Commercial Production of Ornamental Tropical Foliage Plants: Micropropagation

Figure 2. Plant tissue is placed into a sterile culture vessel. Credit: J. Chen, UF/IFASFlorida 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)

Florida Foliage House Plant Care: Adenium swazicum

Figure 2. A light pink flowering form of Adenium swazicum in a 10-inch pot. Credit: R. J. HennyAdenium 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.

Florida Foliage House Plant Care: ZZ Plant

Figure 1. Zamioculcas zamiifolia, commonly called "ZZ plant," performs well indoors. Credit: R. J. HennyZZ 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.

Florida Foliage House Plant Care: Adenium obesum (ENH1213/EP474)

Figure 1. Adenium obesum 'Blooming Fool' in full flower growing in a 10-inch pot.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.

Using Gibberellic Acid and Ethephon to Induce Flowers on Tropical Foliage Plants (ENH1186/EP447)

Figure 4. Bromeliad growers routinely apply Florel® treatments to induce shiny, colorful inflorescences.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.

New Florida Foliage Plant Cultivar: Pothos ‘Pearls and Jade’ (ENH1180/EP441)

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.
