In this article, we’ll look at what the best flowers for window boxes are, as well as a few suggestions for how to make the most of them. Whether you’re looking for a colorful plant for spring or a colorful accent for fall, you’ll find a great choice for your window box in this guide. From Impatiens to Caladiums, to Pelargoniums and Petunias, there’s a flower for any taste.


Impatiens are dependable shade-tolerant plants that will create a mound of colorful blooms. They don’t require deadheading and are easy to care for. Listed below are some tips to keep impatiens looking their best. Impatiens love shade and should be planted in partial shade, out of direct sunlight, and in good potting soil. You can also try begonias, which are shade-tolerant and more popular in home gardens .

They like shady spots but can adapt to direct sunlight. They also need some time to establish themselves in the window box. Impatiens should flower continuously from spring through fall. Once established, impatiens can be transplanted to an outdoor container and will last for several years.

Coleus tolerates heat and is hardy in a variety of conditions, but it’s best not to place them where they are exposed to direct sun. Shade-tolerant plants include rex begonias and tuberous begonias. Both types of begonias make great window-box plants.


These low-maintenance perennials can grow all year around. To grow them indoors, you should purchase a tuber and grow it in a small pot. Once the tuber grows large enough to support the plant’s entire root system, step it up and out of the pot. Stepping up the plant encourages excessive root growth and little leaf growth. In flower arrangements, caladiums make a beautiful contrast between the bright colors of the leaves and the rounded form of the flowers. The cut flowers can remain fresh for weeks if kept in filtered water.

Caladiums can be grown in deep shade or partial shade. Full sun will result in a drab plant without vibrant colors, but partial shade is a good option. While full-sun Caladiums need a lot of water to stay healthy, partial-shade plants will retain moisture while being protected from the harsh sunlight. Regardless of the type of sun exposure your caladium will need, this versatile plant is a perennial that will add beauty to your window box.

If you plan to plant caladiums in your window box, be sure to follow these care instructions. You should provide adequate moisture to the soil, but not soggy that it prevents roots from growing. As the plants grow, they will require more water. Once established, Caladiums require regular watering and balanced liquid fertilizer every two to three weeks. If you are planning to transplant your caladiums, be sure to harden them first by placing them in indirect sunlight for a few hours.


These blooming plants are great for window boxes, as they can grow indoors or outdoors. They come in bunches, which makes them easier to maintain.

In addition, petunias need less water than most plants.

When considering plants for your window box , petunias are the best choice. They bloom throughout the summer and come in a variety of colors. The popular Queen of Hearts variety is available for as little as $3.19 in a four-inch pot. A good accent plant is coleus. It comes in a variety of colors and grows to a height of 1 to 3 feet.

Their bright colors will make your window box look beautiful no matter where you put it.

If you want to grow a beautiful flower in a window box , choose one that requires very little maintenance. Choose a variety that flowers in a long season and blooms often, so you won’t have to deal with a month or two of boring green leaves. Also, avoid plants that are taller than a window box, as they will block the light from the inside. You can also choose some other plants that require little to no maintenance, such as petunias, which will last a long time.

Choose flowers that match the house. Colorful flowers always look best in window boxes, and geraniums have a bright red and yellow color that will stand out against the gray and white of the building. For a more subdued look, choose plants with multiple textures. Plaids and Poppies, for example, show how one type of flower can create a visually striking window box. In contrast, the Old Cape Barn demonstrates how a single type of flower can work well with another type of floral plant. For a dramatic effect, try tulips. These are dramatic, but not moody, and the shades of blue on the house offset them.

Once you have a healthy plant, store the cutting in a warm, dry place. Once it has a good root mass, you can transplant it outdoors in spring.

The Buenos Aires Verbena blends in well with naturalistic flowerbeds and combines perfectly with lemon verbena. Verbenas need good drainage and full sun to thrive and should be planted in soil that drains well.

For the most dramatic flower displays, opt for tricolored verbena. These flowers are characterized by white, lavender, and purple centers, and they don’t need deadheading. Also known as Sparkling Rose, these flowers bloom from early spring until frost. The tricolored variety is compact and vigorous, and does equally well in containers as in the garden. And if you don’t want to deal with deadheading, you can use the flowers in massed arrangements.

Petunias are summer’s workhorses, and they will keep on pumping out vibrant blooms even in the hottest weather. You can also choose Creeping Jenny, also known as moneywort, for its dense foliage and trailing vine appearance.
