Manchineel (*Hippomane mancinella*) is also called the tree of death and is one of the most toxic tree species on the planet. These trees are so hazardous that they are often accompanied by a bright red warning band. Every single part of the plant—from the leaf sap to the fruit and the stems—can cause a painful death!

Hyssop-leaf sandmat (Euphorbia hyssopifolia) is a sandmat that’s indigenous to the southwestern part of the United States. A sandmat is a plant in the genus of Euphorbia that thrives best in deserts. Hyssop-leaf sandmat has a milk-white sap in its stem—just like the milkweed. It’s also known as hyssop spurge, eyebane, wart weed, and chicken weed.

Rough cocklebur (Xanthium strumarium) is likely native to North America but has become widely naturalized around the world. The burred seed pod is buoyant and can be dispersed along waterways in addition to becoming hooked in the fur of passing animals. The plant has been used for medicinal purposes but is also quite toxic and dangerous.

White leadtree (Leucaena leucocephala) is a small tree native to Mexico and Central America. Planting white leadtree makes the soil fertile as other Legumes do. It has been also used for livestock feed and firewood. This tree is also called a "miracle tree" for its many uses.

Portia Tree (Thespesia populnea) is a tropical, evergreen tree valued for its rich, dark wood. Commonly found growing in coastal areas. Thrives in full sun with moist but well-drained soil. It is drought, wind and salt-tolerant. Edible leaves and fruit can be eaten fresh or cooked. The bark, roots, leaves, flowers and fruit have been used medicinally.

Tropical almond is grown commonly as an ornamental tree. It is prized for its ability to provide shade with its large leaves. These leaves are commonly used in aquariums by fish breeders for their ability to lower the pH and heavy metal content of the water. Although the fruit of the tropical almond is edible, the taste is slightly acidic.

Bird lime tree is a medium-sized tree with sticky fruit. In China, the fruits are pickled with ginger as a delicacy, but in its native setting, insects and even small birds can get caught and trapped on these fruits, giving rise to another of this plant's common names, the Bird catcher tree.

Neem tree (*Azadirachta indica*) is a flowering tree species related to mahogany and with an appearance similar to that of the chinaberry tree. For centuries, it has played an important role in Indian culture. Commercially, the neem tree is used to produce neem oil, pesticides, and cosmetics.

Caribbean stylo is a resilient tropical legume often found embracing the sun-soaked savannas. With its hook-like seed appendages, it clings to passersby for seed dispersal. Its leaves, trifoliate and vibrant, hint at its role as a nitrogen-fixing agent, enriching the soils where it sprawls. The wiry stems and yellow flowers bear the hardiness that allows caribbean stylo to thrive even in arid conditions.

Apple of Sodom, or Calotropis procera, is an extremely poisonous plant. The fruit of this plant ripens and bursts, causing the seeds to scatter. In Jamaica, the fibers inside of the fruit are collected and used to stuff pillows.

Florida hammock sandmat is an intriguing species, typically growing in arid conditions where its water-storing stems give it an edge. These pencil-like stems burst forth in a vibrant green, accentuating the special 'cyathia' or false flowers that define the Euphorbia genus. These blooms boast pronounced glands that mimic petals, a characteristic adaptation to attract pollinators in sparse desert environments.

Bayhops (Ipomoea pes-caprae) is an herbaceous climbing vine that is salt tolerant and commonly found growing wild along ocean shores of North America, from Florida to Texas. Flowers bloom in summer and fall, opening in early morning and closing before noon each day, giving the plant its name. Seedpods appear shortly after flowers fade.

The three lobed leaves are purple and sticky when young and become bright green with age. The small red flowers with yellow centres appear in clusters. These are followed by cherry-sized seed pods that are poisonous. Powdery mildew fungal disease was reported. There are many common names for Jatropha gossypiifolia including: bellyache-bush, black physicnut, and cotton-leaf physicnut in English; pinon negro, pinon colorado, and tua-tua in Spanish; medicinier noir and medicinier rouge in French; mamoninha and peao-roxo in Brazil; jarak merah and sibidigua in India.

The flame of the woods is a popular warm-weather garden shrub due to its versatility and unique, bright red leaves. It can be used as a hedge, in flower beds, or even grown as a small tree.
