Unlike annual plants, which grow, bloom, and die all within the span of a single season, perennials are plants that can regrow each year in your yard. Perennials are much-loved for their low maintenance and curb appeal. While many perennials are flowering plants, not all have blooms.
To add a layer of complexity, whether a plant is annual or perennial can also depend on your growing environment. A plant that can overwinter in warmer climates, like Lantana, may be considered a perennial in those areas, where it would be considered an annual in colder climates where it would not survive the winter.
