Best Flowers For Window Boxes

For a great-looking window box, you don’t just need to think of which flowers to add: you also need to consider a few little elements about your window. Elements such as the hours of sunlight the window gets if the window is in a shady area, the season you are installing the window boxes, your flower color preference, and many more. That is why we decided to help you in the process of selecting the best flowers for your window boxes under various factors.

Best flowers for sunny window boxes

When growing a plant, the most essential consideration is sun exposure. Flower plants that prefer full sun grow better in a south or west-facing window. Some of the sun-loving upright flower plants are:

  • Artemisia (Artemisia)
  • dusty miller (auricula)
  • lavender (Lavandula)
  • marigold (Tagetes)
  • opal (Lachenalia aloides)
  • bush basil (Ocimum minimum)
  • periwinkle (Vinca minor)
  • ornamental pepper (Capsicum annuum)
  • rosemary (Salvia rosmarinus)
  • salvia (Salvia).

Though you do not have to have them all in your box, you can have different plants on different windows of your choice.

How can we make having sun-loving trailing plants that make your window visually more appealing? You must include 2 to 4 trailing plants in your window boxes.

Some of the trailing plants to choose from are:

  • sweet potato vine (Ipomoea batatas)
  • nasturtium (Tropaeolum)
  • petunia (Petunia)
  • dwarf soapwort (Saponaria pumila)
  • thyme (Thymus)
  • prostrate rosemary (Rosmarinus officinalis)

What is more appealing than trailing flower plants?

Well, that could be climbing plants for you. These surround your structure to give it the best visual appeal it deserves. If that is what you are looking for, you can select from flower plants like:

  • Carolina jessamine (Gelsemium sempervirens)
  • honeysuckle (Lonicera)
  • golden hop (Humulus lupulus)
  • moon vine (Ipomoea alba).

Give these a try!

Best plants for shaded window boxes

Don’t have the sun on your windows? Do you have windows both on the south and north side? Don’t feel disappointed; not all plants love the sun equally. There are beautiful-looking flowers that thrive better in the shaded north-facing windows. A combination of trailing, climbing and upright flower plants are preferred by many flower lovers. However, you may also go for only one of the three.

  • Astilbe (Astilbe)
  • coleus (Coleus)
  • English daisy (Bellis perennis)
  • hosta (Hosta)
  • impatiens (Impatiens)
  • garden heliotrope (Valeriana)

  • Lenten rose (Helleborus orientalis)
  • snapdragons (Antirrhinum)

The above are some great-looking upright flower plants for your shaded windows. Add a few trailing flowers like:

One great combo for the fall is the trio of:

How do you arrange flowers in a window box?

The arrangement of a window box is very crucial to make it look appealing. You don’t just want to put plants here and there, but rather in an arrangement that looks beautiful and satisfying. You need to use your main plants like geraniums, salvia, or Angelonia in the background in the sun.

If you are using begonias put your box in the shade. Add filler annual plants like petunias in a wide range of colors, blue lobelia, or vinca in between the main plants.

Add trailing plants like sweet potato vine, ivies, or vinca vine in front of your main plants.

How many flowers should I plant in a window box?

The answer to this question depends on the size of your window and how many plants you want to place in the window box. As long as the plants have a good amount of light and are placed in a good location, they will be fine.

Are petunias good for window boxes?

Petunias are one of the most appealing additions to any window box. They come in various colors and textures to enhance the appearance of your window in any season. You can always add a pop of color with petunias!

Why add window boxes to your home?

In addition to offering a curb appeal to your structure, a window box has several benefits. Window box planters can be of any size and shape based on your choice and requirements. They are also easy to maintain. In addition to that, you can grow a wide variety of flowers and plants in a window box throughout the year.

What color should flower boxes be?

When it comes to selecting the color for your window box, go with a color that fits the style of your window and the house. The box can be a matching color to your window or your home as well. Of course, you can use a neutral color flower box, and let the color of your flowers make your box pop up. Use green foliage, as well as colorful flowers. I love adding pink flowers to mine, to give my boxes a romantic look.

What can you plant in a window box in winter?

Window boxes offer you a variety of options in the winter. You can plant junipers, false cypress, spruces, and arborvitae, pansies, violas, or snapdragons. You can also plant kale and cabbages to add some color variation to your winter window box.

What can you put in a window box besides flowers?

Window boxes are not limited to flowers alone. You may plant cabbages or other vegetables that require less space and work, conifers, berries, and even artificial flowers if you don’t have the time and energy to keep up with live flowers. You can also create a herb garden by your kitchen window.
