In order to attract hummingbirds, it’s crucial to discover flowers that can thrive and flourish within your specific weather conditions. If the weather is excessively hot or cold, these plants may perish or fail to produce enough flowers for hummingbirds to gather nectar from.
The United States Department of Agriculture (USDA) has created a plant hardiness zone map that divides the country into 13 zones based on the average minimum temperature. Additionally, within each state, there are different zones. Each plant thrives in different zones and can tolerate minimum temperatures, but they cannot survive in conditions that are too cold.
Oklahoma, with its hot subtropical climate, falls primarily within zones 6 and 7 on the plant hardiness scale, except for the southeast region, which is classified as zone 8.
To address the issue of excessive heat, the American Horticultural Society has developed a plant heat-zone map, which indicates the average number of days an area experiences temperatures over 86 degrees F.
According to the plant heat zone map, Oklahoma falls within zones 7 to 9, making it suitable for the majority of plants that can tolerate these temperatures.
It’s essential to ensure that the plants chosen for attracting hummingbirds in Oklahoma have been verified for their ability to thrive in the cold and heat zones of the state. This ensures that these plants not only possess beautiful, nectar-rich flowers that hummingbirds adore but can also withstand Oklahoma’s weather conditions.
Keep in mind that plants recommended for higher-numbered hardiness zones may not survive the colder weather in lower-numbered zones without adequate protection.
Therefore, it is advisable to plant as many of these flower varieties as possible in Oklahoma to maximize the chances of attracting hummingbirds. Here are some examples of plants suitable for Oklahoma’s hardiness zone 6:
