One distinction between annuals and perennials is that annuals flourish in many different climates, while perennials thrive only in specific US department of agriculture hardiness zones, depending on the plant. Another difference is that annual plants complete their life cycle in a single season, especially for one year, as perennials grow and blossom for more than two years.
Once annual plants complete their life cycle, they die. They need to be replaced each year, hence the name ‘annuals.’ Perennials are plants that generally live for more than two years. These plants attain more height than annuals, which are known for their bushy quality.
However, unlike annuals, they produce fewer flowers. Annuals and perennials both come in a rainbow of colors, and they also come in different sizes, shapes, and scents.
