Ranunculus Perennial Or Annual?

Ranunculus, also known as buttercups, are generally considered to be perennial plants. However, their classification as perennials or annuals can vary depending on the specific variety and growing conditions. In colder climates, ranunculus plants may be treated as annuals, as they are not frost-tolerant and will not survive harsh winter conditions. In these regions, they are typically planted as annual bedding plants or grown from bulbs each year. In milder climates with mild winters, ranunculus plants can often survive and return year after year, making them true perennials.
