What grows here?

The cheapest screening per metre and the best for everything that is not a person.

• Hardiness: Zone 10.2 is outside this group's usual range of 3 to 9. Hardiness is a floor, not a plan.
• Light: About 29.5 moles a day, against an ideal of 28. This is the right light band.
• Moisture: Moisture here sits inside what this group will accept.

Watch for: Mixed hedges take four years to be a screen and want cutting once a year to stay one.

Examples, not recommendations: Regional native hedging mixes. What is right here is a question for a nursery that can see the site.

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

• Hardiness: Zone 10.2 is outside this group's usual range of 7 to 10. Hardiness is a floor, not a plan.
• Light: About 29.5 moles a day, against an ideal of 30. This is the right light band.

Fast, tall, evergreen screening, and the one plant most likely to become somebody else's problem.

Wants a hot wall in summer and somewhere frost-free in winter, which makes it a decision about storage as much as position.

• Moisture: This spot sits wetter than this group tolerates. Wet feet kill far more plants than cold does.
