There are many plants that can tolerate heat, and they aren’t just the ones that you would expect. There are some tropical plants that will do well in hot climates, even if they’re not native to that area. Here are a few of these plants that you may be able to grow in your garden.
The Lantana is an excellent choice for use in borders, hedges, and rock gardens. The bright flowers come in a variety of colors and are fragrant. The plant is tolerant of dry heat and low water requirements.
You may have heard of sunflowers as a flower that flowers in the summer. But did you know that they can also be grown as a vegetable? Sunflowers are an annual plant that grows best in full sunlight but can tolerate partial shade as well. They make for excellent container plants because of their tall height and large size. The sunflower seed is actually the fruit of this plant – it’s commonly used to make oil for cooking or in salad dressings, but it’s also edible on its own. The seeds only contain about 18% protein, though they do contain some vitamin E and iron as well.
Okra is a heat-tolerant plant that can grow during the warm summer months. It is a perennial vegetable, so it will keep coming back year after year if you take good care of it. If you live in an area where the temperatures are consistently above 80 degrees Fahrenheit, then okra is a great option for your garden. If you’re looking for something to plant this spring or summer, consider planting some okra.
Melons can grow in containers and have the added benefit of being a good source of vitamin C. In fact, melons are so versatile that they can be grown even in greenhouses or on patios.
Peppers are a good choice for hot weather. They are perennial plants that will last for years and can be grown in containers.
Peppers are easy to grow and are good for container gardening. They do not need much water or soil, so they can be placed anywhere with a little sunlight, including on patios and balconies.
Cucumbers are a warm-weather crop, but they can tolerate dry heat. Cucumbers are a good source of vitamin C, potassium, and vitamin K.
Eggplant and other nightshades
Nightshade vegetables, including eggplant and peppers, are another good choice for a container garden. They can tolerate the heat and they’re easy to grow. They’ll also attract butterflies and hummingbirds if you plant them in your garden.
Eggplant is a good choice for a hanging basket because it can tolerate some shade; unlike tomatoes or squash plants which need full sun all day long, eggplants will produce fruit even when there are leaves and flowers shading its fruits from the sun.
Borage and other herbs
Borage is a plant that can grow in the sun with little water, and it also tolerates heat. Even though borage is a herb and not technically a vegetable, it’s good to know about because it can be used as an ingredient in pickles, salads, and smoothies. Because of its high nutritional value (minerals like calcium and magnesium), borage can also be grown in containers if you don’t have access to garden space. Borage attracts beneficial insects like bees and ladybugs with its bright blue flowers the butterflies think they’re pretty too.
Desert rose (Adenium obesum)
- A succulent plant, the desert rose (Adenium obesum) can withstand temperatures as high as 120 degrees Fahrenheit.
- The lifespan of this beautiful flowering plant is 15-20 years.
- Native to Africa, it is also found in the southeastern United States and is popular among gardeners in warm climates.
Aloe vera is a succulent plant that can tolerate drought, heat, and sun. It has a hardy nature and often grows wild in arid climates. Aloe vera is native to Africa but is now cultivated worldwide. The sap of the aloe vera plant contains an antibacterial agent called aloin, which can have therapeutic effects on the skin when applied topically.
Century plant (Agave americana)
One of the most hardy plants for hot weather, Agave americana has an extensive range that stretches from California to Texas. It is a fast-growing plant that can reach heights up to 15 feet in one year. This evergreen succulent thrives in dry, hot conditions and is drought tolerant.
The century plant’s thick fleshy leaves are gray with light green stripes and grow from its base in rosettes, or circular clusters. The leaves emerge as long green blades that eventually turn a rich purple color when they’re mature enough to flower, which happens every 3–5 years (the lifespan of each individual plant).
Cactus (various types)
Cacti are a favorite for people who want plants that can stand up to the summer heat. They come in many different shapes, sizes, and colors. Some cacti can grow as tall as six feet, while others are only inches tall.
There are also numerous varieties of cactus such as the aloe cactus, prickly pear, and Christmas cactus. All of these plants thrive outdoors in the spring through fall and require very little care or maintenance once they are established (no fertilizer is needed). They will survive temperatures above 100 degrees Fahrenheit but should be moved indoors if it gets too cold outside during winter months.
Paper flower (Psilostrophe cooperi)
- Paper flower is a perennial plant that grows in USDA zones 3-9. It reaches about 2 feet tall, has a long bloom period from spring through late summer, and grows well in dry soil or heavy rainfall. The plant’s white flowers will brighten up any garden space and are sure to draw butterflies.
Train vine (Ipomoea quamoclit)
Train vine (Ipomoea quamoclit) is a perennial plant that can grow up to 20 feet tall and wide, bearing green leaves and purple flowers. Train vine is fast-growing, hardy, and drought tolerant; it thrives in full sun or partial shade. Although train vine tolerates heat well, it does not grow in extreme heat areas such as deserts. Train vine can withstand cold temperatures down to 15 degrees Fahrenheit but will begin to suffer if temperatures drop below freezing for extended periods of time. The salt tolerance level of this plant varies depending on its location—in coastal regions, it may survive saltwater spray from the ocean during storms but be unable to tolerate salty soil at higher elevations inland.
Lantana is a tropical plant that can grow in a variety of conditions. In hot, dry climates, lantana is a good choice because it tolerates high temperatures and low humidity. Lantana also grows well in poor soil.
Texas sage ‘Silverado’ and ‘Green Cloud’
Texas sage (Lantana texana) is a perennial shrub that can withstand heat. It’s a native plant of the southwestern United States and Mexico, where it often grows in rocky hillsides. Texas sage has deep green leaves and clusters of tiny white flowers that are fragrant like citrus fruits.
Texas sages grow best in full sun with well-drained soil, but they will tolerate partial shade and dry conditions as long as they’re not too extreme. The plants tend to be drought tolerant once established. They flower throughout spring into fall, but especially bloom profusely during summer months when temperatures are highest outside your house.
Sweet olive tree (Osmanthus fragrans)
Sweet olive tree (Osmanthus fragrans) is a small tree or shrub that grows in U.S. Department of Agriculture plant hardiness zones 9 and 10 (meaning it can tolerate colder climates). It’s a slow-growing plant, but it’s also hardy, easy to maintain, and popular for landscaping. Sweet olive trees are often used as low-maintenance screening or privacy hedges because they grow quickly and provide dense cover for areas such as patios, porches, or decks. For the best results when planting sweet olive trees, make sure to choose healthy specimens with strong roots so they’ll survive transplanting without problems.
Plant sweet olives in rich soil with good drainage; they prefer partial shade but can tolerate full sun if given adequate water during dry periods when necessary so long as there isn’t too much heat stress on them from long hours of direct sunlight exposure during summer months — otherwise, you may end up killing off your entire crop.
