Right plant, right place

Will Trailing rosemary grow at your Arizona property?

Excellent on a wall, terrace, or slope where stems can cascade. Give it air movement and sharp drainage rather than a low, soggy basin.

Best regional fit: Urban core · USDA 9b–10a, Valley suburbs · USDA 9a–9b, Desert outskirts · USDA 8b–9b, High desert · USDA 6a–8b.

Light

Full sun is best. In the hottest reflected courtyards, relief from late-afternoon sun can improve appearance.

Water

Low to moderate. Allow the root zone to drain between deep irrigations; rosemary declines in chronically wet soil.

Harvest

Use fresh or dried leaves for savory cooking, infused oils, and aromatic garden edges.

Planting & stewardship

1
Plant slightly high in well-drained soil and keep the crown clear of wet mulch.
2
Harvest or tip-prune regularly to encourage dense new growth without cutting hard into leafless wood.
3
Avoid overhead watering late in the day and do not combine it with high-water plants on the same valve.
4
Let some blue flowers remain for bees before the next shaping prune.
