Roundabouts, below, are the 2nd most common landscape design conceit. After Enfilades. Roundabouts add drama where 2 paths meet. Above, you can walk straight past the urn or make a right/left angle turn.
Not low maintenance, above? The urn, Queen's Pot, doesn't need to be planted. Perennials? Compost them & plant flowering shrubs. Turf? Create Tara Turf or rip it out & put in flagstones with creeping thyme in the cracks. (Shade? Plant dwarf mondo in the cracks.) Flagstones too expensive? Use #89 granite gravel.
Turn the Roundabout, above, into an Enfilade? Removed plinth from urn. Place bench or small summer house at far stone wall. Voila, you've made an Enfilade from a Roundabout.
Note: Paths, above, are hallways. Roundabout, above, is a foyer. Enfilade to fictional bench or summer house is a living room.
Honestly, this landscape design stuff is simply moving the couches & chairs & tables about.
Garden & Be Well, XO Tara
