The
Bur Oak is possibly the most majestic and long-lived of the Oaks one can
grow in Texas. Its canopy can span more than 60 feet in diameter
and its uppermost leaves can be over 100 feet above the ground. Its
specific epithet, macrocarpa, means "large fruit". The acorn
in the photograph, still in its frilly cup, is typical of the species.
Its deciduous leaves are very large and deeply lobed. Thankfully,
it is resistant to Oak Wilt. Two other readily available species
having resistance to that fatal fungal disease include: Quercus laceyi
(Lacey's Oak) and Quercus muehlenbergii (Chinkapin Oak).
It needs full to half-day
sun and is very drought-tolerant once established. However, young
specimens look best if given a deep watering every two weeks during a dry
summer.
