Drought-Tolerant Grasses for seattle Gardens

As climate patterns shift and summers grow hotter and drier - even here in the lush Pacific Northwest - more gardeners are turning to xeriscaping. This water-wise landscaping approach uses drought-tolerant plants to create gardens that are both beautiful and sustainable. At West Seattle Nursery, we’re proud to offer a carefully curated selection of xeric grasses that thrive with minimal water, perfect for our increasingly dry summers.

What Does "Xeric" Mean?

The term xeric refers to plants that thrive in dry environments with little supplemental water. Xeric grasses are ideal for xeriscaping, which is all about conserving water while still maintaining color, movement, and seasonal interest in the garden. Once established, these grasses require significantly less irrigation, making them a smart choice for eco-conscious gardeners.

Why Xeric Grasses in Seattle?

While Seattle is known for its rainy winters, summer droughts are becoming more frequent. According to the University of Washington’s Climate Impacts Group, the Puget Sound region is experiencing longer dry spells and hotter summers due to climate change [1]. This makes drought-tolerant landscaping not just a trend, but a necessity.

Xeric grasses are a great fit for Seattle-area gardens because they:

Thrive in full sun
Tolerate dry summer conditions
Require less water once established
Add texture, movement, and seasonal interest
