Eucalyptus foliage has long been a staple for cut flower growers. But there is so much more available from this diverse species than the standard Silver Dollar or seeded eucalyptus.
There are over 700 species of eucalyptus trees growing natively on the Australian continent, as well as in California, Europe, Africa, and South America. Most prefer temperate climates because they are evergreen and more susceptible to hard frosts. However, the coldest regions of southeastern Australia, Tasmania, and New Zealand regularly see below-freezing temperatures. Certain species, through study, selection, and adaptation, are thriving in heavy snow, ice, and even subzero temperatures.
What we have learned from 18 years of research and over 1,000 individual plantings is that select eucalyptuses (Southern Eucs) are cold hardy and thrive in much of the U.S. (USDA zone 6B and above.)
What we have also learned from our local florists, ASCFG members, and ongoing trials with North Carolina State University is that flower growers want more textures, colors, and the ability to over-winter their trees for higher yields.
