Stephen H. Brown, Chris Marble, and Stephen F. Enloe

Two-leaf nightshade, Solanum diphyllum, is a member of the Solanaceae or potato family. The common garden tomatoes, peppers, and eggplants also belong to the Solanaceae family. The genus Solanum is associated with plants known as nightshades.

Melia azedarach: Chinaberry

Edward F. Gilman, Dennis G. Watson, Ryan W. Klein, Andrew K. Koeser, Deborah R. Hilbert, and Drew C. McLean

Chinaberry is a round, deciduous, shade tree, reaching 30 to 40 feet at maturity and growing five to 10 feet during the first and second year after seed germination. Growth slows as the tree reaches 15 or 20 feet tall. It is successfully grown in a wide variety of situations, including alkaline soil where other trees might fail. Truly an urban survivor, Chinaberry has become naturalized in much of the south.

Wildland Weeds: Paper Mulberry, Broussonetia papyrifera

Eric C. Morgan, William A. Overholt, and Brent Sellers

A UF/IFAS numbered Organism ID. This document discusses the invasive plant species, paper mulberry (Broussonetia papyrifera), detailing its historical significance, ecological impact, and current distribution. Originally used for paper production in ancient China, paper mulberry has become a widespread invasive species, disrupting natural vegetation across various regions, including Florida. The article highlights its ability to colonize disturbed areas, spread through fruits and root systems, and form dense thickets. It also provides identification features and recommendations for managing its spread. The document is part of the UF/IFAS Extension series on invasive plants. Publication date: March 2004.

Leucaena leucocephala, White Leadtree

Michael G. Andreu, Melissa H. Friedman, and Robert J. Northrop

In Florida, white leadtree is a prohibited species and therefore is not used in commercial applications in the state. However, in its native range it is used as a source of charcoal, fuel, and lumber. It has also been planted as a windbreak for crops such as coffee and cocoa, and some ranchers use the tree as a source of both shade and forage for cattle, with the pods being an excellent source of protein.

Fire and Invasive Plant Interactions

Deb Stone and Michael Andreu

Prescribed fire and invasive species are two common land management concerns in Florida; therefore it is important that land managers have a solid understanding of their interactions and how they affect the surrounding ecosystems. These interactions can be roughly categorized into two groups: the effects of the invasive plant on the fire regime and the impacts of fire on the invasive plant or other flora. For this review we chose four invasive species in the southeastern United States that cover a range of interactions with fire: Cogon grass (Imperata cylindrica), Chinese tallow (Triadica sebifera), old world climbing fern (Lygodium microphyllum), and Japanese climbing fern (L. japonicum). This publication details basic information on each species, what is known about how it interacts with fire, and synthesizes this knowledge into concrete management recommendations.

Cat's-Claw Vine, Dolichandra unguis-cati—A Showy but Invasive Plant in Florida

Niels Proctor and Jason Smith

Cat’s-claw vine is a neotropical, climbing perennial that produces large and showy yellow flowers in the springtime. It is valued as an ornamental, particularly in dry areas, because it needs little water or care and can climb almost anything, covering fences and other structures with an attractive carpet of leaves and flowers. Unfortunately, the aggressive nature of the vine has made it a major weed in China, Australia, South Africa, and parts of the southeastern United States. This 6-page fact sheet provides guidance on identification, control, and similar native vines for home landscapes.

Help Protect Florida's Natural Areas from Invasive Plants

S. F. Enloe and K. A. Langeland

The article emphasizes the importance of recognizing and removing invasive plants from private properties to prevent their spread. It advocates for using native plants in landscaping and seeks collaboration among property owners, land managers, and officials to protect Florida's ecosystems. Sharing information and raising awareness are key to effective conservation efforts.

Ricinus communis, Castor Bean

Melissa H. Friedman, Michael G. Andreu, Heather V. Quintana, and Mary McKenzie

This document provides an overview of the castor bean plant (Ricinus communis), detailing its characteristics, uses, and potential hazards. It describes the plant’s growth habits, physical features, and its classification as an invasive species in Florida. The article also highlights the plant’s allergenic properties and the toxicity of its seeds, which contain ricin. Additionally, it outlines the commercial, horticultural, and medicinal applications of castor oil derived from the seeds, emphasizing the importance of careful handling due to the plant’s toxic nature. Original publication date May 2010.
