As every gardener knows, annual plants flower only once during their life cycle, and need to be replaced each year. Perennials, on the other hand, can flower many times, cycling between flowering and vegetative growth for many years, in time with the changing seasons. Although flowering in annuals has been extensively studied using the model plant Arabidopsis thaliana (thale cress), few studies have looked at the regulation of flowering in perennials.
