Pin oak, Swamp Spanish oak
Fagaceae (Beech Family)
Flaigg, Norman G.
with spreading to horizontal branches, very slender pinlike twigs, and a broadly conical crown. Pin oak is a stongly pyramidal tree
with a distinct central leader, growing 60-70 ft. or taller. Instead of the gnarled, massive qualities of most oaks, pin oak has a more graceful, slender appearance. Old trees become high-crowned after shedding lower limbs. Dark-green foliage becomes dark-red in fall. Leaves persist into winter.
Named for the many short side twigs or pinlike spurs. A popular, graceful lawn tree
with regular compact form and fine-textured foliage, Pin Oak is hardy and easily transplanted because the shallow fibrous
root system lacks tap
