 It's midsummer in Alaska, and of course, now that your garden is blooming beautifully, you've got to take care of your landscaping needs, and Alaska Sourdough Pea can do that for you, too. They have sand, topsoil, gravel, and even those kind of big rocks. They're almost boulders that you can use to make a good retaining wall, maybe something decorative at the corner where you live or at the driveway.
