Blue Oat Grass (Helictotrichon sempervirens) and Kangaroo Paw (Anigozanthos). The silver blue of the grass really sets off the orange: exponentially more striking than Kangaroo Paw on its own. Kangaroo Paw likes sun, heat, and drainage. If you’ve got clay, you’ll probably need to amend your soil. It’s supposedly a perennial but mine never make it through our wet bay area winters so I think of it as an annual. A beautiful, irresistible, expensive annual. At least the Blue Oat Grass is easy.
