Selected for fast, strong growth with wide
branching with excellent form. Stucturally superior in that no narrow crotch
angles form and branches are widely spaced to allow light to penetrate to the
interior of the tree. Tree develops as a
single timber like tree with strong apical dominance but equally broad and
upright spreading limbs following the leader. Behemoth has zero acorn
production in my planting of hybrid and species oaks. There was one year I
found 10 acorns underneath its canopy one year. That was it in the course of a 40 year old tree.
Unlike modern day oak cultivars, Behemoth (and Gigant) are selections
based solely on there growth rate and massive size including trunk caliper along with excellent
structural characteristics found often in old oak trees. This type of structure
resists wind, drought and helps bring the oak back to its glory years of 1000
year old trees free of knots, blight and insects.
Originally from a population of Quercus x McDanielii or
macrocarpa x robur in Illinois, I selected a few trees that showed the highest
hybrid vigor, large clean leaves and straight branching. It’s no or low acorn
production makes it ideal in some types of landscapes where acorn production is
not a priority but growth rate is. Wood quality is currently being evaluated.

Grafted onto seedling hybrid rootstock is ideal. Rooting would be the solution to keep the vigor of the tree intact. Using heat to speed callus is the best solution to increase takes on grafting. |
