Cultivars
With so much time and money invested in a poinsettia crop, finding the right cultivars
for your production environment is critical. These recommendations will get you started.
By John Dole, Allen Hammer and Jim Barrett
L
ast year’s switch to evaluating cultivars according to production style was well received, and we have continued that format with this year’s recommendations. We find that the best
cultivar for an individual grower depends on their location,
production practices, market and personal preferences, so our
emphasis remains focused on the various container sizes used and how different cultivars perform in those containers.
There are a large number of poinsettia cultivars that can be produced
successfully; too many for any one grower to be familiar with or even test
all of them. This list of recommended cultivars is meant to aid growers in

selecting cultivars to try, especially in light of the many new cultivars introduced each year. These recommendations are based on university trials and
observations of commercial crops. Primarily, this list includes cultivars that
have been in our trials for at least two years.
Allen Hammer is professor of floriculture at Purdue University. John Dole
is professor of floriculture at North Carolina State University. Jim Barrett
