Have you had trouble keeping your plants alive throughout the summer growing season? Gardening in Oklahoma can be challenging in the summer months, for sure; bugs, heat, low rain, etc. all are factors that can severely affect your plants. Here are ten low maintenance plants you cannot kill! All of them are suited to our frost zone 7. Although the season is winding down now, plan ahead for next year!
Marigolds are one of the hardiest flowers that you can plant in your garden, which is why they are seen at nearly every home in the country. In fact, they are well known by gardeners to be a drought tolerant plant that can handle a lot of heat. Marigolds are annual flowers, so when the first frost hits, their growing period ends.
If you are looking for a plant to brighten your garden, the daylily is a great option that comes in a plethora of colors. These blooms will only last for a day, but they will continue to appear throughout the summer in our zone. These plants grow best in full sun, and they are able to tolerate drought conditions, which means that even if you forget to water these plants, they will continue to do well.
One of the most low-maintenance plants that you can consider for your garden is cosmos. These hardy plants are so easy to grow that they can seed themselves and grow with very little care in the warmer areas of the country. They do best in full sun, but they will also grow in partial shade, which means they can be planted anywhere in your garden.

Begonias are colorful flowers that grow well in Oklahoma, but remember they are sensitive to frost, so will not last past our first cold snap. This is a plant that loves the shade, so if you do not have a sunny garden, this plant will thrive here. It can also tolerate drought conditions and a lot of sun, so regardless of where you plant it, the begonias will grow. This is a great option for a garden that does not get a lot of sun.
Hostas are very adaptable plants that grow in shade to part shade, and this is a plant that does not mind cooler temperatures. When the weather is below 40 degrees Fahrenheit, this plant will go dormant through the winter and reappear again in the spring. They tend to do well in partial sun, especially the golden varieties with foliage that turns yellow in direct sunlight.
Goldenrod is a plant that is mostly known in its wildflower form, but it will also make a great addition to any garden because it will basically grow on its own. Their tiny yellow blooms add brightness to your garden, and they will attract butterflies and bees as well. These plants can handle full or partial sun, and they are drought-tolerant, deer-resistant plants that can easily grow to be eight feet in height.

The coneflower grows up to five feet in height, which is perfect for adding depth to your garden. These plants grow well in Oklahoma; they prefer full sun, but they can grow in shady conditions as well. Their blooming period begins in early summer and continues until or through the first frost of the year.
If you are looking for a lot of ground cover in your garden, yarrow is a plant that spreads quite rapidly. Growing up to four feet tall, yarrow can handle a lot of heat, and it is also drought-resistant, so if you forget to water it, it will still survive. Yarrow comes in yellow, white, pink, and red blooms, and will continue throughout the entire summer, especially if you deadhead the plant.
Zinnias are very adaptable plants that can grow to be up to three feet in height. They prefer full sun, though they will grow in the shade as well. These are drought tolerant plants that will attract butterflies to your garden. The blooms from this plant last all summer, and they can be red, pink, orange, purple, yellow, and white in color.

This plant is often seen as a wildflower, but they can add some lovely orange, yellow, and red blooms to your garden environment. They will also attract bees, butterflies, and other pollinators to your garden.
