This series of Key Plant, Key Pests publications are designed for Florida gardeners, horticulturalists, and landscape professionals to help identify common pests associated with common Florida flora. This new 5-page publication, the tenth in the series, helps identify the most common pests found on oleander. This publication provides information and general management recommendations for oleander aphids, oleander caterpillars, sphaerosis gall, oleander leaf scorch, and scale. Written by Juanita Popenoe, Jacqueline Bourdon, Caroline R. Warwick, and Jianjun Chen, and published by the UF/IFAS Environmental Horticulture Department.

Snapdragons are a common plant in Florida landscapes and are one of the top ten fresh-cut flowers in the nation. This 5-page publication, written by Heqiang Huo and Jianjun Chen, explores the planting and propagation of snapdragons in Florida landscapes.

A chilling temperature is any temperature that is cold enough to cause plant injury but not cold enough to freeze the plant. Chilling injury can occur to tropical foliage plants if greenhouses become too cold or if plants are exposed to chilling temperatures outside of the greenhouse during packing and shipping. Dieffenbachia, commonly known as dumb cane, ranks among the top five most popular foliage plant genera produced and sold in the United States. This four-page fact sheet describes the chilling temperatures of Dieffenbachia cultivars in order to assist growers to better manage greenhouse temperatures. Written by Jianjun Chen and published by the Environmental Horticulture Department.
Florida nursery operators need to understand plant propagation principles and techniques so they can grow enough plants for sale. Micropropagation is a way to culture plant tissue to rapidly propagate a large number of plants. This 4-page fact sheet presents an overview of micropropagation to help growers evaluate it as a propagation technique for their own nursery operations. Written by J. Chen and R. J. Henny, and published by the UF Department of Environmental Horticulture, May 2015. (Photo: J. Chen, UF/IFAS)
Adenium swazicum is a species of desert rose whose gray-green leaves appear folded and are velvety to touch. It is sought after by collectors for its graceful, weeping branches and delicate flowers that occur in various shades of pink. It is a smaller plant with weaker branches and stems compared to other Adenium species such as Adenium obesum or Adenium arabicum. This 2-page fact sheet was written by R.J. Henny and J. Chen, and published by the UF Department of Environmental Horticulture, April 2014.
Amblyseius is a beneficial predatory mite endemic to the Eastern Mediterranean region. This species is considered a generalist predator, and readily consumes small soft-bodied pest species as well as pollen or plant exudates. Amblyseius swirskii has attracted substantial interest as a biological control agent of mites, thrips and whiteflies in greenhouse and nursery crops and is currently reared and sold commercially in Europe and North America for this purpose. This 5-page fact sheet was written by Mahmut Dogramaci, Garima Kakkar, Vivek Kumar, Jianjun Chen, and Steven Arthurs, and published by the UF Department of Entomology and Nematology, June 2013.
ZZ plant is enjoyed for its unique appearance, its ability to grow under low light conditions, and its tolerance to drought. ZZ’s naturally glossy leaves are so shiny that the plant appears to have been polished. This 2-page fact sheet was written by R. J. Henny and J. Chen, and published by the UF Department of Environmental Horticulture, July 2013.
Most Spathiphyllum are seen in flower when at market. The attractive white blooms, called spathes, are long lasting. With proper plant care, Spathiphyllum may produce blooms year after year. Spathiphyllum is a very attractive house plant even when not in bloom and adapts well to home and patio environments. This 2-page fact sheet was written by R. J. Henny and J. Chen, and published by the UF Department of Environmental Horticulture, June 2013.
Adenium obesum and its many hybrids are often seen in retail garden centers. They have vibrant floral displays in shades of red, white, pink, and yellow. Flowers average 2–3 inches in diameter and may be single, double, or even triple. The plants must be stationed in high light, 6 hours or more per day, to maintain flowering during the summer. Adenium obesum makes a dramatic specimen for a deck or patio but should be moved indoors in winter. This 2-page fact sheet was written by R. J. Henny and J. Chen, and published by the UF Department of Environmental Horticulture, May 2013.
Even though they are prized for their beautiful leaves, flowers are induced in tropical foliage plants for breeding and for marketing purposes. This 6-page fact sheet discusses several factors to consider when developing protocols for inducing blooms in tropical foliage crops. Written by R. J. Henny and J. Chen, and published by the UF Department of Environmental Horticulture, October 2011.
This dwarf, more highly branched and rounder cultivar of Aglaonema 'Silver Bay' developed as a whole-stem mutation that was found within a large population of Aglaonema 'Silver Bay' plants. This 4-page fact sheet was written by R. J. Henny and J. Chen, and published by the UF Department of Environmental Horticulture, August 2011.
Pothos plants are tree-climbing vines native to the Solomon Islands, but they flower seldom and never under greenhouse conditions or in interior environments. As a result, no hybridized pothos cultivars are known to exist. Because of the barriers to hybridization, a program was initiated at the Mid-Florida Research and Education Center (MREC) in Apopka, Florida, to induce mutations in order to develop new pothos varieties. Pothos ‘Pearls and Jade’® (Fig.1) is a mutation selection from a group of ‘Marble Queen’ plants. This 4-page fact sheet describing the new hybrid was written by R. J. Henny, J. Chen, and T. A. Mellich, and published by the UF Department of Environmental Horticulture, March 2011.
