Simplicity in planting combinations
This photo is in complete contrast to the riotously colorful garden shot I posted a day ago here, and in some ways is even more satisfying to me as a garden composition. I tend to use a lot of silvery/white/blue foliage in garden designs here in California because they can look so good year round, and typically don't require much pampering because there foliage color actually is an adaptation to our long dry summers and sunny, dry conditions. This Cotyledon orbiculata v. longifolia along with Blue Sheep Grass is one of my favorite combinations, and is particularly useful in narrow hell strips along the sidewalk/street. I find the cushiony grass actually helps to protect the succulent foliage from damage with people getting in and out of their cars, as this is a high traffic parking area so close to the local metro rail line,(called BART here locally). Aristea inaequalis is another bluish foliaged flowering perennial I like to add to this mix.
