The crushed-shell path that keeps moving

I already own this. Where should it go?

The same reasoning read backwards. Every spot you have marked, ranked against what this plant actually needs — including the answer that nowhere here suits it, which is cheaper to hear now than in three years.

You already own it

What have you got?

The classic answer to a sightline when there is no room for a hedge.

Nowhere on this property suits narrow upright evergreen screen. That is a real answer, not a failure to find one, and it is cheaper to hear it now than in three years.

What would have to change

The ground stays wet longer than this tolerates. Raising the root zone is usually cheaper and far more reliable than trying to make the ground below drain.
Reflected heat off the paving or a wall is above what this takes. Either move it off the hard surface or change the surface.
This spot stays wet well past what this group survives in winter.

The corner that goes green

wrong place

About 31.1 moles a day. Midwinter direct sun is about 4 hours, counted on its own day, not inferred from the 12 hours of high summer. Against a minimum of 8 and an ideal of 22.

Moisture: This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does.
Hardiness: Zone 9.1 is outside this group's usual range of 5 to 9. Hardiness is a floor, not a plan.

Examples of what this group covers, not recommendations: Columnar hornbeam; Italian cypress in mild dry climates; Upright yew in cool climates. What is right in one region is a weed in the next, and only a nursery that can see the site knows which.
