Window boxes filled with flowers and plants add an extra splash of color to any home. Place plants, flowers, herbs or vegetables in window boxes, and enjoy the beauty of your small garden. Select sturdy boxes that offer ample drainage for plants, and attach the boxes securely to your windows. A strong support system is a must, as boxes become heavier when plants are watered.
Impatiens (Impatiens wallerana) thrive in window boxes. Impatiens come in a range of colors, including white, reds, oranges, pinks and purples. They like moist soil and will flower continually from spring until fall. Pansies (Viola x wittrockiana) come in nearly every color imaginable and bloom from spring until fall. Purple Shamrocks (Oxalis purpurea) have large purple leaves and white or pink blossoms. They bloom throughout the spring. Fuchsia (Fuchsia cultivars), coleus (Solenostemon scutellariodes) and caladium (Caladium x hortulanum) love shady areas and flourish in window boxes.
Sweet alyssum (Lobularia maritima) have honey-scented flowers of pink, white, purple and rose color. The alyssum blooms from late spring until the first frost of the season. Petunias are available in almost any color, require very moist soil and will bloom all summer. Verbena (Verbena x hybrida) loves the heat and will flower from mid-spring until the first frost. Verbena are spreading or bushy plants that produce purple, pink, red and white flowers. Vinca (Catharanthus roseus) tolerate dry and high heat conditions. They have white, lavender, rose, salmon, purple and red blooms that show from early summer months until the first frost.
Keep fresh herbs close to your kitchen by growing them in boxes just outside your window. Herbs do best when grown in partial to full sunlight. Sweet basil (Ocimum basilicum), parsley (Petroselinum crispum), rosemary (Rosemarinus officinalis), oregano (Origanum vulgare) and sage (Salvia officinalis) are easily grown in window boxes.
Plant chervil (Anthricus cerefolium), wild ginger (Asarum canadense), sweet woodruff (Galium odoratum) and angelica (Angelica archangelica) in window boxes located in shaded or partially shaded areas.
Growing vegetables in window boxes creates a small garden for those who don't have space to plant a full garden. Dark green Bloomsdale spinach, Early Red Ball beets, Jackson Lima beans, Bush Romano snap beans, White Sweet Spanish onions and Cherry Belle radishes will grow in 5-gallon-sized window boxes. Carrots will do nicely when planted in a window box at least 12 inches deep. Choose the Short and Sweet, Danvers Half Long or Tiny Sweet variety of carrot for your window box garden.
