As explained on the Home Page, the MegaFlora Tree® is a hybrid Paulownia tree
created by a two-step process. The first step involved crossing three Paulownia species
– P. elongata, P. tomentosa, P. fortuni select — via standard plant breeding techniques
to create the 3xP tree. Most of the phenotypic characteristics of 3xP trees are those of
P. elongata. The second step involved creating a hybrid of the 3xP tree with a specific
non-Paulownia hardwood tree species to form the proprietary “3xP hybrid”, or
MegaFlora Tree®.
Therefore, the MegaFlora tree is a trans-genera clone; it
is not a genetically modified organism (GMO). As is the
case with all trans-genera clones (example: peach x
apricot = sterile nectarine), it is seed-sterile and therefore
non-invasive.
Whereas 3xP trees are superior in many ways to any one
of the three Paulownia species involved in the three-
species genetic cross, MegaFlora trees possess even
greater benefits compared to the parent non-hybrid 3xP
trees; MegaFlora trees are:

Dr. Allen’s initial work that led eventually to the creation of the MegaFlora Tree occurred in the late 1990’s with his participation in a plant breeding effort to develop a 3-way cross of three Paulownia species: P. fortunei, P. tomentosa and P. elongata. The underlying purpose of this effort was to attempt to create a new Paulownia tree that phenotypically expresses the most positive features of all three species into a new cross-bred tree and as a result would have greater commercial value; especially the features of fast growing, higher quality wood, better tolerance to environmental extremes, coppicing, and resistance to insect and rot. The effort was successful. In Genesis Agroforestry, this new and distinct variety of Paulownia tree is called the “3xP tree” and its genotype is approximately 40% tomentosa, 40% elongata and 20%.
