[under construction] Perennials are plants that grow indefinitely. The shrubs and trees that comprise our landscapes are perennials, but these are referred to as woody perennials. The plants discussed here are herbaceous perennials, or plants with little or no woody tissue. However, under the continuous growing conditions of South Florida, some herbaceous perennials become woody shrubs. Likewise, plants that are normally woody shrubs in South Florida behave as herbaceous perennials in North Florida, where they are killed to the ground each winter.
