Two-leaf nightshade, Solanum diphyllum, is a member of the Solanaceae or potato family. It is native to Mexico southwards to Costa Rica. It has escaped cultivation in Florida and grows as far north as Duval County and from Volusia County south to Miami-Dade County. A “bird-dispersed” volunteer, it occurs in urban and conservation areas and on disturbed land. The plants produce abundant berries with many many small seeds. This new 5-page publication of the UF/IFAS Environmental Horticulture Department is primarily intended for Florida gardeners, landscapers, and land managers, and it contains information on identification, flowering, fruiting, and management recommendations for this widely occurring plant. Written by Stephen H. Brown, Chris Marble, and Stephen F. Enloe.

Railroad vine is one of the most widely distributed beach plants in the world. The moving sand and salt spray make the beach environment a harsh one, and the plants that live there are specialized to colonize this environment. This new 7-page document, published by the UF/IFAS Environmental Horticulture Department, describes railroad vine’s leaves, flowers, fruit, planting and maintenance, and insect and disease problems. Written by Stephen H. Brown and Marc S. Frank.

Regenerated Sabal/Cabbage Palms (Sabal palmetto): Why and How

Sabal palms are held on a rack for six weeks.Palms are woody monocots characterized by the production of adventitious roots from the base of the trunk. Unlike the woody roots of dicots, such as oaks, gumbo limbo, and sea grapes, palm roots have no secondary thickening. Also, unlike trees, palms are incapable of repairing damage to their trunks. Most importantly, the life of a palm is dependent upon the continued good health of the single growing bud known as the meristem. Thus, if the palm bud is killed, the entire palm or the palm cane will eventually die. This 4-page fact sheet discusses harvesting and transplanting sabal palms, cropped transplants, and regenerated transplants. Written by Stephen H. Brown and Tim Broschat, and published by the UF/IFAS Environmental Horticulture Department, September 2017.
