Plants are hard work, they take a lot of time and patience. No matter how hard you try to look after them, something can always go wrong. However, we all love having beautiful gardens with a lot of plants and flowers. They make your backyard look splendid and rich. When decorating your garden, you must always envision it first, so the outcome doesn’t disappoint. Even the most enthusiastic gardeners sometimes don’t have enough time to look after plants, so it is always good to have some low-maintenance greens in your backyard.
To help you choose, here are 17 impossible-to-kill outdoor plants:
Table of Contents
Yarrow
Other plants may wilt in the hot, humid, dry summer, but the drought-tolerant yarrow will continue to flourish and look fantastic. This perennial has a negative reputation for being excessively hardy, since it may be difficult to keep it from spreading like wildfire. (This is, of course, due to the main fact that the plant possesses rhizomes that send out lateral branches.)
However, not all types are as aggressive, so grow yarrow in your garden for ferny leaves and tiny clusters of white-to-red flowers if you don’t mind its quick expansion.
Spider Flower
If you have spider flowers in your garden, you’ll probably have them for the rest of your life—for better or worse. You may absolutely try growing this annual from seed: simply scatter the seeds anywhere you like, and you’ll almost certainly get an abundance of gorgeous, white-to-lilac flowers in return. The plant’s name comes from its spider-like blossoms, which have long, thin filaments that resemble legs.
Tickseed
Tickseed is unaffected by heat, humidity, or drought, and neither is bad soil. This perennial thrives in almost any situation, which might be a disadvantage when it’s unwelcome. Tickseed is a common wildflower that blankets meadows and fields with masses of yellow and orange daisy-like blossoms. It is virtually tough to kill due to its drought tolerance and capacity to flourish on rocky, sandy soil. Tickseed, although its little stature, offers wonderful colors of sunshine to any garden.

Cosmos
You will probably be hard-pushed to find a more laid-back flower than this annual. Simply scatter some seeds in your garden, and in no time, you’ll have an abundance of silky ray flowers. Cosmos, cousins of the marigold and daisy, are recognized and adored for their unflappable, unkillable temperament. Even under poor soil conditions, they’ll flourish.
Cosmos are an annual flower that blooms in the summer. Butterflies adore them, so don’t be shocked if you see large swallowtail butterflies feeding on them.
Mexican Sunflower
The Mexican sunflower, which is a misnomer because it is not a member of the sunflower family, thrives in dry, hot environments. These hardy annuals grow quickly, are simple to seed, and are deer-resistant. Hummingbirds, butterflies, and other pollinators are likely to visit your garden since it is a nectar bloom. Mexican sunflowers grow hundreds of red-orange, daisy-like blooms from mid-summer through the first frost of October, and are called for their constantly warm region of origin.
Russian Sage
This plant was chosen perennial plant of the year by the Perennial Plant Association in 1995, largely because it is drought-tolerant and has few disease or pest concerns. Its fragrant periwinkle, extremely lavender-like blossoms will attract gorgeous butterflies and bees to your garden, yet it will keep troublesome deer away. The woody subshrub may also survive in a wide range of soil types, so it doesn’t require perfect circumstances to look beautiful.
Hens and Chicks
Gardeners adore this perennial plant, which is closely connected to the succulent family, not only for its distinctive leaves, but also for its capacity to thrive in a variety of situations, including sand, rocky soil, and mild or hot weather. In the summer, the main section of the plant (the hen) sends up a robust flower stalk. As the plant grows, little offshoots (chickens) will sprout all around the hen. Its leaves are generally red, green, or blue in color.
Moss Rose
Moss rose, a hybrid between a rose and a cactus, prefers hot, dry desert conditions—the hotter and dryer, the better. It is unaffected by harsh sunshine, and it rarely has to be watered since it stores water in its fleshy leaves and stems. Moss rose has cactus-like blossoms and succulent-like leaves that are delicate but prickly. Despite the fact that it is an annual, it frequently reseeds.

Butterfly Weed
Butterfly weed, so named because it is a host plant for monarch butterflies, is drought-tolerant and thrives in a variety of environments, including woodlands, prairies, and dry garden beds. Though the clumping perennial attracts a lot of butterflies, it repels unwelcome creatures like deer and rabbits. The milkweed plant develops into a joyful shrub that is approximately one or two feet tall and covered with colorful, fluffy orange-to-yellow clusters.
Goldenrod
Goldenrod is a wildflower that grows in meadows, fields, and parks. It thrives in a range of circumstances, including wet, dry, hot, and cold. In particularly humid situations, it might, however, develop the fungal illness of powdery mildew. Because it lacks large, showy blossoms, this perennial is sometimes overlooked by gardeners. From late summer to fall, it produces delicate, allover golden flowers that are attractive to pollinators.
Daylily
The daylily is a drought-tolerant, resilient, and high-impact perennial whose individual blooms survive only one day, as the name implies. This plant is rarely afflicted with illness and tolerates, if not thrives, neglect.
It has the attractive leaves of ornamental grass and produces lovely, colorful blossoms. While the petals of the daylily are transitory, the plant produces an almost unending supply of blooms throughout the summer. Daylilies come in a variety of hues, from canary yellow to scarlet.

Marigold
The marigold may win the prize for being the garden’s most drought-resistant and heat-tolerant plant. These vivid pom flowers endure and grow no matter how hot the days get.
The genus, of course, includes both kinds, annuals, and perennials, and belongs to the sunflower family. The warm-colored flowers, which resemble carnations in appearance, bloom early and last all summer. They are excellent companion plants for tomatoes, eggplant, peppers, and potatoes, as well as insect and pest repellents. Plant several various hues of marigolds in one location for a spectacular show.
Begonias
Begonias are brightly colored flowers that come in over 1,800 distinct varieties!
Velvety, stunning blossoms in vivid reds, pinks, yellows, and white adorn these winter plants.
Begonias, unlike Goldenrod, do not require much sun. They thrive in the shade and can withstand droughts as well.
Too much water, cold weather, and direct sunlight are all bad for begonias. It is preferable to water them less regularly and keep them in the shade for long periods of time.
Snapdragon
These plants, in addition to having a groovy name, can tolerate extreme temperatures if properly fed. Antirrhinum alludes to the seed pod’s likeness to a calf’s nose, and its scientific name means “like a snout.” Snapdragons need larger bumble bees for pollination since the flower apertures are securely locked and require more pressure to open than a honeybee can offer.
Snapdragons come in a variety of colors and may be planted in full sun or partial shade. This flower is not only beautiful for human eye, but it also requires very little upkeep.

Coneflower
Birds, butterflies, and bees all love the coneflower. They come in bright red, hot pink, and purple colors that will make your yard stand out.
Coneflower, which grows to around one and a half meters in height, is ideal for creating depth in your landscape. The flower thrives in direct sunshine, although it may also thrive in the shade.
They blossom in the early summer and persist throughout the winter.
Silver Ponyfoot
Silver ponyfoot is a delicate vining plant that flows overhanging pots or the edges of a retaining wall, despite the main fact that it is not a blooming plant. Their silvery green foliage will make a stunning backdrop for other plants with brighter colors, such as the marigolds described earlier. It thrives in full sun, and sometimes in light shade, grows swiftly, and is drought tolerant. Although this waterfall plant is very hard to kill, it will not survive a harsh winter and must be taken indoors throughout the winter.
Caladium
This is yet another plant with eye-catching leaves that will delight and surprise your dinner guests. Caladiums come in a variety of colors, from red with white rims to purple, green, and pink. You can be suspected of owning a fake plant since they seem so different! While some kinds tolerate the sun, they need complete shade and a high level of humidity. They want wet soil but not standing in water, so let the top few inches of soil dry off before watering it again. It’s time to bring the caladium indoors for the winter when nighttime temperatures dip below 60 degrees.
It is always hard when you have a lot of options to choose from, and yet really frustrating when there are no options at all. This list provided you with some of the most famous impossible-to-kill plants.
