Arranging vintage plants in an outdoor plant box can transform your garden into a nostalgic retreat. Start by selecting a mix of classic plants like ferns, ivy, and geraniums, which evoke a timeless charm. Use a tiered approach: place taller plants like foxgloves or hollyhocks at the back, medium-height varieties like lavender in the middle, and trailing plants like sweet potato vine at the front for depth.

Choose a weathered wooden or wrought iron plant box to enhance the vintage vibe. Add rustic touches like antique watering cans or moss-covered stones for extra character. Ensure proper drainage and sunlight for healthy growth. Rotate plants seasonally to maintain visual interest. With thoughtful placement and care, your vintage plant box will become a focal point of your outdoor space.
