Coleus is a colorful and beautiful ornamental plant. However, many people are confused about its growth cycle, whether it is an annual or a perennial. This article will explore this question, guiding readers to understand the growth characteristics and habits of coleus.
I. Characteristics of Perennial Plants
Perennial plants are those that grow in the same location for multiple growing seasons, typically having the following characteristics: deep roots, dormancy during dry and cold periods, and survival through winter without dying. Coleus has a wide variety of cultivars, many of which are classified as perennial plants.
