Ice plants are perennials, meaning they come back every year. However, it’s important to note that the hardiness zones of ice plants can vary depending on the species. Hardiness zones indicate the specific climate conditions in which a plant is able to survive and thrive. Therefore, it’s crucial to select a species of ice plant that is suitable for the perennial nature of your climate.
Ice plants, also known as Delosperma, are a diverse group of flowering plants that belong to the Aizoaceae family. They are native to South Africa and have gained popularity in gardens and landscapes around the world due to their vibrant and colorful flowers, as well as their ability to tolerate drought and poor soil conditions.
When choosing an ice plant species, it is important to consider your specific hardiness zone. The United States Department of Agriculture (USDA) divides the country into different zones based on average minimum winter temperatures. Ice plants are generally hardy in zones 5 to 9, but this can vary depending on the species.
In colder climates, such as zone 5, it is advisable to choose hardy ice plant species like Delosperma cooperi or Delosperma nubigenum. These varieties are more tolerant of freezing temperatures and are more likely to come back year after year.
On the other hand, in warmer climates like zone 9, you have a wider range of ice plant species to choose from. Delosperma basuticum and Delosperma congestum are popular options for these regions. These species thrive in hot and arid conditions, making them excellent choices for landscapes with full sun exposure.
In my personal experience as a gardener, I have found that ice plants are generally reliable perennials, especially when grown in their appropriate hardiness zones. However, it is worth mentioning that certain factors such as extreme weather conditions, poor soil drainage, or improper care can affect their ability to come back each year.
To ensure the longevity of your ice plants, it is important to provide them with the right growing conditions. They prefer well-draining soil and full sun exposure. Avoid overwatering, as excessive moisture can lead to root rot. Additionally, regular pruning and deadheading can help promote new growth and maintain a tidy appearance.
Ice plants are indeed perennials that have the potential to come back every year. However, it is crucial to choose a species that is suitable for your specific hardiness zone. By providing the appropriate growing conditions and care, you can enjoy the beauty of these vibrant and resilient plants in your garden or landscape for years to come.
