White PVC Window Box

Variety Of Forms and Shapes For Flowerboxes

Choosing the plants for your bay window box may be daunting, but you can design a breath-taking arrangement if you focus on the shapes of the flowers you plant inside.  By utilizing different plant shapes, your window gardening will take advantage of all the visual space available, creating patterns of both color and form.  When choosing flowers for window boxes, keep in mind the three primary shapes best suited to window boxes:

Trailing plants like Wave™ petunias, sweet alyssum and ivy geranium do a beautiful job of uniting the plants in front of your home with the window boxes to create a landscape that seems to slide seamlessly from your house and into the yard.  If you’re not a fan of shrubbery, these dangling dandies can still add a lot of sizzle to your home’s décor.

Choose plain window boxes to go with trailing plants since they’ll soon be obscured by foliage and flowers.  Extra deep window boxes will allow you to plant mounding or upright plants behind the cascading blooms.

Mounding plants add tidy splashes of color to your window boxes without being too much trouble to maintain.  Impatiens, dianthus and snapdragon are well-behaved choices for growing behind trailing plants or in front of tall, upright plants.  They also do great service on their own, provided you keep to one or two varieties.

Spice up a single-colored planting of mounding plants by planting them in an ornamental window box with scroll work or unique coloration.  You can extend the life of these practical works of art by inserting flower box liners before planting.

Upright plants aren’t as strong on their own as trailers or mounding plants, so try to match them with flowers from one or both categories.  Alone, upright plants can become leggy and look thin as they age, but by placing upright flowers in front of them, you’ll hide much of the potentially unruly foliage.

Trailing plants can do the same job if they mound slightly before tumbling over the edge of the window box.  Try salvia, sage or dwarf daffodil or iris behind mounding plants for a dramatic effect.  Upright plants can be enhanced with decorative flower boxes if you don’t overdo it – too much color and design can become chaotic quickly.

Homes of all sizes, shapes and styles will be enhanced by choosing the right flowers and window boxes.  Whether you prefer trailing, mounding, upright or a mix of plants in your planters, plant-filled window boxes bring color and charm into small spaces.

    Than you very much for your time and advice.

      I believe the flowers in this window box are: Calibrachoa (peach & lavender pink), petunia (blue), lysimachia (green & yellow foliage), lantana (Orange & pink combined, towards rear), & pelargoniums (pink)
      Happy window box gardening :)
