Step-by-Step Creation Method

Source a large, wide whitewashed wooden planter box or 18-inch glazed light blue ceramic pot with clear drainage holes. Fill the container two-thirds full with an acidic potting soil mix designed to support deep blue color development in mophead hydrangeas. Center a large, blooming blue mophead hydrangea plant firmly into the middle of the container, taking care not to disturb delicate root structures. Plant two clumps of slender blue fescue grass directly behind the hydrangea to create wispy vertical contrast behind the broad blooms. Plant trailing silver falls dichondra along the front edge of the soil, allowing silver stems to spill over the whitewashed wooden rim. Position the container on a morning-sun, afternoon-shade section of your front porch, watering consistently to maintain even soil moisture without waterlogging roots.
