Description and Uses
Quercus virginiana (Southern live oak) is a
tropical
tree from
Eastern North America . It is mainly grown for its
ornamental crops
, which have a
medium shelf life. The crop is harvested by
total removing. It starts flowering after
20 -
30 years. The yield will be
n/a, but in its top season there will be a yield of
n/a. Other crop types include;
edible roots, ornamental, timber, . The
{missing data} is used as
minor food . The
flower is used as "
anti-arthritic activity, " with
{missing data} (0% -
0%) as its significant
phytochemical. There is
inapplicable extracted by
no extraction method from the
tree's
{missing data} yielding
0% -
0% oil. The
tree's wood is called
Life oak wood and has a density of
870 -
890 kg/m³. Regarding firewood production the
tree's growing speed is
medium, it's energetic value is
4500 ckal/kg and the wood's drying speed is
medium. After
150 years the
tree can be totally removed as it reached its commercial and ecological goal.
Quercus virginiana has a lifespan of
500 years.
Environmental limitations
The tree is
