Flowers for Flower Boxes

Flower boxes enhance the appearance of a home's exterior. These mini-gardens, usually mounted under window frames, form a charming feature and accent piece. Selecting the right flowers is slightly tricky--the best are brightly colored flowers that stand out even at a distance, but require little care and maintenance. The flowers also should not grow too tall and obstruct the view from the window. Mix a variety of tall, cascading and bushy flowers for a varied yet colorful display.

Impatiens

Renowned as landscaping flowers, impatiens come in white and shades of red, purple and pink. The flowers bloom all through the summer. Impatiens grow up to 10 inches tall, and are easy to maintain. They adapt to any type of well-drained soil. Many gardeners plant them in hanging baskets because they make great container plants. Although impatiens prefer partial shade, some cultivars grow in completely shaded areas as well. Plant impatiens in a flower box surrounded by tall trees that shade it during the day.

Lily of the Nile

Lily of the Nile (Agapanthus praecox), or African Lily, is an evergreen suited for container gardening. This perennial plant contains strap-like leaves that grow over 12 inches long, and trumpet-shaped flowers up to 2 inches wide that bloom all through the summer. Plant lily of the Nile in a flower box that gets full sun. Water frequently to keep the soil evenly moist.

Geraniums

Gardeners grow geraniums in hanging baskets, planters, pots and flower boxes. These hardy annuals have white, blue, pink or red blooms, and fuzzy green leaves. Drought-resistant geraniums prefer well-drained soil and a sunny or partly shady spot. Plant either bushy or trailing cultivars of geraniums in the flower box with other annuals, such as petunias, vinca vine, verbena and lobelia for a varied blend. Water deeply but infrequently, allowing the soil to get dry between waterings.

Sweet Marjoram

Sweet marjoram (Origanum majorana) is a hardy perennial suitable for container use. This multi-branched plant grows up to 2 feet high, with fragrant 1-inch-long leaves and tiny flowers. Grow sweet marjoram in well-drained soil in a sunny spot. Water the sweet marjoram plant frequently.

Petunias

The petunia is one of the most commonly grown flowers in home gardens. Petunias make good container flowers for several reasons--they produce vibrant blooms, are low-maintenance, withstand high heat and drought, and are resistant to most pests and diseases. These flowers prefer full sun to partial shade and come in hues of pink, white, blue and red. Petunias have tall and trailing varieties that add color and beauty to a flower box.
