Morning glory plants have the ability to reseed themselves and come back year after year on their own. However, this can vary depending on the climate and growing conditions. In areas that experience temperatures below 45 degrees Fahrenheit (7 degrees Celsius), morning glories are typically grown as annuals, meaning they complete their life cycle within one year. In these colder regions, the plants will die off in the winter and will not regrow the following spring.
On the other hand, in warmer and more tropical climates, morning glories can behave as perennials, meaning they have the potential to come back year after year without needing to be replanted. These regions provide the necessary conditions for the plant to survive the winter and regrow from the existing root system or seeds that may have dropped the previous year.
Personal experiences with morning glories can vary depending on the location and climate. In my own garden, which is in a temperate zone with cold winters, I have found that morning glories do not come back on their own. However, I have heard from gardening friends in warmer areas that their morning glories do reseed and come back reliably each year.
It’s important to note that even in areas where morning glories are considered perennials, there may still be some variability in their ability to come back each year. Factors such as extreme weather conditions, pests, diseases, or poor soil quality can impact the plant’s ability to survive and regrow. Providing proper care and maintenance, such as regular watering, fertilizing, and pest control, can increase the chances of the plants returning each year.
To summarize, morning glories can come back year after year on their own in warmer and more tropical climates where they behave as perennials. However, in colder regions, they are typically grown as annuals and will not regrow without replanting. It’s important to consider the specific climate and growing conditions when determining whether morning glories will come back reliably in a particular area.
