Low-maintenance landscaping starts with drought-tolerant plants. Not only do drought-hardy flowers help with water conservation, they also free up precious gardening time for other tasks. Plus they give you one less thing to worry about if you’re heading out of town for summer vacation. If you’re looking for an easier way to garden, these drought-tolerant flowers are a great place to begin.

What makes flowers drought tolerant?

A simple internet search for “drought-tolerant flowers” will generate plenty of leads, but they won’t all work in every garden. As with other plant categories, it’s important to choose flowers that will thrive in the unique climate and sunlight conditions in your garden. Before buying plants, learn your hardiness zone and whether your garden receives full sun, partial sun, or mostly shade. Then shop for annual and perennial flowers with these unique characteristics.


Plants that are native to your region are a great place to start. They’ve adapted over the years to withstand the temperature and moisture fluctuations that are unique to your climate. In addition to the climate, your garden’s sun exposure and soil conditions are important parts of the equation. Be sure to choose native plants for sun or shade as needed for your unique situation.

Plant combinations

Varied plant combinations can enhance drought hardiness. Combining taller and shorter plants throughout the garden helps both to be more resilient. Mixed plantings allow the individual plant types to utilize their forms and leaf structures in competitive and cooperative ways that result in a balanced garden habitat. Taller plants provide shade for shorter ones while lower plants shade the soil and protect taller plant stems from drying winds.

The same is true for plants with different root structures. Those with deep tap roots have access to moisture that shallow-rooted plants do not. But those with expansive lateral roots are the first to benefit from the smallest amount of new rainfall.

Physical adaptations

Even in diverse plantings of native species, certain flowers are simply more robust during drought conditions. This is directly related to their physical structure. Growth habit, leaf characteristics, root structure, and a variety of other details combine to give certain plants a leg up in dry conditions.

Short, stocky plants have less exposed surface area compared to taller, thinner ones. Similarly, thick leaves, especially when they have a waxy coating, offer less area for water loss through transpiration. Some drought-adapted plants incorporate tiny hairs along their stems or leaves that collect moisture from humid air. Others have succulent leaf and stem tissue that allows them to store excess water after rainfall and use it later.

Although there are countless varieties of grass, so many of them look the same. It can be difficult to find grass that really stands out in your garden. That’s where ornamental grasses come in. Ornamental grasses like pink muhly grass, purple fountain grass, and switchgrass can add color and texture to your garden borders just like flowers would. Wondering which ornamental grass to choose for your garden? Here are a few of our favorites!
What makes a grass ornamental?
You may think that all grass is ornamental. After all, we grow lawns because they look nice, not because we use them for food. You wouldn’t be entirely wrong in thinking that. Ornamental grass is still grass; it’s just grass that looks different. However, ornamental grass includes grass-like plants such as sedge, as well as true grass varieties.

Ornamental grasses come in a range of appearances besides the short, green look of classic lawn grasses. Often, ornamental grasses are tall, with some growing to 15 feet tall or more. Many are colorful and patterned, and they may have an interesting flower or seed head. Since there are so many varieties, there are ornamental grasses that will fit almost any garden or yard. Many gardeners use ornamental grasses as borders, but some varieties can make great additions to container gardens or flower gardens.

But did you know you can grow them outdoors as well? The care is a bit trickier, but they really stand out in a sandy outdoor succulent garden.

Planting Kalanchoe blossfeldiana
Like other succulents, drainage is important. Make sure you use sandy and well-draining soil before you begin planting. Kalanchoe blossfeldiana plants don't like to be crowded, so it’s important to space them correctly. They need at least 8 to 10 inches of room in order to grow properly. Choose a location that gets plenty of morning sun. However, they can burn under intense, direct light, so provide them with shade in the afternoon.

Caring for your Kalanchoe blossfeldiana
If you’ve kept Kalanchoe blossfeldiana as a houseplant before, then there are some care aspects you’ll be familiar with. They are sensitive to overwatering, so make sure to only water them when the top few inches of soil are dry. If overwatered, they can develop fungal infections, such as root rot.
