FLORIDA NATIVE FERNS: PTROPICAL PTERIDOPHYTES

摘要

Plants are considered native to Florida if they were here at the time of European contact in the early sixteenth cen-tury (1516). Using plants native to Florida in our landscapes helps maintain the natural look of our state and can lead to more energyefficient landscaping. Florida has over 2,400 native species of plants, with some endemic to the state. They have survived through the years because they are adapted to our soils, temperature, and rainfall patterns. Each is associated with natural plantcommunities or ecosystems that occur throughout Florida. Although only about 25% of our native flora is in commercial production, interest in native landscaping continues to increase. Commercial and homeowner landscapes can benefit from learning more about native plants and how to use them in the landscape in formal beds, understory plantings or as specimen plants. Multi-media tools offer an easily accessible way to promote the use of native plants and their availability in the nursery trade. A PowerPoint presentation focusing on the use of ferns in understory plantings was developed to address these needs. The presentation begins with a key to fern identification features to assist viewers in distinguishing between different species. Featured nativeferns, terrestrial and epiphytic, are discussed with relation to origin, cultural requirements, availability, and landscape uses.
