Creating a beautiful and productive urban garden is entirely possible by skillfully mixing ornamental and edible plants in your planter boxes. This approach, often called "edible landscaping," maximizes limited space while providing both visual appeal and fresh produce. Start by selecting a large container with proper drainage holes—at least 18 inches deep for adequate root growth. Consider the "thriller, filler, spiller" design principle: place a tall ornamental grass or flowering plant as your thriller, surround it with bushy herbs like purple basil or sage as fillers, and allow trailing plants like nasturtiums or strawberries to spill over the edges.
Companion planting is crucial for success. Many edible and ornamental plants benefit each other when paired correctly. Marigolds planted alongside tomatoes deter pests with their natural compounds, while lavender can protect brassicas from moths. Color coordination creates visual harmony—try pairing silver-leafed lavender with deep purple kale, or bright yellow calendula with scarlet runner beans. For texture contrast, combine feathery carrots with bold-leaved hostas.
Remember that most edibles need at least six hours of sunlight daily, so position your containers accordingly. Use high-quality potting mix enriched with compost, and implement consistent watering practices since containers dry out faster than ground soil. Regular harvesting of herbs and vegetables will encourage continued production while maintaining your garden's aesthetic appeal. With thoughtful planning, your urban planter can become a stunning, multi-functional garden that nourishes both body and soul throughout the growing season.
