I’m excited about a new element in the streetscape, sidewalk gardens. More and more frequently, I pass sections where the sidewalk has been removed and small gardens have been planted even where there are no street trees. Here are blooming yarrows, geraniums, sages, and lavenders. There are dramatic effects with New Zealand flax and muscular succulents. Grasses, wallflowers, and California natives like hummingbird sage or ceanothus, thrive in a profusion of colors and textures.
