An ubitquitous, easy, gardeners' favorite!
Sea Thrift is present all across the northern hemisphere, anywhere that is close to the sea. It often grows next to the ocean, and is adapted sell to salt and the poor soils that can be found there. In the Seattle area, it can also be found in meadows and glacial outwash prairies. Seasides are harsh places for plants, so if Sea Thrift can survive there, it can probably survive in your garden.
Sea Thrift has low, clumping, grass-like leaves which can turn a reddish color in the winter. In spring, light pink spheres of flowers float about a foot off the ground. These are well-loved by bees and butterflies.
