Can Mediterranean gardens work in Washington's climate?

Washington's zones 6-9 offer excellent conditions for Mediterranean gardens. Many authentic plants including hardy lavenders, rosemary in protected zones, and classic herbs thrive. Long growing seasons, hot summers, and Pacific Northwest basalt and granite resources create beautiful Mediterranean landscapes.

What plants work best in Washington Mediterranean gardens?

Hardy lavenders, rosemary in zone 7-8 areas, santolina, Jerusalem sage, thyme, oregano, and rockrose in warmest zones all thrive in Washington. Many authentic Mediterranean plants perform excellently with modest adaptation.

How much water do Washington Mediterranean gardens need?

Established Mediterranean gardens need deep watering every 7-10 days in summer, less in spring and fall. Many plants thrive on modest irrigation once established. Expect 30-50% less water than traditional landscapes.

When should I plant in Washington?

Fall planting (September-October) is optimal in zones 6-9, allowing winter rains to establish roots before summer heat. Spring planting (March-April) also works. Both seasons support Mediterranean plant establishment.

What makes Pacific Northwest basalt and granite special for Mediterranean gardens?

Pacific Northwest basalt and granite provides authentic regional character while creating Mediterranean aesthetic. This beautiful stone withstands Washington's climate perfectly, offering durability and visual appeal. Using local stone honors regional geology while achieving Mediterranean design principles.

How do I adapt Mediterranean style to Washington's unique conditions?

Address humidity with good air circulation and drainage, select varieties proven in zones 6-9, provide modest winter protection for tender plants, and embrace Washington's long growing season. The moderate climate offers excellent Mediterranean potential.
