What grows here?

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

• 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.
• Light: About 18.2 moles a day, against an ideal of 22. This is the right light band.

Watch for: Narrow forms lose their shape if the top is ever cut. Buy the mature height you want.

Examples, not recommendations: Columnar hornbeam; Italian cypress in mild dry climates; Upright yew in cool climates. What is right here is a question for a nursery that can see the site.

Dense all year, and it wants more width than people allow for.

• Moisture: This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does.
• Light: About 18.2 moles a day, against an ideal of 24. This is the right light band.
• Reflected heat: Surface heat here is not the limiting factor.

Salt air is a different problem from wind, and this is the group that solves both.
