Eucalyptus Cultivars

Eucalyptus cultivars developed at the Florida Agricultural Experiment Station, an agricultural and natural resource research program of the University of Florida’s Institute of Food and Agricultural Sciences (IFAS), are patented, and a license is required for propagation.  Anyone buying plantlets should make sure that the seller is a licensed propagator.  Any violations should be reported to Florida Foundation Seed Producers, Inc. If your company is interested in licensing Eucalyptus cultivars, please contact the Florida Foundation Seed Producers, Inc.

The E.nergy™ Series
Eucalyptus grandis Cultivars
‘G1’ PPAF, ‘G2’ PPAF, ‘G3’ PPAF, and ‘G4’ PPAF

E.nergy™ ‘G1’PPAF, ‘G2’PPAF, ‘G3’PPAF, and ‘G4’PPAF are four newly released E. grandis cultivars with exceptional site and freeze tolerances.  These cultivars have potential for biomass production because they are greatly superior to the seedlings currently available in Florida; no commercial E. grandis clones exist in Florida.  The cultivars were developed at the University of Florida’s Insititute of Food and Agricultural Sciences, School of Forest Resources and Conservation. 

E.nergy™ ‘G1’PPAF, ‘G2’PPAF, ‘G3’PPAF, and ‘G4’PPAF have considerable potential for making a significant contribution to Florida agriculture and the general public by increasing E. grandis yield and quality for biomass production.  Energywood may be utilized for electricity generation by many utilities in Florida by cofiring with coal, for example.  Some utilities in southern Florida are now burning woody biomass to produce electricity and steam.  Woody biomass also has numerous other energy-related applications including direct combustion, thermo-chemical gasification, methane production, and, potentially, alcohol production.  Trees grown for energy applications may qualify for certain tax credits worth as much as $30 per dry ton.

E.nergy™ ‘G1’PPAF, ‘G2’PPAF, ‘G3’PPAF, and ‘G4’PPAF are fast-growing, straight trees with superior survival, tree size, form, coppicing, wood properties, and/or freeze tolerance/resilience.  Trees have grown well in a range of sites and conditions under evaluation in southern and central Florida.  The cultivars have demonstrated high energywood productivity on reclaimed phosphate mined lands.

Their outstanding selection qualities of tree size, form, coppicing, and freeze hardiness are complemented by desirable propagation characteristics.  On infertile “palmetto prairie” sites with minimal culture in southern Florida, trees have reached heights of 8m in 2.3 years, while on muck soils, they have grown to over 13m in 2.5 years.  On infertile bay dredge soils in central Florida, the trees have grown over 10m in 3 years. Similarly impressive growth has been observed on clay settling areas as well.

Plant patent applications for ‘G1’, ’G2’, ’G3’, and ’G4’ have been filed with the United States Patent and Trademark Office. The E.nergy™series is a trademark of Florida Foundation Seed Producers, Inc.
