container-garden-design-ideas-uk-idea-gardening-cubtabThe curb appeal of a well-designed flower container shouts WELCOME to you and your guests! It is this time of year that gardeners flock to local garden centers in search of that perfect plant combination to adorn the entrance of their home.

A quick stroll through the plant selection can turn an exciting adventure into a frustrating disappointment, because you just don’t know where to begin with plant selection. Let me share a few tips to keep you smiling.

Sun or Shade

One of the biggest mistakes people make, is to forget to consider if the container will be placed in sun or shade. Sun lovers will not do well in shade, and shade plants will wilt in full sun. Always read the labels.


Begin by selecting a Thriller! This plant is the star of the show and should be somethingCosta-Farms-summer-container-garden bold, sexy, and beautiful. Find an interesting plant that will be your tallest and most exotic in your container garden. Some good picks: Canna, Banana Plant, Elephant Ears, or Purple Fountain Grass.


Next you need to look for a plant or several that will fill up the space. Search for something with interesting foliage or blooms. These plants should complement and not overpower the Thriller. Some examples are Coleus, Begonias, Heliotropes, and Lantana.


Now the fun part is selecting for example a Sweet Potato Vine, Creeping Jenny, or Nasturtium that will literally spill over the edge! Think of the Spiller as a plant that tumbles over and reaches out to anchor your pot to the ground so it looks like it belongs there!

Final Tips for Success

 Experiment with color, texture, and shape to make your container POP! Remember, this is your creation, so enjoy experimenting with different combinations before you finalize your plant selection. Arrange the plants in a cluster inside your cart so you can visualize how they will look together once you take them home. When planting, don’t be afraid to select a unique container but be sure it has ample drainage, and use a good potting soil mix. Once planted, use your finger as a moisture meter because most containers need water everyday once plants are established. Push your index just below the surface of the soil. If it is still moist, do not overwater since that can cause your plants to develop diseases. Also consider an all-purpose fertilizer once a week to keep them at optimum performance.

Good luck with your trip to the local garden center! Plant your container garden, and ENJOY the SHOW!

  1. Nasturtiums still rock! There are never too many of them. Rosemary works nicely as well. I think that some of the iceplants should be more popular than they are, even though some do not spill very well. I actually used the common freeway iceplant in large urns! It sounds silly, but it worked. (I would not recommend it where it might be recognized for what it is though; cheap.)
