fixed.
