No matter where you live, you can always count on bouts of hot, dry summer weather. That’s why it’s smart to fill your outdoor containers with drought-tolerant flowers and foliage plants. Sure, you can always water heavily and fill your pots with water-holding potting soil, but water-wise plants provide real container garden insurance. They will perform beautifully in the dog days of summer, saving you time, money, and worry.

Annual Fountain Grass (Pennisetum setaceum)
This elegant grass brings soft, airy height to containers and comes in lots of shades–from the multi-colored ‘Fireworks‘ to the russet red Red Riding Hood. By midsummer, it will produce ornamental foxtail plumes that persist into fall, even after they have turned brown.
Dichondra (Dichondra Silver Falls™)
This is the ultimate drought-tolerant spiller for impressive pots! The foliage effortlessly cascades down like a waterfall of silver and can be gently pruned back if it becomes too long. Its neutral color combines well with many other plantings.
Container gardens must have plants with the same sun and water requirements. For professional looking pots, go for plants with contrasting textures, heights, and habits, and devise a clear color scheme.
The standard container design formula includes a vertical, mounding or bushy, and cascading plant married in a complementary arrangement where plant heights blend into a fluid design. Contrasting leaf textures (fine, bold, airy, or spiky) will lend even more dramatic looks to your container. Choosing a smart color scheme is the final design factor.
Harmonious color choices make beautiful gardens. Colors may be contrasting but complementary (on the opposite end of the color wheel, such as purple and yellow, orange and blue, and red and green), warm or cool (reds, oranges, and yellows are warm and blues, greens, and purples are cool), or in similar hues (pink with pink, purple with purple, and so on). Neutral plants and flowers, such as tan-, white-, silver-, and black-hued plants, fit with practically any color group. Click here to view some great container designs by Proven Winners®.
Container Preparation & Care
Larger containers hold more water and give roots more space, so opt for big pots able to sustain your contained gardens—especially when growing multiple plants in one pot. Containers must always drain well, so make sure they have drainage holes in the bottom and a base able to hold residual water.
The proper mix also makes a difference. For best performance in hot, dry weather choose Black Gold® Moisture Supreme Container Mix or OMRI Listed® Black Gold® Waterhold Cocoblend Potting Mix. Both contain natural ingredients that hold water well. Adding a slow-release fertilizer at planting time will also boost performance.
Water-wise plantings require less water, but they still need timely irrigation. Your watering plan will depend on the size of your pot and the plants chosen. Those planted in large containers with water-wise plants often require water every three days or so. If your plants look lush and healthy, you know you are giving them what they need.
