Although Florida is known for its summer downpours, sometimes this state with its hot tropical climate experiences periods of drought. When droughts occur in a region, it’s important gardeners select shrubs, flowers and other plants that are able to tolerate extremely dry conditions. According to Floridata.com, a plant is considered drought tolerant if it’s able to survive a dry period that’s more than two to three months without watering.
