Annual impatiens typically last for one full growing season in most U.S. zones. This means that they will grow, bloom, and eventually die within a span of one year. They are called “annual” because they complete their life cycle within this time frame.
The lifespan of annual impatiens can vary slightly depending on factors such as weather conditions, care, and maintenance. In general, they will start blooming in late spring or early summer and continue to produce flowers until the first frost of fall. During this time, they can provide a beautiful splash of color to gardens and landscapes.
Once the frost arrives, the cold temperatures will cause the annual impatiens to wither and die. Unlike perennial plants, they do not have the ability to survive the winter and regrow from their roots or base. As a result, they need to be replanted each year if you want to enjoy their beauty in your garden.
It’s worth noting that there are some varieties of impatiens, known as New Guinea impatiens, which are considered a hybrid varietal. These hybrids are a cross between different species of impatiens, resulting in plants with unique characteristics and traits. New Guinea impatiens are known for their larger flowers, vibrant colors, and tolerance to heat and sun.
Unlike traditional annual impatiens, New Guinea impatiens can sometimes be treated as a perennial in warmer climates, specifically in Zones 10 through 12. In these regions, where the winters are milder, New Guinea impatiens can be cut back and properly cared for to encourage regrowth in the following year. However, even in these zones, they may still benefit from being replanted annually to ensure optimal growth and performance.
Annual impatiens last for one full growing season and need to be replanted each year. New Guinea impatiens, on the other hand, are considered a hybrid varietal and can sometimes behave as perennials in warmer climates.
